Authors: Xu Yaqin 
Published: June 2020

Abstract
In reservoir dynamic analysis, oil well production volume and level data are important indicators for quantitative evaluation of oil well production status. Under the existing technical conditions, the liquid production volume of oil well can be calculated by using the recovery value of the liquid level after the well is stopped, and its size is the comprehensive reaction of the oil well’s fluid production status. At present, there are 386 annular flow Wells in our mine. All are measured in this way. At present, the main problem is that the oil level recovery method varies greatly, and the daily measurement is different. Therefore, under the current situation that the number of total ore ring Wells increases, the problem of oil quantity accuracy is the key to the formulation of oilfield development plan and dynamic analysis, which must be solved.

Authors: Zhang Yue 
Published: June 2020

Abstract
There are many provenance systems in Gubei sag of Es3. Es3 is one of the main oil-bearing horizon of oil and gas exploration in gubei sag. Because of the great depth, the reservoir property is relatively poor. Influenced by factors such as sedimentary type and diagenesis, the reservoir characteristics of different provenance systems are different. The sedimentary type not only restricts the original physical properties, but also influences the late diagenesis. In the same diagenetic stage, there are differences in the physical properties of different sedimentary types, in the same sedimentary type there are also have many differences between different sedimentary microfiches. The fan delta is the best, and the second is the underwater fan; the best part of the fan delta is the river channel and estuary sand bar in the front of the fan delta. The influence of different provenance system by depth, rock characteristics, the moving distance of different factors, in the stage of diagenesis, diagenetic types and other aspects are different, these factors continue to transform the reservoir. Ultimately these factors lead to the Kendong and Gudao provenance systems have the best reservoirs, Changdi second, Chengdong worst.

Published: June 2020

Abstract
In view of the lack of theoretical research on plane equilibrium injection-production adjustment in water drive reservoir, the production prediction method under the condition of variable pressure difference of production well is deduced according to Buckley Leverett non-piston displacement theory. Taking the same degree of extraction as the goal, the adjustment method of plane equilibrium injection-production per unit time is put forward. The evaluation coefficient of the optimal equilibrium injection-production scheme is defined, which can guide the optimization of the equilibrium injection-production scheme. Through theoretical model analysis, it is considered that the adjustment method of plane equilibrium injection-production is reasonable and reliable. Seven kinds of adjustment schemes are designed for BZ oilfield in Bohai Sea. Of equilibrium displacement time. When the equilibrium displacement time is more than 10 years, the increment of recovery degree slows down to about 1.8%. Equilibrium injection-production adjustment was carried out for 1195 sand body in BZ oilfield. The sand body increased oil by 25m3/d per day, and the natural decline rate decreased by 1.1%.

Authors: Xiao Jie , Ni Zhongxin 
Published: June 2020

Abstract
We use the MGARCH-BEKK / DCC model to study the volatility spillover effects and dynamic correlations between industry indexes. We selected indexes for four industries: real estate, raw materials, manufacturing, and banking. The research results show that the real estate industry will be greatly affected by the manufacturing industry, raw materials industry, and banks, and there are two-way fluctuation spillover effects between them. The raw material industry is mainly affected by the manufacturing industry, and it is also affected by real estate and banks, but the impact is relatively small. Banks have influence on the other three industries, especially on the real estate and manufacturing industries. Manufacturing mainly affects the real estate and raw materials industries, but it has less impact on banks. In addition, the DCC coefficient between stock indexes is positive for most of the time period. The dynamic correlation between the real estate index and ICBC stocks, and the dynamic correlation between the raw material index and ICBC stocks have significant asymmetry, and to some extent, their fluctuation characteristics are similar.

Abstract
In the test of mechanical properties of deep-sea sediments, hydraulic cylinders are often used to drive the probe into the sediment. However, due to the limitation of the stroke of the hydraulic cylinder, there is a limit to the depth of penetration of the probe. In order to solve the problem of limited travel, a penetration device that relies on hydraulic motor to drive the probe is designed. Through the co-simulation of AMESim and Simulink, the valve-controlled hydraulic motor system is analysed under the control of conventional PID control strategy and fuzzy PID control strategy. Simulation results: In terms of step response, the fuzzy PID control is 7.12% faster than the traditional PID control, and the overshoot is reduced by 44.4%. Under the step interference signal, the fuzzy PID control has an anti-interference ability improved by 60.7%compared with the traditional PID control. In terms of energy consumption, fuzzy PID control saves 1.08% energy compared to traditional PID control.

Published: June 2020

Abstract
With the progress of science and technology and the improvement of people’s living standards, the comprehensive performance requirements of automobiles are also increasing. Reducing engine’s vibration and noise is one of the important research contents in the field of automobile research. An experimental study was performed to investigate the effect of injection parameters on engine’s vibration at idle speed by using a four-cylinder high pressure common rail diesel engine. On the premise of not changing the components, the influence of each parameter on the vibration is compared and analyzed by changing the parameters such as main injection timing, interval of pilot-main injection, pilot injection quantity and rail pressure. The test results show that the vibration of diesel engine can be reduced by delaying the main injection timing properly, and the optimal interval of pilot-main injection is related to the main injection moment and the quantity of fuel injection. The determination of the pilot injection quantity must be determined by the pilot-main injection moment and the cycle injection quantity together in order to achieve vibration reduction. The increase of rail pressure will increase the vibration of the whole machine. Thus, the proper injection strategy is conducive to improve engine vibration characteristics.

Published: June 2020

Abstract
The determination of sand content is related to the accuracy of soil and water loss measurement. With the development of science and technology, there are many advanced sediment content measurement technologies. However, due to the differences and complexity of soil conditions in various regions, The applicability of this method for sand content measurement needs to be verified. This article explores the method for measuring sand content in red soil on the conditions of simulated rainfall and runoff experiments, and verifies the measurement accuracy of water samples with different sediment contents using the gravimetric method. The results show that when the sediment content is small, the error of the specific gravity method is large, and its accuracy increases with the increase of the sediment content, and the accuracy is the highest when the sediment content is about 40g/L. In addition, the fitting curve is used in this paper. The sediment content is measured and compared with the drying method. The experimental results show that the measurement accuracy is higher than the specific gravity method, but the results are different from the drying method.

Abstract
In order to study the thermal stress of the GIS shell under normal internal pressure in the sunshine environment, First, the 24-hour temperature field on the surface of the GIS shell of a substation is detected for and the temperature change curve is plotted. Then the ANSYS software is used to carry out finite element stress analysis including temperature field on GIS shell. During the analysis, select the highest temperature and lowest temperature periods, fit the temperature distribution curve of the cross section of the shell varying with the angle under the two conditions, and apply the corresponding temperature load of the two conditions to obtain the stress distribution and stress amplitude distribution. The results show that under normal sunlight environment, the stress of the shell without stress concentration is less than 30Mpa, and the stress variation value caused by diurnal temperature difference in most areas of the shell is within 5MPa, and it can reach about 10Mpa at the top where the stress concentration occurs. This study analyzes the stress distribution and fluctuation range of the GIS shell under the solar radiation, which provides important data support for the safety evaluation of the GIS shell.

Authors: Ye Zhanghuang , Deng Chenxia 
Published: June 2020

Abstract
Petroleum is the world’s most important primary energy. The global petroleum market fluctuation will threaten China’s energy security. China’s petroleum foreign dependency reached 67.4% in 2017. General speaking, quick petroleum price rising and high dependence on foreign petroleum are likely to have an adverse impact on the economy. However we will seek the truth by using data. The paper has analyzed the correlation between GDP growth of 3 countries (US, China and Japan) and 2 independent variables (international petroleum price rising and dependence on foreign petroleum) by using the econometric model. As for US, international petroleum price rising has no remarkable effect on GDP growth. The dependence on foreign petroleum is positively correlated with GDP growth: 0.14249. As for China, both international petroleum price rising and dependence on foreign petroleum have a negative correlation with the GDP growth: -0.02669 and -0.24123 respectively. As for Japan, both international petroleum price rising and dependence on foreign petroleum have no significant impact on its GDP growth. The conclusion illustrates that US and Japan have been well rewarded from their reasonable investment and exploration on the overseas petroleum resources.

Authors: Ye Yufeng , Chen Xingyang , Xie Haoping , Liu Huibin 
Published: June 2020

Abstract
Serious bending deformation of the tubes was found in the tubular furnace at a petrochemical company. In order to find out its specific reason, Thickness measurement and metallographic analysis were conducted on the problematic part of the furnace tube. Stress analysis by using CAESAR was carried out, in which the working conditions were considered. The results show that the microstructure of the furnace tubes was not abnormal, and there is no overheating, creeping and deterioration damage was existed during operation. Stress analysis show that the primary and secondary stress values of each node were less than the allowable stress for furnace tubes under current condition. However, the secondary stress will exceed the allowable stress when the furnace tube is bended up to 400 mm. Therefore, in order to avoid the replacement of furnace tube and the unnecessary economic loss, the tubes could be used safely under closely monitored after structural rectification.
