Title: Casing string back cementing method
Inventor: AKHMADISHIN FARIT FOATOVICH
IPC: E21B33/14
Filed: 2019-08-30
Granted: 2020-05-13
Abstract: FIELD: oil and gas industry. 
     SUBSTANCE: invention relates to oil and gas industry, namely to a method for cementing a casing string in a well shaft with back circulation of a grouting mortar. Tool is lowered to the borehole of the casing string. Grouting mortar is pumped into space between casing string and well bore. Volume of grouting mortar is taken from preliminary calculated volume of space between well bore and casing string. At that, after lowering into well shaft of casing pipe string, technical fluid is pumped inside casing string in amount equal to volume of inner space of casing string of pipes. In addition, a ball valve is installed between the cementing head and the driving drill pipe. Rotary cementing head is used as cementing head. During pumping of grouting mortar with permanent rotation of casing string reciprocation is carried out to height of 1–1.5 m at a rate of not more than 1 m/s times until completion of cementing process. Casing string is continuously rotated clockwise at 10–12 rpm using rotor of drilling rig or top power drive. Rotation of the casing string creates vortex flow of the grouting mortar. Inverse circulation of borehole fluid is controlled through rotary valve of cementing head. 
     EFFECT: expansion of technological capabilities and increase the efficiency and reliability of the process due to more complete replacement of drilling fluid by grouting mortar behind the casing to obtain a continuous and hermetic cement sheath along the entire length of the casing.

Abstract: FIELD: technological processes. 
     SUBSTANCE: invention is intended for industries using high-grade carbon dioxide and can be used in production of liquid carbon dioxide. Mixture of natural carbon dioxide and water vapor is supplied to gasholder 1 with open valve 2. From gasholder at pressure of 0.17 MPa and temperature of 10 °C through open valve 4 is supplied to adsorber of moisture 7 with synthetic zeolite of grade KA-CO. At that time second adsorber 8 is in regeneration. Valves 3, 5, 9–11, 14 are closed, valves 4, 6, 12 are open. Dry gas is sucked from adsorber 7 by double-stage oil-free carbon-dioxide compressor 15. After the first compression stage, gas with pressure of 0.4 MPa and temperature of 70 °C enters intermediate water cooler 16 where it is cooled. Further, the cooled carbon dioxide at temperature of 15–30 °C is sucked by the second stage of the compress and compressed to pressure of 1.75 MPa and temperature of 120–130 °C. Then, the main portion of the gas is injected into water cooler 17, which passes the gas for condensation, and small portion 1.92–1.95 % of gas flow is supplied to adsorber 8, through valve 6, for regeneration of zeolite. Duration of regeneration per day makes 0.92–1.1 hours. After regeneration and cooling of zeolite in adsorber 8, duration of 2.8–3.12 hours, it is put into operation, and working before adsorber 7 is switched to regeneration. Carbon dioxide and water vapors from regenerated adsorber 8 at pressure 0.17 MPa with open valve 9 are supplied to water cooler 13, where they are cooled to temperature of 30–50 °C and carbon dioxide is dried. Further, when valve 14 is open, gas is mixed with dried carbon dioxide after adsorber at mixture temperature of 10.5–11 °C and sucked by first stage of compressor 15. 
     EFFECT: invention increases efficiency of installation of liquid carbon dioxide from underground sources at constant operating costs, which will reduce cost of obtained liquid carbon dioxide.

The method consists of determining the following indicators: C-reactive protein in the blood (C) (mg/l), homocysteine (G) (mkM/l), testosterone (T) (nM/L), while each feature is assigned its numerical value meaning that each feature is assigned an experimentally determined weight value in the form of a product of a constant coefficient and a numerical value of the laboratory indicator: (1.61412) and the value of the indicator of C-reactive protein in the blood (mg/l), (1.05771) and the value of the indicator of homocysteine (mkM/l) in the blood, (-0.34785) and the value of the testosterone index (nM/L) in the blood and is summed with a constant equal to (-16.63326), followed by the calculation of the LVH probability formula. At a probability value of 50% or higher, a high risk of left ventricular hypertrophy is predicted in a patient with OSA with subsequent development of cardiovascular complications; at a probability value below 50%, the risk is low.  
     EFFECT: application of the invention makes it possible to develop a method for determining the probability of left ventricular hypertrophy (LVH) in a patient with OSA by a limited number of laboratory signs that individually and combined have high sensitivity and specificity.
