Abstract: FIELD: oil and gas industry.SUBSTANCE: invention relates to the field of oil and gas industry and can be used for justification of gas field operating practices, including systems for production and treatment of gas for transportation. In the method for determining the parameters of the gas field operating practices, wherein the produced gas sequentially passes through the systems of gas production and treatment for transportation, their gas dynamic characteristics (GDC) are determined, which limit the working areas of these systems in the form of the gas pressure dependences at the inlet of the gas processing system for transportation on the gas output. Furthermore, a possible range of the filed operating practices is determined, which is located in the intersection zone of the working areas of the gas production and treatment systems.EFFECT: justified range of possible operating practices of the field, within which the most optimal mode can be assigned, based on the preset conditions for each specific field.1 cl, 3 dwg

Title: Method for suppressing pressure pulses in pipelines
Inventor: Ershov Sergej Ivanovich
IPC: F17D1/20

Granted: 2021-09-30
Abstract: FIELD: pipes. 
     SUBSTANCE: invention relates to methods and means for suppressing pressure pulsations of a liquid (water hammer) or a gas in pipelines. The method consists in the fact that the liquid or gas flow of the pipeline wherein the pressure pulses act is divided into N parts further directed to channels with different delays due to the different lengths thereof, therefore, pulses from different channels with a power reduced by N are summed up at the output, coming in succession due to the different times of passage through the channel. Accordingly, the pulse front is spread and the undesirable impact on the pipeline is reduced. The delay of each channel is calculated by the formula Tn=T+delta*(N-l), wherein T is the delay of the shortest channel, Tn is the delay in the N th  channel, delta is the increment of the channel delay when the number thereof is increased by one, N is the number of the channel. 
     EFFECT: levelled rising rate of the pressure pulse front of a liquid or a gas in a pipeline and a corresponding reduction in the negative impact on the pipeline.
