METHOD FOR CLEANING HIGH-PRESSURE GAS-COLLECTING RESERVOIRS Russian patent published in 1998 - IPC

FIELD: gas production industry. SUBSTANCE: method implies removing of liquid and mechanical impurities from internal surfaces of telescopic gas pipelines by using gas in function of pressure-forcing medium for introducing gel-like mass into pipeline. This gel-like mass is preliminarily pumped into mobile multiple-use chamber. Gel-like mass is held in this chamber in static condition until reaching monolithic structure of gel-made piston. After that, thus produced gel-made piston is pressure-forced into gas-collecting reservoir by means of gas pumped under pressure. EFFECT: higher efficiency. 1 dwg
