METHOD OF PREPARATION OF AERATED VISCOELASTIC COMPOUND AND ITS INJECTION INTO WELL

摘要

oil and gas production; applicable in preparation for and performance of repair and isolation work in wells. SUBSTANCE: compound is mixed with liquid in ejector. Active medium is used in form of mixing liquid supplied at pressure of not lass than 20 Mpa. Liquid is preliminarily filtered. Dry polymer compound is loaded into bin and supplied to ejector in form of passive medium by screw conveyer. Produced mixture is aerated with gas at pressure from gas source and injected into well by pump handling gas-liquid mixtures. Level of mixture in vessel is maintained at height of not less than 0.5 m. Shutdown of pump is course of compound injection into well shall not exceed 0.5 h. EFFECT: lower cost of repair and isolation work. 3 cl
