WELL COMPLETION METHOD Russian patent published in 1997 - IPC

FIELD: oil and gas industry. SUBSTANCE: this relates to completion of oil and gas wells at their construction. According to method, lowered down on productive tube string is filter with telescopically extending pipe connections in production zone of bed. Prior to cementation, pipe connections are extended with the help of additional forcing-through plug with destructible diaphragm. Forcing-through of this plug is effected by chemically destructible viscous-resilient liquid such as polyacrylamido-chalk solution, and after that well is cemented according to standard procedure with use of cementing machines. After waiting for hardening of cement slurry, muriatic acid solution is injected to destroy viscous-liquid in spaces of filtration holes, and space of productive tube string is connected with productive bed. Then, income of oil or gas is initiated. EFFECT: improved quality of initiating bed product inflow to well. 4 dwg
