摘　　要：对于疏松砂岩油藏,采用压裂充填的方式进行防砂的井,是否有必要在射孔后进行负压放喷作业来解除射孔带来的压实带、炮弹碎屑的污染,之前一直没有统一的认识,通常根据作业难易程度来选择是否进行负压放喷。本文通过对辽东湾地区某油田疏松砂岩油藏投产的一批井的产能情况进行分析,来确定负压放喷作业对于压裂防砂井来说是否可有效提高油井产能。For unconsolidated sandstone reservoirs,a well that uses a frac pack for sand control,whether it is necessary to perform negative pressure discharge after perforation to remove the contamination of the compaction zone and shell debris caused by perforation,there had been no consensus.Negative pressure jetting is usually chosen according to the difficulty of the operation,this paper analyzes the productivity of a group of Wells in an unconsolidated sandstone reservoir in Liaodong Bay area,to determine whether negative pressure jetting can effectively improve well productivity for fracturing and sand control Wells.
