The in - house system evaluation and field application showed that an excellent oil film for shielding temporary plugging could be formed near borehole wall and both plugging and recovering rates of permeability reached more than 90 % when the added amount of the broad spectrum oil film temporary plugging agent gpj reached 3 % ; skin factor decreased by 7 . 4 to 10 times and production increased by 1 . 82 to 2 . 96 times compared with conventional technology 结果表明，当广谱“油膜”暂堵剂gpj的加量达到3 %时，可在近井壁处形成很好的屏蔽暂堵“油膜”带，渗透率堵塞率和恢复率皆大于90 % ，与常规屏蔽暂堵技术相比，可使油层损害程度降低7 . 4 ~ 10倍，产量提高1 . 82 ~ 2 . 96倍，而且与油层渗透率和温度无关。
