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 結(jié)果表明,當(dāng)廣譜“油膜”暫堵劑gpj的加量達到3 %時,可在近井壁處形成很好的屏蔽暫堵“油膜”帶,滲透率堵塞率和恢復(fù)率皆大于90 % ,與常規(guī)屏蔽暫堵技術(shù)相比,可使油層損害程度降低7 . 4 ~ 10倍,產(chǎn)量提高1 . 82 ~ 2 . 96倍,而且與油層滲透率和溫度無關(guān)。
