| 摘 要： | 针对油田注水开发的中后期油井含水率升高，甚至水淹等问题，研制出ＳＤ选堵剂，并进行了室内模拟试验和性能评价。结果表明，选堵剂（ＳＤ）具有好的油溶性，成胶时间和软化温度可调，堵水率９８％以上，堵油率１０％左右，封堵强度可达１５ＭＰａ／ｍ以上。现场应用１２４井次，有效率９０％以上。

| Abstract: | Due to increase of water-bearing or water-flooding in oilfield,SD selective plugging agent is developed.And simulation test and performance evaluation have been done at home.The results show that the selective plugging agent(SD) has good oil solubility,gelatinizing time and softening temperature are adjustable,water shutoff ratio is over 98% while oil shutoff ratio is about 10% and break-pressure gradient is above 15 MPa/m.The field application in 124 wells indicate that the effectivness is above 90%. |
