石油磺酸盐和环烷酸盐表活剂是一种较好的化学驱油助剂,经室内评价可作为稠油热采添加剂使用。经克拉玛依稠油区块33口井先导性试验证明,具有显著降粘和增产作用,试验井有效率达78.8%,单井周期增油平均达131t,每吨化学剂增产41t,具有较高的经济效益和广阔的应用前景。
Petroleum sulfonate and naphthenate surfactants are good chemical oil-displacing aids and can be used as heavy oil thermal recovery additives by indoor evaluation. The pilot test of 33 wells in the Karamay heavy oil block proved to have significant viscosity reduction and stimulation effects. The effective rate of the pilot wells was 78.8%. The average oil production per single well was 131t and the yield per ton of chemicals was 41t. Economic benefits and broad application prospects.
