摘要:
针对江苏低渗透油田开发面临水井注水难、注水压力高的问题,开展了注表活剂降压增注研究。研制了超低界面张力表活剂体系(0.5%RD-06+1.0%助剂A),能与江苏原油形成10-3 mN/m数量级超低界面张力,并具有抗稀释抗盐能力强、稳定性好的特点。岩心降压模拟实验表明,表活剂复配体系可使注入压力平均下降38.3%; 岩心含油饱和度越高,驱替压力下降幅度越大,该配方适应注水井近井地带含油饱和度大于40%的注水井降压增注。
Abstract:
The injection pressure of some water flooding wells are very high in low-permeable reservoirs of Jiangsu oilfield.A surfactant system(0.5% surfactant RD-06+1.0% accessory ingredient A),which has ultralow interfacial tension(as low as 10-3 mN/m order of magnitudes)with crude oil taken from Jiangsu Oilfield,was developed to decrease injection pressure and improve injection volume.The combined system has good resistance to dilution,strong anti-salt and high thermal stability.Decreasing pressure experimental results show that water injection pressure can be decreased by 38.3%.The bigger the oil saturation of core is,the higher decrease of injection pressure is.For targeted wells,more than 40% oil saturation is expected.
