摘　　要：GCC化学剂是近两年国外用于清除含油岩屑、地面油污所使用的一种新型化学剂,具有化学惰性、无毒、不燃、无污染性、可循环使用等特点。对GCC化学剂提高原油采收率驱油机理试验研究结果表明,该化学剂具有一定的驱油效果。其驱油作用机理主要是通过降低油水间的界面张力,改变岩石表面的润湿性和乳化携带以及乳化捕集,作用类似于表面活性剂驱油。该化学剂具有较好的溶解性、配伍性、抗盐性和耐温性等,可以作为类似海1块普通稠油油藏提高原油采收率的接替技术推广应用。Chemical GCC was used abroad to remove oil cuttings and surface oil dirt in recent two years, it was inert, pollution - free, non - combustible, recyclable etc. The oil - displacement mechanisms of GCC chemicals were studied. The results showed that GCC has some certain effects on oil - displacement. It could reduce water - oil interfacial tension, change wetting ability of rock surface, and it has emuls - entian and emuls - eutrap abilities. The function of GCC is similar to that of surfactant. GCC has good solubility, compatibility, salt resistance and temperature resistance. GCC can be widely applied as a substitute technique to the EOR for common heavy oil reservoirs similar to Hai 1 block.
