自生气采油技术是近年来发展的一种新技术。该技术是向储层中注入自生气体药剂溶液,使其在油藏条件下发生化学反应、释放出自生气体。产生的气体溶于油相可降低原油黏度,联通地层孔隙,诱导非动用区流体流出,提高采出率,且反应产生的热量对沥青质,胶质等有机质具有分散,溶解的作用,能有效解除有机物堵塞,从而提高单井产能。研制了一种新型层内自生气体系。试验结果表明:该体系具有生气量大、放热量大的特点。
Self-angry oil recovery technology is a new technology developed in recent years. The technology is to inject self-generated gas solution into reservoirs to make it react chemically under reservoir conditions to release autogenous gas. The gas dissolved in the oil phase can reduce the viscosity of the crude oil, connect the pores of the formation and induce the fluid outflow in the non-use zone to increase the recovery rate, and the heat generated by the reaction has the effect of dispersing and dissolving the asphaltenes, gums and other organic matters and is effective Solve the blockage of organic matter, thereby improving single well productivity. A new type of in-layer self-generated gas system has been developed. The test results show that the system has the features of large gas generation and large heat release.
