低渗透油藏二氧化碳混相驱超前注气实验研究——以吉林油田黑79区块为例
Experimental research on CO2 miscible flooding by advanced gas injection in low permeability reservoir-case of H79 block, Jilin oilfield
摘要
Abstract
In order to enhance the oil recovery in low permeability reservoir by CO2 miscible flooding through advanced gas injection, its feasibility is tested in laboratory. The minimum miscible pressure is determined by micro-tubes tests;the laboratory result of CO2 miscible flooding by advanced gas injection with long core physical simulation device is researched and the result is compared with that of synchronous gas injection and water flooding. The ultimate recovery of CO2 miscible flooding by advanced gas injectionis 77. 03% , synchronous gas injection is 73.09% and water flooding is 56.47%. Results show that, since the advanced gas injection can increase the formation pressure and energy, the oil's viscosity is reduced and its mobility is increased because gas injected in advance is contacted with oil, recovery of advanced gas flooding is higher than that of synchronous gas injection and water flooding.关键词
