摘　　要：TⅡ油组是解放渠东油田的主力产层,平均孔隙度23.6%,平均渗透率416 m D,储集空间以粒间孔、粒间溶孔为主,目前TⅡ油组已处于高含水低效开发后期,为了延缓产量递减、实现稳油控水,通过应用TⅡ油组提液增油技术,将高含水油藏采用换大泵提液,实现了解放渠东油田三口高含水油井稳产,得出了提液增油技术的地质条件是物性较好的中高孔、高渗油藏,压力保持水平达到80%以上且外围存在广阔的水源,油层产水类型以边水为主,总结了提液增油的最佳时机是含水率达到90%以上。Jiefangqudong oil is a short axis anticline oil and gas in Tarim Oilfield in Tabei Uplift in Lunnan Qianshan anticline on the southeast slope of large reservoirs. TII group is the main oil layer in Jiefangqudong oil production,and the average porosity is 23. 6%,the average penetration rate of416 m D. The reservoir space is mainly intergranular pore,and the intergranular dissolution pore the main part. At present,TII oil group has been in the late period of high water cut and low efficiency.To delay production decline and stabilize oil and water,we use the application of T oil group in-creased oil extract technology,which will be in high water cut reservoir with large pump replacement extract. This helped to realize three high water cut oil production in Jiefangqudong oilfield. The geological conditions of increasing oil extract technology is of high porosity and high permeability reservoir is better; the pressure to maintain the level of more than 80% and the periphery has the wide water; the reservoir water is in edge water. We summed up the best time to extract oil is when the moisture content is more than 90%.
