摘要
针对老河口油田桩106块注水开发单元储层非均质性严重、动用程度差、不均匀的问题,研制了一种新型复合化学驱油剂ZXDS-1,进行了驱油剂配方的筛选及性能评价,并在桩106-19-X16井组试验,措施后单元日增油22.8t,截至2007年2月底,已累计增油4177t,取得了较好的经济效益。
In allusion to the problems of severe heterogeneity, poor and uneven producing extent in water flooding unit of Block Zhuang 16 in Laohekou Oilfield, a new composite chemical oil displacement agent ZXDS-1 was developed, the formula of displacement agent was chosen, its property was evaluated and tested in Well Zhuang 106-19-X16. After stimulation daily unit oil increment was 22.8t, by the end of Feb. 2007, accumulated oil increment was 4177t. Better economic benefit is achieved.
