摘要/Abstract

摘要： 孤东油田经过10 多年的强注强采,目前主力开发单元含水率已高达95%左右,为了实现降水增油目的,从1994年起在该油田经过了历时5年的聚合物驱油工业性矿场实验。针对油田构造简单,油层单一、非均质性强,油层胶结疏松、物性好,原油粘度高,地层水矿化度高等特点,在室内试验和数据模拟的基础上,设计了二级段塞注入方案。方案实施后取得明显效果:油井含水率平均下降了5.6%,日增产原油326t,预计最终可提高采收率6.5%,取得了显著的经济效益。在实验中也出现了一些问题,采取相应措施后都得到了解决。为胜利油田开展大规模聚合物驱展示了美好前景。

Abstract: In Gudong oilfield, after enhanced water injection and enhanced production over ten years, the water cut of main development units has risen as high as 95%. In order to reduce water cut and increase the oil output, a polymer flood pilot experiment in industrial scale has been carried out in the field. for five years since 1994. In view of characteristics of the oilfield such as the relatively simple structure, the unique pay zone, high heterogeneity, loose cementation of pay zone, good lithophysic properties, high viscosity of crude oil, high salinity of formation water, etc., a two-stage plug injection plan has been designed on the basis of laboratory study and numerical simulation. After inplementation, the plan obtained evident results: the water cut of oil wells decreased by 5.6% in average, oil production rate increases by 326 tons per day, and it is expected total ultimate recovery may increased by 6.5%, so the economic benefit is significant. All problems which occurred during the experiment are settled by adopting corresponding measures. The successful pilot experiment has shown bright future for larger scale application of polymer flood in shengli oilfield.
