杏二中三元复合驱工业性矿场试验

大庆油田三元复合驱技术经过多年的室内和矿场试验研究,成功地完成了5个三元复合驱小型矿场试验.试验结果证明：三元复合驱技术可以比水驱提高采收率20%以上.1998年大庆油田开展了世界上第一个三元复合驱工业性试验,进一步验证了三元复合驱在大井距（250m）多井组（17注27采,9口中心采油井）多油层（PI1-3砂岩组）条件下的驱油效果,油水井的动态变化规律,注采工艺技术及采出液处理技术,为大庆油田三元复合驱技术大规模推广应用提供理论和实践依据.介绍了试验区的进展情况,油水井的动态反应,采出井见碱、表活剂、聚合物及乳化情况.结合精细地质研究重点阐述了三元复合驱工业性试验区的驱油效果,总结了油田发育上的差异对驱油效果的影响,并与小型矿场试验区对比,分析总结了工业性试验区含水变化规律.

ASP-FLOODING INDUSTRIAL MINE TRIAL IN XING ER ZHONG

By several years indoor tackling key problem(1) and mine-field experimentation,ASP flooding technique has successfully completed five minitype mine-fields trials in Daqing oil field..The test results show:ASP flooding technique may increased more 20% than water flooding in recovery ratio.(2)(3)(4)The first industrial ASP flooding mine-field in world started in Daqing oil field ,and tested the driving oil effect of under the condition of big well distance(250m),excessive well groups(17pours 27extraction,9 central oil extraction wells),much oil lays(PII-3gristone set)and oil-water well of dynamic change law,the extraction pour technologies and the disposing technique on the collection liquor,which supplied the gist of theory and practise of ASP flooding technique in Daqing oil-field.This paper introduces the condition of experimenation field,the dynamic reaction of oil-water well,the extraction effect may be seen from ASP and emulsification condition,furthmore,with the fine geology research described the industrial driving oil effect of ASP flooding.The variety of oil field development influence to the driving oil effect is summed up.The minitype mine-field trial is compared.and summerizing the law of industrial trial content water area is analyzed.
