胜利油田分层注水工艺技术及发展建议

New Progress of Separate Layer Water Injection Technology in Shengli Oilfield

注水工艺技术在胜利油田的开发中起到关键作用。结合胜利油田的油藏特征,介绍了近几年来开发的分层注水技术,主要包括高温深井分层注水技术、分层防砂分层注水一体化工艺技术、防返吐分层注水技术、测调一体化分层注水技术等4项工艺技术在现场的应用情况。指出其存在的问题,并对分层注水工艺技术的发展提出了建议。

According to the reservoir characteristics and water flooding situation in Shengli Oilfield,the status of process technology of separate layer water injection were summarized.And,the new progress of separate layer water injection technology in recent years was introduced in detail,including the field application of 4techniques such as high temperature deep layer water injection technology,layered sand and layered water injection integration technology,anti-flowback layered water injection technology and measuring and adjusting integration layer water injection technology.The further development of separate layer water injection technology was prospected according to the demand of Shengli oilfield.
