胜坨油田普通稠油油藏聚合物驱试验效果评价

Evaluation of Polymerflooding Pilot in Ordinary Heavy Oil Reservoirs in Shengtuo Oilfield

以胜坨油田胜一区注聚先导试验项目为例,对聚合物驱的高温高盐普通稠油油藏的见效特点进行了分析评价,采用'增量法'通过计算增量效益和费用,来对聚合物驱项目的经济效益进行分析.评价结果显示,注聚先导试验经济净效益3.95×108元,为类似普稠油田高含水期开展聚合物驱提供了依据.

Taking the polymerflooding pilot project in Shengl Block in Shengtuo oilfield as an example, this paper analyzes the response characteristics of polymerflooding in ordinary heavy oil reservoirs with high temperature and high salinity. 'Incremental method' is used to analyze the economic benefits of polymerflooding projects through calculating the incremental benefits and costs. Evaluation results reveal that the pilot achieves net economic benefits of 3. 95 × 108 RMB and provides a basis for performing polymerflooding in similar ordinary heavy oilfields at high water cut stage of development.
