砂砾岩特稠油油藏边水综合治理技术研究及实践

THE RESEARCH AND PRACTICE OF THE EDGE WATER COMPREHENSIVE MANAGEMENT TECHNOLOGY IN THE GLUTENITE SUPER-HEAVY-OIL RESERVOIR

乐安油田南区自 1991年投入开发 ,至 1996年底边水侵入日趋严重。近几年来通过开展同位素示踪剂监测边水侵入规律的研究、边部提液降压开采、边部提堵结合开采、边部全面封堵技术等现场实践 ,积极有效地控制了边水的大规模入侵 ,为在乐安油田大面积推广边水综合治理技术奠定了良好的理论和实践基础 ,对具有较强边水的砂砾岩特稠油油藏的开采具有显著的指导意义。

The southern block of the LeAn oilfield was exploited from 1991.By the end of 1996,the invasion condition of the edge water became worse and worse. In recent years,the research of the edge water invasion law is done by the radioisotope tracer,decompressional exploitation in the margin,producing by pumping and plugging in the border and the practice of plugging in all margin region,the massive invasion of the edge water had been controled effectively.All these had been built a nice base in theory and practice for spreading edge water comprehensive management technology widely in the LeAn oilfield.It has an important directive significance for the glutenite super-heavy-oil reservoir's exploration.
