红连边底水油藏高效开发实践与认识

Practice and Knowledge on High Efficiency Development for Edge and Bottom Water Reservoir of Hong Lian

针对小型块状边底水油藏特征,编制了适合油藏特点的开发方案,论证了油田合理开发技术政策界限,在开发实践中不断加深认识,合理调整,探索出低含水期控制液量、中含水期油水同采、高含水期老井侧钻、关井压锥等有效防治和治理底水锥进的新方法,形成了小型边底水油田开发的成熟技术,实现了油田高速高效开发,为今后同类型油田的开发提供了可借鉴经验。

As for properties of small block edge and bottom water reservoir, development scheme adapted to reservoir property is worked out; reasonable development technical boundary has been demonstrated. During development, much more understanding is obtained and reasonable adjustment is underway. A new method to effectively prevent and solve bottom water coning, which is controlling liquid volume at low water cut period, producing oil and water simultaneously at middle water cut period, sidetrack drilling for old well at high water cut period and temporarily shutting down to avoid water coning, has been exploited. Mature technique to develop small scale edge and bottom water oilfield has been formed, high speed and effective development for oilfield has been realized, which provide reference experiences for developing the same reservoir for the future.
