堵水调剖技术作为胜坨油田水驱开发后期提高采收率的一项主导技术,从“七五”开始起步,到“十五”末已形成了较大的矿场应用规模,平均年施工120口井,平均年增油4.5x104t以上,老区自然递减得到一定控制,为减缓油田自然递减、保持老油田稳产起到了至关重要的作用。本文总结了“十五”期间胜坨油田提高堵水调剖配套技术开发效果的主要对策及取得的效果,同时对胜坨油田进一步提高水驱开发效果提出了工作方向和工作安排。
Water blocking profile control technology as the Shengtuo oilfield water flooding late development to enhance oil recovery of a leading technology, starting from the “seven five ” began to “fifteen ” has formed a larger mining applications Scale, the average annual construction of 120 wells, the average annual oil 4.5x104t or more, the natural decline in old areas have been controlled, in order to slow down the natural decline of oil fields, to maintain stable production in the old oil plays a crucial role. This paper summarizes the main countermeasures and results obtained in Shengtuo oilfield during the “Tenth Five-Year Plan” period to improve the effect of water plugging and profile control technology. At the same time, the work direction and working arrangement are proposed for further improving the waterflood development effect in Shengtuo Oilfield.
