胜利油田部分油田、区块属于胶结疏松的常规稠油出砂油藏,油层埋藏浅,出砂严重,随着油田开采时间的延长,地层出砂加剧、防砂难度逐年增加。为了提高这部分油田的开发效果,引进了新型的一次性高压充填防砂工艺,并在应用过程中不断对防砂配套技术、防砂施工工艺进行完善和改进应用,取得了良好的防砂增油效果。
In some oilfields of Shengli Oilfield, the block belongs to conventional heavy oil sands reservoir with loose cementing. The oil reservoirs are shallow buried and sand is serious. With the prolongation of oilfield exploitation time, sand production in the formation is aggravated and the difficulty of sand control increases year by year. In order to enhance the development effect of this part of the oilfield, a new one-time high-pressure sand filling technology has been introduced. In the process of application, sand supporting technology and sand control technology have been improved and applied continuously, and good sand control and oil-enhancing effect has been achieved.
