松滋油田红花套组开采技术研究

Research of Production Technique Used in Honghuatao Formation in Songzi Oilfield

通过对松滋油田红花套组构造的分析,发现该区块可能存在两种油藏类型:单一底水油藏和边底水油藏。分别就边底水油藏中的直井及水平井开发应用进行了分析、探讨和比较,优化其中较有优势的直井开采技术,得出了智能开关找堵水和建立水底隔板等技术的使用,有助于提高直井开采采收率,增加油井的无水产油期。

Through analysis of Honghuatao formation in Songzi oilfield, it is found out that the formation is likely to have two types of reservoirs-single bottom water reservoir and edge-bottom water reservoir. This paper has ana- lyzed and compared development and application of straight wells and horizontal wells in edge-bottom water reservoir and through optimizing production technique for straight wells concluded that the use of techniques such as detecting water block with smart switch and setting up separator at water bottom can improve greatly recovery efficiency of straight wells and make the period of their waterless oil production longer.
