摘要
东濮凹陷文72块沙三中4-10挥发油油藏具有"六高二低"的特点。其挥发油的化学成份非常接近典型挥发油,体积收缩特点主要受控于地层压力与泡点压力的匹配关系。据此,文章对比分析了文72块挥发油油藏开采初期及目前开采现状,进而指出目前产量下降的根本原因及提高产量和开采效益应该采取的应对措施。论文对国内同类油藏的开发开采具有一定的借鉴意义。
Middle Sha 3 volatile oil pool of wen 72 in Dongpu depression has the features of ＂ six highly, two lowly＂. Volatile oil＇s chemical composition is nearly close to representative volatile oil＇s, and its volume contraction is mainly under control of matching relation with formation pressure and bubbling pressure. According to this, the article has comparative analysis on initial tapping period and currernt status of tapping for volatile oil pool, out the root reasons of the current production rate decline and the furthermore, it points response treatings of improving outputs and tapping benefits. The article has reference on domestic oil pool development and tapping of the same kind in some degree.
