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。
Dongpu Depression Wen 72 sand three 4-10 volatile oil reservoir with “six high and two low ” characteristics. The chemical composition of its volatile oil is very close to the typical volatile oil, volume shrinkage characteristics are mainly controlled by the formation pressure and bubble point pressure matching. Accordingly, the article compares and analyzes the initial exploitation status of the 72 reservoirs of volatile oil reservoirs and then points out the current reasons for the decline of output and the countermeasures that should be taken to improve the yield and exploitation benefits. The thesis has certain reference significance for the exploitation of similar reservoirs in China.
