摘要
大庆外围油田葡萄花油层具有单层厚度薄、储量丰度低、储层非均质性严重等特点。通过对三肇地区进行油藏工程分析及数值模拟研究,提出利用水平井开发该类油藏的有效厚度界限、井网形式、水平段长度、水平段方向、注采井排距等开发技术界限进行了优化研究,获得的水平井优化结果符合油田实际,为水平井开发薄层中低渗透油藏提供技术上的参考。
Putaohua reservior of Daqing oilfield has characteristics of thin thichness,ultra-low oil abundance and severe reservoir heterogeneity and so on.According to reservoir engineering analysis and numerical simulation research,the paper optimizes the technical limits of net pay cut off,horizontal pattern,the optimum well length,horizontal wells direction,critical well spacing and so on. The results can accord with the practice.The study of this paper developed a methodology to calculate the optimum horizontal well technical limits.
