常规稠油油藏高产井分布规律

Distribution of high-productivity wells in conventional heavy oil reservoir

在陆上常规稠油油藏资料分析的基础上 ,对常规稠油油藏高产井作了定义。以胜利油区某油藏为例 ,分析了影响常规稠油油藏高产井分布的地质和开发因素 ,认为高产井分布主要与油层的储量丰度、地层系数、沉积微相以及钻井工艺技术有关 ;并分析总结了不同含水开发阶段高产井的分布规律。这些研究结果对海上常规稠油油藏开发具有重要的借鉴意义。

A definition of conventional heavy oil reservoir is presented by analyzing a lot of data from onshore heavy oil reservoirs in China. As an example, the geological and developing factors to control high?productivity wells are analyzed for a heavy oil reservoir in Shengli field, and it is concluded that the distribution of high?productivity wells may depends on reserves abundance, formation conductivity,sedimentary microfacies and drilling technology. In addition, the distribution of high?productivity wells during different development periods is analyzed and summarized. All these results may be important to development of conventional heavy oil reservoirs in offshore.
