低油价下提高开发效益做法与效果

Low oil Prices to Improve the Effectiveness of Development Practices and Effects

高含水开发后期,为满足精细开发的需要,在精细构造、沉积微相及动态分析方法的基础上,结合多井评价与流动单元划分建立更加精细的三维地质模型,实现控水稳油。重点开展以下研究工作:一是研究剩余油分布规律,立足三个结构调整,利用注水的产液的综合调整,提高水驱波及面积,提高平面驱油效率;二是加大基础研究及管理工作,依托井组精细评价,挖潜断层高部位剩余油。低油价下投入减少,井组精细研究、精细调整工作的重要性更加突显。因此进一步强化了井组稳升活动的工作机制和内容。

In the late stage of high water-cut development, to meet the needs of fine development, based on the fine structure, sedimentary microfacies and dynamic analysis methods, a more precise three-dimensional geological model was established based on multi-well evaluation and flow unit division, .Focus on the following research work ： First, the study of the remaining oil distribution law, based on three structural adjustments, the use of a comprehensive adjustment of the production of water injection to improve the water flooding and area, improve the efficiency of plane flooding ; the second is to increase basic research and management, Relying on the fine evaluation of the well group, tapping the residual oil in the upper part of the fault.Lower investment in low oil prices, well group of fine research, fine adjustment of the more prominent the importance of the work.We further strengthened the working mechanism and content of the well group stabilization activity.
