珠江口盆地东部底水油藏的开采速度是很高的.在高速开采条件下,如何保证有较高的采收率是重要的研究课题.本文从分析东部底水油藏特征入手,阐述了底水油藏具备高产能的诸多有利条件,用数值模拟方法研究了主要砂岩底水油藏的采油速度与采收率的关系,并对HZ26-1油田底水油藏M-10层提高采收率方向作了典型分析.总的看法是,东部底水油藏由于其特定的地质特点,高速开采对油藏的最终采收率无不利影响.最后对如何提高采收率提出了几点看法.
The bottom water reservoir in the east of Pearl River Mouth Basin is very high in exploitation speed.It is an important research topic how to ensure a high recovery rate under high-speed mining conditions.Based on the analysis of the characteristics of eastern bottom water reservoir, The bottom water reservoir has many favorable conditions for high productivity. The relationship between oil recovery rate and oil recovery rate of the main sandstone bottom water reservoir was studied by numerical simulation method, and the M-10 layer of bottom water reservoir of HZ26-1 oilfield was enhanced The general view is that the eastern bottom water reservoir has no adverse effect on the ultimate recovery of the reservoir due to its specific geological characteristics and high-speed mining.Finally, some suggestions are put forward on how to improve the recovery rate view.
