本文总结了华北油区雁翎、龙虎庄等高速开采油田的开发实例,比较具体地叙述了油田的地质特征、开采特点以及开采过程中所进行的措施和效果,在此基础上提出了高速开采可以取得比较高的经济效益,但不利于稳产的认识。对于象雁翎油田这样以裂缝为主的块状底水油藏,在井距比较密的条件下,高速开采对采收率影响不大,主要问题是大幅度地增加了油田产水量,给后期管理带来困难。开发效果的差别主要决定于储层的地质特征及油水粘度比的不同,采用注气是提高这种类型油田采收率的可能方向。
This paper summarizes the development examples of Yanling and Longhuzhuang oilfields in Huabei Oil Region, and particularly describes the geological features, mining features and the measures and effects in the process of mining. On the basis of this, Mining can achieve relatively high economic benefits, but not conducive to stable production. For the fractured bottom water reservoir, such as Yanling Oilfield, where the well spacing is relatively close, high-speed mining has little effect on oil recovery. The main problem is that the production of oil in the field is greatly increased, Post-management difficulties. The difference in development effectiveness depends mainly on the geological characteristics of the reservoir and on the viscosity ratio of oil to water. The use of gas injection is a possible direction to increase oil recovery in this type of oilfield.
