气顶油环开发成功的关键在于防止气窜、合理利用气顶弹性能量提高油环采收率，而狭长气顶油环要做到这一点非常困难。卫2块就是这样一个典型区块，其南部和北部采用了不同的开发方式，所达到的开发效果也不同，但都未能成功地避免气窜，开发效果不理想。文内通过对其开发实践的总结分析，对此类油气藏的合理开发方式进行了探讨。
The key to successful development of gas capped oil ring is to prevent gas channeling, make rational use of gas cap elastic energy and improve oil recovery, and it is very difficult to achieve this. Wei 2 block is such a typical block, which uses different development methods in the southern and northern parts of the country. The development effects achieved are also different. However, they all failed to avoid gas channeling successfully and the development results were not satisfactory. Through the analysis of its development practices, this paper discusses the reasonable development of such reservoirs.
