文72东油藏滚动勘探开发高效做法

The High Eeffective Methods of Progressive Exploration and Development in Wen72D Reservoir

复杂断块油藏勘探和开发没有明显的界限 ,其开发过程实际上是详探的延续 ,通过几年来的滚动勘探研究 ,相继发现、落实了徐楼断层下盘沙三上 8砂组、沙三上 9～ 1 0砂组和沙三中 1～ 2砂组油气层 ,新增动用石油地质储量 1 74× 1 0 4 t,天然气地质储量 4 3× 1 0 8m3,取得了显著的滚动开发效果 ,实现滚动勘探开发一体化 ,为文南油田继续保持稳产提供了储量接替 ,同时也为其它复杂断块油藏滚动勘探开发提供了借鉴经验。

There is not obvious difference between exploration and development in the complicated fault block reservoir.The development process of reservoir is in fact the extension of detail exploration.The Wen72D reservoir under Xulou fault was found through a few year exploration research.Wen72D reservoir including Es 3s 8,Es 3s 9-10 and Es 3z 1-2 formations was found due to remarkable effect of combination detail exploration and development.Its oil reserves is about 1740 thousand tons and gas reserves is about 0.43 billion cubic meters.The discovery of Wen72D reservoir not only provided a good reserves to Wennan oilfield,but also practiced a method of combination of exploration and development,which has suitable practicing possibility in the other oil fields.
