东海某气田气藏预测与开发实践

东海某气田气藏主要受构造与岩性控制。分布于地下2200～2800m，发育多套气水系统。其中明月峰组的M1^1与M1^2气藏是常规气藏，也是该气田的主力气藏。钻前通过AVO正演及“亮点”技术预测了M1^1与M1^2气藏的分布范围，发现与构造含气范围不一致；开发井钻后，经新井数据校正，两者匹配较好，从而落实了“亮点”的存在，证实“亮点”技术在该气田进行气藏预测是可靠的。

The Gas Reservoir Prediction and Development in a Gas Field of East China Sea

The gas reservoir of a gas field in East China Sea is mainly controlled by structure and lithology, which is distributed in the ground of 2200～2800m and develops multiple sets of gas--water systems. The M1^1 and M1^2 of Mingyuefeng formation are normal gas reservoirs and also the main ones of the gas field. By AVO forward modeling and Spot tech- nology prediction of M1^1 and M1^2 gas distribution, it is found that M1^1 and M1^2 gas distri- bution is different from the gas area defined by structure. After the drilling of development wells and further corrected by them, the gas area between them becomes harmonious at last. So the spot of the gas field is proved and the gas reservoir prediction by it is reliable.
