东海平湖构造带地质构造特征及含油气条件

Geological Features and Hydrocarbon-bearing Condition of the PingHu Tectonic Belt,the East China Sea

平湖构造带是东海油气勘探与开发的重点之一 ,主体部位已完成了 7块 3D地震勘探区块 ,钻井 1 3口 ,先后发现了平湖等四个油气田 ,为了深入了解平湖构造带的地质构造特征及含油气条件 ,掌握油气富集规律 ,文章在历年油气勘探和科研成果的基础上 ,结合最新的 3D地震构造解释成果 ,特别是对原来发现的局部构造进行了重新认识 ,进一步掌握了各区块之间的地质构造特征 ,综合研究认为 :平中与平北各油气田之间的构造圈闭成藏条件良好 ,预测为有利的含油气构造 ,可作为今后的钻探的目标 ;

The PingHu Tectonic Belt is one of the key point of hydrocarbon exploration and development in the East China Sea,3D seismic exploration of 7 blocks have been finished,13 well drilled and 4 fields including the PingHu field discovered in the main body of the area.Combined with the new 3D interpretation results,this paper re-recognized the early discovered part structures.Comprehensive analysis indicated that the reservoir condition is good in the trap among the PingZhong and PingBei fields,which can be predicted as the beneficial hydrocarbon-bearing structures for future drilling,and the PingNan area may be listed in new group of exploration.
