摘要
Abstract
The Enping Sag locates in the west of the Zhu I Depression. Petroleum has been found in the sag; however, no industrial breakthrough has been made. Source depression controls the horizontal distribution of petroleum in the study area. Petroleum accumulates around depression and near to source. Due to fault activity and the southward uplifting of source formation, the southern gentle slope is the favorable target for petroleum migration. 3 sets of reservoir and cap combinations have been found in the region, including the Wenchang Formation, the upper Enping Formation, and the Zhujiang-HanjiangFormation, which control the vertical distribution of petroleum. Based on the experiences from failed wells, the accumulation conditions in the area have been pointed out and the accumulation model has been established. The Enping Sag is favorable for petroleum accumulation. The shallow layers in the southern gentle slope and the deep layers in the central fault belt are the most potential targets for exploration in the Enping Sag.关键词
