摘要
Based on the present exploration situation,we consider that the lithologic reservoir should be the next exploration target in the slope area of Qikou sag. According to slope location,formation feature and exhibition feature, the slope area of Qikou sag is divided into basin fringe fault abrupt slope, break gentle slope, fault terrace gentle slope and fault slope. Based on accumulation model of petroleum accumulation in the Qikou depression, the authors discuss the pattern of sand distribution, dredge system and thermal evolution of source rock, and then concluded the distributed model of lithologic reservoir in the slope area. This model is testified by exploration practice, suggesting that the exploration of lithologic reservoir in the slope area of Qikou sag would be better.
