【摘要】 由于残留可容纳空间控制着古水流的分布,因此,不整合面之上剥蚀而来的陆源碎屑物主要沿残留可容纳空间发育区向盆地方向搬运,在过路沉积作用面以下的残留可容纳空间发育区保存,因此过路沉积作用面以下的残留可容纳空间发育区成为储集砂体发育较为有利的部位。实践表明,识别残留可容纳空间为开展储集砂体预测提供了线索和思路,在苏里格气田优质储层的预测与气田的高效开发中发挥了作用,沿层序界面之上的残留可容纳空间分布区重新布井获得了成功。更多还原

【Abstract】 The method is provided for the favorable sandy reservoir’s prediction by the recognition of the remained accommodation in this paper. Remained accommodation is the potential area of the geomorphic low near the surface of the sequence boundary during the period of the unconformity formation. The distribution of the paleocurrent is mainly controlled by the remained accommodation, the coarse sediments are transferred along the remained accommodation from the geomorphic high to the basin as the result of truncation, which are maintained in the area of the remained accommodation below the bypassing surface. As a result, the remained accommodation below the bypassing surface is the most favorable place for the high quality reservoirs to develop.The method had played a role in the prediction and high-effectiveness development of Sulige gasfield, and made a success in disposing wells in remained accommodation area over sequence surface. The application results show that the method of the remained accommodation recognition is an effective way for reservoirs prediction.更多还原
