| 摘 要： | 沈161块S23亚段储层属于扇三角洲分流平原亚相沉积。各个沉积相的储层物性差异比较大,砂体横向连续性较差,其非均质性十分显著。垂直和水平的油层没有充分利用,回收率只有13%。油田开发仍具有潜力。文章阐明储层物性特征,认真研究储层非均质性,为下一步指导生产做好准备。

| Abstract: | The S23 reservoir in Shen 161 block belongs to fan delta distributary plain subfacies deposit. There are great differences in physical property of each sedimentary facies reservoir with poor lateral continuity of sand body and obvious heterogeneity. The vertical and horizontal oil layers are not fully utilized, and the oil recovery is only 13%. Further development of oil field still has potential. In this paper, we would clarify the physical properties of the reservoir and conduct carefully study on the reservoir heterogeneity, so as to do a good preparation for guiding future production. |
