以辛11为代表的多油层强非均质复杂断块油藏,在经过层系重组调整后,在一定程度上减缓了层间干扰。重组后的层系内各小层间因储层本身的地质差异和开发的不均衡,仍然存在层系内的干扰及平面的不均衡现象。本次精细小层地质研究和开发状况评价,实施层系内各个小层物性、含油条带、采出程度、吸水差异整体评价,进行层内水井统一层段整体细分、油井依据含水等差异梯次补孔等,进一步减缓层系内层间干扰。改善层系内小层的平面纵向均衡开发效果,提高多油层强非均质复杂断块油藏的采收率。
Multi-reservoir strong heterogeneous complex fault block reservoirs, represented by Xin 11, mitigated the inter-layer interference to a certain degree after stratified restructuring. Due to the geological differences and the unbalanced development of the reservoirs in the reconstructed strata, the stratification and plane imbalance still exist in the strata. The fine small layer of geological research and development status evaluation, the implementation of the layers of small physical properties, oil bands, the degree of production, water absorption differences in the overall evaluation of the overall well layer unified subdivision, wells based on water and other differences Echelon fill holes, etc., to further reduce the layer inter-layer interference. Improve the development effect of vertical and horizontal plane equilibria of small layers in the strata, and enhance the recovery of strong heterogeneous complex fault block reservoirs in multi-reservoir.
