摘　　要：曙三区杜家台油层自1975年开发以来,已经历40多年的开发,目前油水关系十分复杂,如何提高油田开发效果已成为急需解决的问题。杜家台油层组的储层主要为-套中—细碎屑的扇三角洲前缘沉积砂体。位于扇三角洲前缘的油层尽管一直作为主力油层开发,综合含水逐渐升高,但剩余油潜力仍然很大。这些剩余油受控于油层内部渗流差异和渗流屏障,是下一步继续部署的重要目标。然而,常规的油藏描述难于表征厚油层内部的非均质性,因而难以预测储层内部非均质性控制的剩余油的分布。储层构型正是针对储层内部非均质性进行深化研究的领域,对于碎屑岩储层剩余油分布预测及挖潜具有至关重要的意义。The Dujiatai reservoir in Shushan District has been under development for more than 40 years since it was developed in 1975.At present, the relationship between oil and water is very complicated.How to improve the effect of oilfield development has become an urgent problem to be solved.The reservoir of the Dujiatai Formation in this area is mainly composed of medium-fine crust fan delta front sedimentary sand body.Although the oil layer located at the front of the fan delta has been developed as the main oil reservoir and the integrated water cut gradually increases, the residual oil potential remains high.Controlled by differences in seepage and seepage barriers within the reservoir, these remaining oils are important targets for continued deployment in the next step.However, the conventional reservoir description is difficult to characterize the heterogeneity of the interior of thick reservoirs, making it difficult to predict the distribution of residual oil controlled by heterogeneity within the reservoir.Reservoir configuration is precisely the field of in- depth study of reservoir heterogeneity, which is of crucial significance for the prediction and exploration of remaining oil distribution in elastic reservoirs.
