【摘要】 雷11块构造上处于辽河盆地西部凹陷西斜坡北段,与高升油田高二三区南端高18块相邻,开采层系为沙四段杜家台油层和沙三段莲花油层。随着雷11块莲花油层开采规模的逐步增大,暴露出了该油藏构造破碎、岩性变化大、油水关系复杂等问题,而这些问题的存在直接影响了油藏下一步开发调整的进程。通过该论文的研究,对雷11块的储层特征、构造特征、沉积特征和以及低阻油层的形成原因等有了重要认识,搞清雷11块莲花油层的油藏内幕,找出了形成本地区低电阻油层的形成原因,取得了大量动静态成果,对该块的油层改造、注采井网调整以及下一步产能部署具有重要的指导作用。雷11块油藏特征复杂,通过本论文的研究,以现有的三维地震、测井、试油试采及油田动态监测等资料为基础,综合运用地震学、地质学、测井学以及油藏工程学等理论,以落实油藏构造和储层特征为主线,搞清该区块油藏特征、油水层分布、产能分布等情况。对不断开展低阻油藏精细描述,深化细化油藏地质认识以及保持雷家地区产量稳定具有重要意义。更多还原

【Abstract】 The conformation of Lei11 Block lies the north segment of west incline of west hollow of Liaohe Basin. Link with the south of Gao18 Block of Gao 2 3 Area of Gaosheng Oil Field. Exploitation layers are the Dujiatai reseviors of Sha 4 segment and the Lianhua reserviors of Sha 3 segment. Along with the augmentation of exploitation scale in Lianhua Layers of Lei11 Block. Exposes the questions as reservoir conformation is broken up, lithology change is large and the relation between oil and water is complicated. And the questions will influence the next exploitation and adjustment course.From the paper, we can have some important results about the reservoir feature, conformation feature, sediment feature and the forming cause of low resistance layers in Lei18 Block. We have known the reservoir situation of Lianhua layer in Lei11 Block and have found the forming cause of low resistance layers in this area. And get a lot of static behavior results. And will have some important direction to the layer reconstruction, the adjustment of the nets between affusion wells and oil wells and the next yield plan.The reservoir feature in Lei11 block is complicated. From the paper, basing on the present dates from 3-D seismics, well-logging, well-testing and oil-field change surveillance. We synthetically use the theory of seimics, geology, logging, reservoir engineering. As the primary goal with finding out reservoir conformation and layer feature. We know carefully the things about reservoir feature, oil and water layers distribution and yield distribution. This will have important part for careful description of low resistance reservoir, drastically knowing the reservoir situation and keeping the yield of Leijia area steady.更多还原
