【摘要】：欢17块位于辽宁省锦州市和盘锦市境内,南邻渤海湾。构造上位于辽河断陷盆地西部凹陷西斜坡的西南部,北靠锦99块,南邻锦27块,东接锦4块,构造面积约4km2。该块目前存在的主要问题是已上报含油面积井区内油井因套坏、高含水等原因全部停产,而断块其余区域构造、储层认识不是很清楚。为提高该断块开发效果,有必要开展研究,深化地质认识,搞清剩余油分布规律,重点是针对井区东部进行构造、储量再落实,提出下步开发对策。在借鉴前人研究成果的基础上,以大量丰富的三维地震、钻井、录井、测井、岩心、试油试采、开发动态、油水分析化验等资料为基础,充分利用地质、地球物理、开发动态资料,发挥多学科联合攻关的优势,以油气地质理论为基础,将层序地层学、沉积学、油气地质、地球物理学等多学科的新理论、新技术和新方法充分运用到研究中,搞清区块内构造特征、砂体分布、储层特征、流体特征、油水关系、压力系统等,对注水开发效果进行评价,找出区块开发调整的方向及潜力,改善区块开发效果。通过对区块构造、储层及油藏特征的再认识,并针对区块目前存在的主要问题,对两个次级断块提出了调整部署意见,计划实施调整井2口,并对目前现有的3口老井实施补孔试采措施,进一步完善注采井网,提高储量动用程度。
[Abstract]:Huan 17 block located in Jinzhou and Panjin City, Liaoning Province, south Bohai Bay. It is located in the southwest of the west slope of the western depression of Liaohe fault depression basin. It is located on the north of Jin 99 block, the south neighbor brocade block 27, and the east Jin 4 block, with a tectonic area of about 4 km ~ 2. At present, the main problem in this block is that the oil wells in the oil-bearing area well area have been reported to have stopped production due to casing failure, high water cut and other reasons, while the structure of the rest of the fault block is not very clear about the reservoir. In order to improve the development effect of the fault block, it is necessary to carry out research, deepen geological understanding, and find out the distribution law of remaining oil. The emphasis is to carry out structure and reserve re-implementation in the east of the well area, and put forward the next development countermeasures. On the basis of reference to the previous research results, and on the basis of abundant 3D seismic, drilling, logging, core, oil testing and production testing, development dynamics, oil and water analysis and laboratory tests, etc., to make full use of geology, geophysics, etc. Based on the theory of oil and gas geology, the new theories, techniques and methods of sequence stratigraphy, sedimentology, oil and gas geology and geophysics are fully applied to the research. In order to evaluate the effect of water injection development and find out the direction and potential of block development adjustment and improve the development effect of block, it is clear that the structural characteristics, sand body distribution, reservoir characteristics, fluid characteristics, oil-water relationship, pressure system and so on. Based on the recognition of the block structure, reservoir and reservoir characteristics, and in view of the main problems existing in the block at present, the paper puts forward some suggestions for the adjustment and deployment of the two secondary fault blocks, and plans to carry out 2 adjustment wells. At present, three existing old wells are tested by hole filling to further improve the injection-production pattern and increase the production degree of reserves.
