【摘要】：马南地区位于兴隆台油田南端,其勘探开发工作陆陆续续一直没有间断。在2004年以后的勘探开发中,效果不理想,目前仍处于详探阶段。勘探开发历程一方面说明随着该区域勘探开发程度越来越高,寻找有利目标的难度越来越大,另一方面也说明对区域地质认识还有待进一步加强。马南地区兴隆台油层存在着构造认识不清、储层分布、沉积状况不明等诸多地质模型认识问题,目前区块井网为探井井网,不能实现有效开发。现有的油藏描述己不能满足该区块开发后期剩余油挖潜,急需针对储层的地震地质综合精细描述,精细刻画断棱、断面以及研究构造样式,为断块开发后期剩余油研究及开发部署井网调整提供地震技术支撑。本文为深入分析剩余油分布特征,提供研究地震地质相关依据,将针对研究区目的层段开展相控储层预测。本次构造解释所应用的地震资料是重新采集并处理过的三维地震资料。通过三维地震精细解释与三维地震储层预测对马南地区重新进行储层预测。本论文在构造精细解释基础上,进行构造特征再认识、砂体分布预测和综合地质研究,寻找有利目标并提出井位建议。通过本次研究,对工区内在地层划分与对比、储层沉积、造特征、在油水分布特征等方面取得了一系列成果和认识,完成多张成果图件。通过三维精细构造解释,落实了本区的构造特征,理清了断裂系统展布特征,构造解释成果符合区域构造地质沉积规律,能够合理解释完钻井的地层发育特征以及油水生产特征。从构造解释成果图分析,本区沙一二段地层构造特征表现出较好的继承性。通过地质综合研究,本区以构造油气藏为主,但也存在局部发育的岩性油气藏。虽然工区经过近40年的勘探与开发,构造位置明显的地方已勘探相对成熟,但进一步分析表明,局部微幅度构造和局部的岩性油藏是下步调整挖潜的有利方向。
[Abstract]:The Mannan area is located at the southern end of Xinglongtai Oilfield, and its exploration and development work has not been interrupted. In the exploration and development after 2004, the effect is not ideal, and it is still in the stage of exploration. On the one hand, the exploration and development process shows that with the increasing degree of exploration and development in the region, it is more and more difficult to find favorable targets, on the other hand, it also shows that the understanding of regional geology needs to be further strengthened. There are many geological model recognition problems in Xinglongtai oil reservoir in Manan area, such as unclear understanding of structure, reservoir distribution, and unclear sedimentary condition, etc. At present, the block well pattern is a pattern of exploration wells, which can not be developed effectively. The existing reservoir description can no longer meet the potential of remaining oil in the later stage of development of the block. It provides seismic technical support for the research of remaining oil and the adjustment of well pattern in the later stage of fault block development. In order to analyze the distribution characteristics of remaining oil and provide the basis for the study of seismic geology, the facies controlled reservoir prediction will be carried out for the target formation in the study area. The seismic data used in this structural interpretation are three-dimensional seismic data collected and processed. Three dimensional seismic fine interpretation and three dimensional seismic reservoir prediction are used to predict the reservoir in Manan area. On the basis of fine interpretation of the structure, this paper makes re-recognition of structural characteristics, prediction of sand body distribution and comprehensive geological study, seeks for favorable targets and puts forward suggestions for well location. Through this study, a series of achievements and understandings have been obtained in the areas of internal stratigraphic division and correlation, reservoir deposition, formation characteristics, oil and water distribution characteristics, and many achievement maps have been completed. Through three dimensional fine structural interpretation, the structural characteristics of this area are carried out, and the distribution characteristics of fault system are clarified. The results of structural interpretation accord with the regularity of regional tectonic geological deposit. Can reasonably explain the formation development characteristics and oil-water production characteristics after drilling. Based on the analysis of structural interpretation results, the stratigraphic characteristics of the first and second member of this area show good inheritance. Through the comprehensive geological study, this area is dominated by structural oil and gas reservoirs, but there are also locally developed lithologic reservoirs. After nearly 40 years of exploration and development in the working area, the location of the structure is relatively mature, but further analysis shows that the local micro-amplitude structure and local lithologic reservoir are the favorable direction for the next step adjustment.
