渤海海域428东潜山结构特征及勘探潜力分析
|
摘要
428东潜山勘探历史悠久,但一直存在地层对比困难、地层展布及内幕结构认识不清等问题。利用新处理的三维地震资料,并且系统梳理钻井资料,进行了潜山内幕界面标定及反射波组对比,分析了潜山内幕结构并探讨了其勘探潜力。研究结果表明:428东潜山残留4套地层,其中二叠系全区分布,寒武系只分布于潜山东部,潜山基底为元古宙花岗岩;潜山内幕具有不对称性,东部为三层结构,西部为两层结构,整体上为双断地垒型潜山;同时428东潜山油源条件优越,潜山内幕寒武系未钻圈闭极具勘探价值,同时元古宇也值得关注,储层研究将是下一步工作的重点。
Although 428 East buried hill has been explored for many years,misunderstanding still exists about the recognition of stratigraphic correlation,strata distribution and inner structure. Based on the use of newly processed 3 D seismic data,and systematical analysis of drilling data, this study calibrated the internal seismic reflection interface,compared the seismic reflected wave group, and analysed the inner structure of buried hill and the exploration potential.The results show that there are four sets residual strata. Among these residual strata,the Permian is developed throughout the buried hill, the Cambrian is only distributed in the east of buried hill, and the Proterozoic is the basement of the buried hill.The inner structure is asymmetric, with the east of buried hill of three-layer structure and the west of two-layer structure. The whole structure is characterized by double-faulted horst buried hill. The oil source condition of 428 East buried hill is very excellent, and the absence of drilling traps of Cambrian offers higher exploration value. The paper suggests that, the Proterozoic in the area should deserve attention and future focus should be on the reservoir study.
