摘 要:
文70断裂带位于东濮凹陷中央隆起带文留构造带南部,油藏受文东断层、文70断层和文147断层3条东倾的断层控制,为东倾的断层和一系列西倾的断层形成的断块。断层切割关系复杂,造成断层组合多解性强;另外由于沙三中亚段4~8砂组钻遇井少,构造落实程度低。按照"滚动勘探、油藏评价、开发调整、注采配套"4位一体的勘探开发思路,运用精细地层划分与对比、RFT测试资料、HDT测井资料和三维地震解释等新技术和新方法,在强调整体解释的基础上,重新梳理文70断裂带各断层的空间展布及组合关系,落实了构造形态和圈闭特征。该精细研究深化了对复杂断块油田油气成藏规律的认识,对断裂带滚动勘探开发起到了很好的指导作用。

摘 要:
Wen-70 Fault Zone is located in the south of Wenliu Structural Belt of central uplift zone in Dongpu Depression,which is a faulted block formed by east inclined fault and a series of west inclined faults and where reservoirs are controlled by three east inclined faults as Wendong,Wen-70 and Wen-147.Due to complex and mutual cutting,there also can be lots of fault interpretation schemes.Additionally for few sand groups 4~8of S3 zwhich are encountered by drilling,structure is confirmed in low-level.In this paper,through all kinds of new methods and technologies,such as detailed stratigraphic division and correlation,RFT test data,HDT logging data and 3Dseismic interpretation etc.,and on the base of overall interpretation,steric distribution and cutting relation of faults in Wen-70 Fault Zone are emphatically analyzed,structural shapes and trap characteristics are confirmed.This detailed study deepenes recognization of reservoir rules in complex block oilfields,and can guide rolling exploration and development in Wen-70 Fault Zone.
