摘要
为了明确"硬连接"断层圈闭识别及形成时期评价方法,以三维地震为基础,结合断层形成演化历史和断层位移分布规律,探讨"硬连接"断层圈闭的识别及其形成时期的定量表征方法,并将该方法应用在文安斜坡王仙庄断层。研究结果表明:王仙庄断层共发育7个"硬连接"断层圈闭,其中①、③、④、⑤号圈闭在油气成藏前期已经形成,能够有效的聚集油气,与目前油气分布吻合,表明该方法对于"硬连接"断层圈闭发育部位及形成时期的预测是可行的,对于指导油气勘探具有重要理论和实际意义。
The "hard-connection" fault trap identification and formation period evaluation methods were determined based on 3D seismic data.The identification of "hard-connection" and quantitative characterization of formation period were discussed by combining with the fault evolution history and fault displacement distribution patterns.This method was applied to the Wangxianzhuang Fault in Wen'an Slope.Research indicates that there are 7 "hard-connection" fault traps in the Wangxianzhuang Fault.The ①,③,④ and ⑤ traps developed before the hydrocarbon accumulation,which could effectively accumulate hydrocarbon.The prediction is consistent with the current hydrocarbon distribution,which indicates the feasibility to predict the "hard-connection" fault trap and formation period and could provide certain theoretical and practical guidance for the hydrocarbon exploration.
