摘 要: | 在西湖凹陷区域研究新认识的基础上,通过构造发展史、排烃史、成藏期痕检资料、岩相组合等资料,重新认识西湖凹陷新生代盆地发展过程中圈闭(地层、构造)形成时间、烃源岩排烃时间、已发现油气藏成藏时间、多种疏导方式及形成时间以及对油气藏的破坏事件发生时间,推演西湖凹陷成藏史发展过程。结合新的油气成藏认识,提出今后工作方向的几点思考意见。

Abstract: | Based on new results of regional study, play-evolving process of Xihu Sag was interpreted by means of structure histroy, oil/gas expulsion history, trace test of play-forming period and litho-facies data, and the occurrence time of a series of play-forming events was rediscovered such as trap (lithologic and structural traps) forming time, oil/gas expulsive periods, play-forming periods, oil/gas passage forming time and destructive effects, and the play developing process of Xihu Sag was analyzed. Finally, new point of view of play-forming was put forward in Xihu Sag. |
