义和庄地区潜山内幕构造演化特征及其控藏作用
Tectonic evolution characteristics of inner buried hills in Yihezhuang area and its controlling effect on the hydrocarbon accumulation
摘要
Abstract
Tectonic evolution is complicated and its effect on hydrocarbon accumulation is unclear for inner buried hills in Yihezhuang area of Jiyang depression,which is restricting oil and gas exploration in this area.To solve this problem,tectonic evolution characteristics of the inner buried hills was analyzed in Yihezhuang area based on data of seismic,logging,lithology and test,by which the effect of tectonic evolution on hydrocarbon accumulation was evaluated.The result shows that buried hills in Yihezhuang area evolved as following:compressional uplift in Indo-China movement,compression in phase Ⅰ of the Yanshanian movement,extensional subsidence in phase Ⅱ of the Yanshanian movement,compressional uplift in phase Ⅲ of the Yanshanian movement,and again extensional subsidence in Himalayan movement.Fault Yigu991 is a typical contemporaneous fault of inner buried hills in the researching area,and its fault activity rate verifies the tectonic evolution process of the buried hills.The fault of inner buried hills experienced multiple thrust and negative inversion stages under the influence of tectonic evolution that was characterized by many different stress properties.Multi-period tectonic evolution process of inner buried hills is beneficial to the formation of favorable reservoir and effective petroleum migration pathways,and multi-period tectonic evolution,which is well-matched with interior barriers,is beneficial to the formation of favorable reservoir-cap combinations and multiple trap types.The researching result guides oil and gas exploration of inner buried hills in researching area powerfully.With the guidance of tectonic evolution analysis,effective petroleum migration pathways prediction and favorable traps were described,the inner buried hill reservoir such as Yigu72 and Yigu65 were found successfully.关键词
