【摘要】 根据三维地震资料的精细解释,系统分析巴喀地区的构造演化及构造样式特征,认为燕山期、喜山期构造运动对巴喀地区构造演化起关键决定作用,主要发育断褶-背斜构造和背冲式构造。针对研究区气藏存在2种不同性质的气源进行研究,认为下侏罗统地层的构造运动控制着该2种气源聚集成藏,从而建立了巴喀地区下侏罗统的油气成藏模式,为该区下一步勘探目标选取提供依据。更多还原

【Abstract】 The tectonic evolution and structural style in Baka area are systematically analyzed based on fine interpretation of 3D seismic data.It is believed that the Yanshan and Himalayan movements had played an important role in Baka tectonic evolution,where mainly developed fault-folded anticlinal structures and back-thrust structures.There are two different types of gas sources in the study area.Lower Jurassic tectonic movement controlled hydrocarbon accumulation from these two gas sources.On this basis,a hydrocarbon accumulation model has been established for the lower Jurassic in Baka area,thus providing knowledge for choosing exploration targets in this area.更多还原
