【摘要】 柯克亚周缘地区具有与柯克亚相似的优越油气源条件和成藏条件,构造解释成为其勘探成功与否的关键.本文通过对柯克亚及其周缘地区地震,非地震,钻井,野外露头的综合分析,依据现代冲断带构造理论分析了三条分别切过柯西,柯克亚和柯东的南北向剖面,研究了不同构造段的几何学和运动学特征,并进行了细致的比较.认为它们构造特征的差异主要体现在反冲构造,冲起构造的发育和逆冲推覆的规模上.造成差异的主要原因在于其盆山边界动力条件不同,基底差异和早期构造的影响等.更多还原

【Abstract】 The study on the hydrocarbon source and petroleum accumulation in the adjacent area of Kekeya shows that there is very good petroleum geological condition in these areas as that in the Kekeya area.Now whether we can give a correct tectonic interpretation has been the key to succeed in our exploration.According to the modern theory of thrust belt tectonics together with the seismic,non-seismic,drilling,and field outcrop data of the adjacent area of Kekeya,we select three N-S sections across the Kexi(west of Kekeya),Kekeya and Kedong(east of Kekeya),respectively,to analyze the geometrical and kinematical features of structural segments and to identify the distinction among them in detail.It can be concluded that the main difference of their tectonic features was characterized by the development of the reverse thrusting and pop-up structure,and the size of thrust nappe.The main cause for the difference is the different border condition between the mountain and the basin,and the basement and the effect of earlier tectonism.更多还原
