【摘要】 近年公布的中国第一大气田苏里格,以及山西的沁水气田的产气层均为石炭-二叠系,在石炭-二叠系沉积时整个华北克拉通大体可分为北、中、南三个带,烃源条件具有广泛性。在印支运动、燕山运动和喜马拉雅运动中,华北克拉通分割成六个“地块”,各地运聚条件差别很大。在构造简单且有三叠系覆于石炭-二叠系之上时,对气田(藏)保护有利。在鄂尔多斯和沁水应扩大勘探成果,在渤海湾应深入研究二次生烃和再次运移,在南华北盆地、汾河地堑盆地和巴音浩特等盆地应突破找气关。更多还原

【Abstract】 The first giant gas field-Sulig gas field and Qinshui gas field in Shan xi province come out with in China in resent years,their gas producing zones Carboniferous-Permian when deposited could be divided into the northern,centra l and southern belts like craton block of North China platform,and have broad s ource conditions.During Indosinian,Yanshan and Himalayan movements,the North China’s craton was separated into six blocks,forming very different conditions of hydrocarbon migration and accumulation.Where the structures were simple and Triassic covers Carboniferous-Permian,gas fields or pools were favorably prot ected.It is concluded that in Erdos and Qinshui areas should perform further e xploration;in Bohai Bay basin should pay attention to in-depth study of second ary hydrocarbon generation and migration;in South Huabei basin,Fenghe graben b asin and Bayinhaote basin should breakthrough the pass for gas prospecting.更多还原
