在传统的油气勘探工作中，主要考虑盆地浅部的沉积盖层条件，对深部构造资料利用甚少。对国内外一些含油气区的地壳深部构造特征进行分析，认为沉积盆地含油气丰度取决于地壳总体的结构类型：①凡莫霍面平缓呈斜坡或下凹状的盆地区，油气丰度都很低，而莫霍面隆起区无论盆地基底面呈坳陷状还是隆起状，都可能有油气资源，前者对油气富集更为有利；②花岗质层在结晶地壳中占的厚度比例越少，沉积盖层在地壳总厚度中所占比例越大，对油气富集越有利；③软流圈层隆起高，中、新生代岩浆活动强烈，也有利于油气富集。利用盆地区油气丰度与深部构造的某些相关规律，将浅部与深部的构造研究相结合，可以客观判定盆地中主力油气远景区，以免出现大的勘探决策失误。我国东部、西部地壳结构特征完全不同，油气分布规律亦不同。在西部地区油气勘探中，建议在重点勘探区进行足够量的地壳深部构造区测工作，结合浅部构造条件确定重点钻探目标。此外，根据地幔对地壳作用越强烈的地区油气越丰富，认为很可能油气形成的有机成因论和无机成因论反映了油气形成统一过程中的不同阶段。
In the traditional oil and gas exploration, the conditions of sedimentary cover in the shallow part of the basin are mainly considered, and the data of deep structure are rarely used. Based on the analysis of deep crustal structure in some oil and gas-bearing regions at home and abroad, it is concluded that the abundance of oil and gas in the sedimentary basin depends on the structural type of the crust: (1) Where the Moho is gently sloped or depressed, the hydrocarbon abundance is very high Low, while the Moho uplift may have oil and gas resources regardless of whether the basement of the basin is in a depression or uplift. The former is more favorable for oil and gas enrichment. (2) The smaller the proportion of granite layer in the crystalline crust , The larger the proportion of sedimentary caprock in the total crustal thickness is, the more favorable it is for hydrocarbon enrichment. (3) The asthenosphere uplifts high, and the Mesozoic and Cenozoic magmatic activity is strong, which is also beneficial to oil and gas accumulation. Based on some related laws of hydrocarbon abundance and deep structure in the basin area, combining the study of shallow and deep structures, we can objectively determine the main oil and gas prospect in the basin so as to avoid large exploration decision mistakes. China’s eastern and western crustal structure completely different characteristics of the distribution of oil and gas are also different. In the exploration of oil and gas in the western region, it is suggested that a sufficient amount of deep crustal tectonic area testing be conducted in the key exploration areas and the key drilling targets should be determined in light of the shallow structural conditions. In addition, according to the richer regions where the mantle contributes to the crust, the more oil and gas are considered, it is probable that the organic and inorganic genesis of hydrocarbon formation reflect the different stages in the process of oil and gas formation.
