利用新近钻井资料，对新沟油田的烃源岩发育特征及其原油地球化学特征进行分析，认为新沟地区烃源岩处于未成熟－低成熟演化阶段，具有良好生烃潜力，其原油为低成熟原油和成熟原油。油源对比表明，新沟地区烃源岩与本区原油在成熟度上有较大差别，新二区Ⅲ油组常规油藏来自于靠近洼陷的新392井区新沟嘴组高丰度、成熟烃源岩，而新二区的Ⅰ油组、Ⅱ油组及新一区的油藏均为外来油与本地油的混合。

Through analyzing source rock growth characteristics and its geochemical features of crude oil based on newly drilling data of Xingou Oilfield ,it is determined that in the area the source rock is in evolutionary phase from immaturity to lower maturity with a good hydrocarbon-generation potential and its crude oil is low mature or ma‐ture .Oil source correlation shows that there is a big difference in maturity between its source rock and crude oil . The conventional reservoir of the third oil formation in Xinerqu contains abundant and mature source rocks from Xingouzui formation of Xin 392 wellblock nearby the depression while the reservoirs in the first and second oil forma‐tions of Xinerqu and in Xinyiqu contain the mixture of extraneous oil source and native one .
