通过对突泉盆地内ZK-WJT井红旗组(Jh)和ZK-13井万宝组(Jw)烃源岩的发育特征和有机质丰度、类型及成熟度的研究对比表明:Jh和Jw烃源岩较为发育,2套生烃层系中有机质丰度较高,均具备一定的生烃潜力;烃源岩有机质类型均属于Ⅱ、Ⅲ型,其中Jh烃源岩有机质类型以Ⅱ型为主;烃源岩有机质演化程度较高,均处于成熟-高成熟演化阶段。综合评价认为,突泉盆地Jh和Jw均具备一定的生烃潜力,相较而言,Jh生烃潜力优于Jw。
The comparison of the development characteristics, organic matter abundance, types and maturity of the ZK-WJT well Honghe Formation (Jh) and the Zk-13 Jw source rock in the Shuquan Basin shows that the Jh and Jw sources The rocks are relatively developed, and the organic matter abundance in both sets of hydrocarbon-generating strata is relatively high, both of which have certain potential for hydrocarbon generation. The organic matter types of source rocks belong to type II and type III, of which the type of organic matter is mainly type II in Jh source rocks. The organic matter of source rocks has a high degree of evolution, both in mature-high-maturity evolution stage. According to the comprehensive evaluation, both Jh and Jw in the Shuquan Spring Basin have some potential for hydrocarbon generation. In contrast, the hydrocarbon potential of Jh is better than that of Jw.
