在恢复埋藏史的基础上 ,通过建立成烃演化史模型 ,计算和编制了各时期有机质的成熟度图并分析其成烃演化史。结果表明 ,孙虎地区沙三段有机质从东营组沉积末期开始进入低成熟阶段 ,局部进入成熟阶段 ,目前成熟度仍较低 ;沙四段有机质从沙一段沉积末期开始进入成熟阶段 ,至东营组沉积末期基本成熟 ,局部达高峰阶段 ;孔店组有机质从沙三段沉积末期开始进入成熟阶段 ,至东营组沉积末期全部成熟 ,部分达凝析气阶段。
Based on the restoration of burial history, the maturity map of organic matter in each period was calculated and compiled by analyzing the hydrocarbon evolution history model. The results show that the organic matter in the third member of the Third Member of the Yellow River in the Huaihe area has entered into the low maturity stage from the sedimentary stage of Dongying Formation and enters into the mature stage locally. However, the maturity is still low at present. At the end of the Shahejie Formation, At the end of sedimentation, the sediments are basically mature and reach the peak stage locally. The organic matter of Kongdian Formation enters the mature stage from the sedimentary stage of Shasan Member to the maturity stage, and reaches the mature stage in Dongying Formation at the end of sedimentation and reaches the condensate gas stage at the end.
