摘要:
针对南华北盆地上古生界油气勘探难题,在油气地质理论的指导下,进行大量踏勘和岩心观察,利用实验室烃源岩有机显微组分鉴定、残余TOC测定、热解分析和镜质组反射率测定等方法,对豫西地区C—P烃源岩进行了有机地球化学特征分析,以期解决豫西地区煤系地层厚度大但尚无油气藏发现的问题。研究发现:烃源岩类型包括炭质泥岩、生物碎屑灰岩、煤岩和暗色泥岩等烃源岩,分别受控于该区的沉积环境演化,地层从下向上表现为1个规模较大的海进—海退旋回,太原组沉积中期为最大海侵时期,对应的烃源岩应为原始条件下最好的烃源岩|烃源岩有机质类型主要以Ⅲ型干酪根为主,生烃潜量极低,远低于良好烃源岩标准,依据残余有机指标评价为差烃源岩或非烃源岩|烃源岩生烃潜量低且倒挂的现象主要由过高热演化程度、大量断裂发育以及不同岩性的CH4吸附能力差异导致。对于整个豫西地区油气勘探而言,保存条件极好或者受区域热事件影响较低的地区可能为潜在的有利区。
