【摘要】：內(nèi)蒙古東部地區(qū)是油氣深部勘探的重點地區(qū)。為評價深部源巖層中上二疊統(tǒng)的油氣資源前景,在野外地質(zhì)勘查、典型剖面實測和樣品分析測試的基礎(chǔ)上,通過有機質(zhì)豐度、類型、成熟度等地化指標(biāo),有機巖石學(xué)方法,生物標(biāo)志化合物以及生烴熱模擬實驗,對中二疊統(tǒng)哲斯組和上二疊統(tǒng)林西組暗色泥質(zhì)烴源巖的分布、地化特征和生烴潛力進行研究。研究表明:哲斯組為淺�！肷詈Ｏ�,林西組為近海湖盆—殘余海相,兩套地層均廣泛發(fā)育巨厚層暗色泥巖;有機質(zhì)豐度以中等—好烴源巖為主,類型主要為Ⅱ2—Ⅲ型,處于過成熟演化階段,有機質(zhì)以陸源高等植物和水生藻類等混源為主,沉積水體為具有一定鹽度的強還原—還原環(huán)境;哲斯組和林西組具有一定的生氣能力,最大生烴量分別達0.62 m3/t和2.48 m3/t。哲斯組和林西組作為潛在的氣源巖,具有良好的天然氣勘探前景。
[Abstract]:The eastern part of Inner Mongolia is a key area for deep exploration of oil and gas. In order to evaluate the prospects of oil and gas resources in the middle and upper Permian strata of deep source rock, the abundance of organic matter is obtained through the field geological exploration, the measurement of typical sections and the analysis and test of samples. Types, maturity and other geochemical indicators, organic petrology methods, biomarkers and thermal simulation experiments of hydrocarbon generation, distribution of dark muddy source rocks in the middle Permian and the Upper Permian Linxi formation, The geochemical characteristics and hydrocarbon generation potential are studied. The results show that the Zesi formation is shallow to semi-deep sea facies and the Linxi formation is offshore lake basin residual marine facies. The abundance of organic matter is mainly intermediate-good source rock, the type is mainly type 鈪，
