摘要
经勘探证实冀中坳陷文安斜坡带已有奥陶系潜山、二叠系上石盒子组砂岩段及下第三系三个含油气层位。其烃源岩为石炭—二叠系煤系和下第三系暗色泥岩。本文根据各含油气层中的油气及烃源岩的地质、地球化学特征的对比分析,确认奥陶系及二叠系中的原油来自石炭—二叠煤系烃源岩,属煤型油。下第三系原油来自本身的烃源岩。奥陶系和二叠系中天然气的成因类型为凝析油伴生气,由石炭—二叠系煤系烃源岩提供,属煤型气。
In this paper, according to the contrast and analysis of geological and geo-chemical characteristics of source rock, as well as oil and gas of all oil-bearing horizons, it is believed that the crude oil of the buried hill of Ordovician and Permian systems is due to the same type. The crude oil which comes from the source rock of Carboniferous-Permian coal formation is the coal-type oil its dif-ferent type forms the crude oil of lower Tertiary system which comes from the source rock of itself. The paper has also discussed the genetic types of natural gas from Ordovician and Permian systems and their source. It is confirmed that the accompanying gases of condensate oil coming from the Carboniferous-Permian coal formation are coal-type ones.
