Abstract: The Suqiao buried hill hydrocarbon is a representative's example of both primary reservoir in Paleozoic and breakthrough of exploration history in coal-formed oil/gas fields at North China plateform in early 80 years.It was the focus reservoir made more attention by our domestic petroleum geologists at that time. Based on the study of geological structures and potential reservoir conditions of Wenan slope &Baxian depression,author concludes that hydrocarbons of Suqiao reservoirs were mainly generated by lacustrine claystone of Tertiary in Baxian depression,perhaps only few hydrocarbon generated by coal beds.This paper also analyzed some public papers in which conclusions were the Suqiao reservoir generated from coal beds according to both the geochemistry and so called evidents of coal formed hydrocarbon studies.Finally,the paper said so far there are no real strong evidents support to the coal formed gas and for some key items there are no satisfactorily explanation.

摘要: 80年代初,苏桥潜山油气藏作为我国煤成(油)气勘探取得重大突破和在华北地台首次发现古生界原生油气藏的典型实例,在国内引起很大反响。笔者从霸县凹陷和文安斜坡地质结构入手,对该区成藏条件逐一进行了分析,得出该潜山带已探明的天然气和石油,主要是由霸县凹陷高成熟的下第三系湖相泥岩生成的,也可能混有少量C—P煤系烃源的结论。并对C—P煤系地层的成藏条件及煤成烃地质和地球化学证据进行了讨论,认为它尚未对一些关键问题作出令人信服的解释。
