In order to identify the disputed oil source in Suaiqo-Wen'an region, Baxian sag, Jizhong depression, on the basis of source rock evaluation and oil-to-source correlation in this region, we recognized the typical Palaeogene oil and Carboniferous-Permian oil viz. two-ends oil, and established effective identification index from detailed analysis of biological marker, separation of nitrogen containing compound, stable carbon isotope and also make reference to the foreign studies on coal derived oil.

针对长期以来冀中坳陷坝县凹陷苏桥-文安地区存在的原油来源争议的问题，在对本区烃源层评价认识和油源对比的基础上，运用生物标志物精细检定、含氮化合物的分离检定、稳定碳同位素分析等技术手段，并结合国内外煤成油的研究成果，划分出了坝县凹陷典型的下第三系原油和石炭-二叠系原油，即两类端元油，并提出了有效的判识指标。

博兴洼陷下第三系岩性油藏的形成具有&复式排烃、排聚耦合和四元控藏&的总体特征，而其独特的烃源岩结构和地层压力系统决定了沙四上亚段和沙三段烃源岩在排烃方式、排烃机制以及岩性油藏成藏特点上的不同。

During the preresearch on the testing well location selection in the south of western depression, three kinds of process and research work have been done according to the log datum on Well Moushen:(1)Formation analysis and formation pressure evaluation which verdicts that formation under 5198.5m is not of Trias, whereas is still in Permian, and abnormal formation pressure phenomenon exists in Members 1 and 3-4 of Shahejie Formation;(2)Re-interpretation of oil and gas formation and evaluation of reserve formation;(3)Evaluation of oil source rock. Members 1 and 3-4 source rocks of Shahejie Formation have good capability of oil generation.

在东濮凹陷西洼南部探井选位的前期研究中，根据该井的测井资料情况，做了三方面处理和研究工作：①地层分析和地层压力评价，认为5198.5m以下的地层不是三叠系而仍是下第三系，沙一段和沙三段—沙四段存在高压异常；②重新解释油气层和评价储集层，在沙三段—沙四段发现6层12.87m厚可疑油层；③评价油源岩，认为沙一段和沙三段—沙四段油源岩具有较好的生油能力。

Multiple-set oil-generation series of strata being of different geologic-geochemical characteristics were formed because of the staging property of the filling and evolution of Lower Tertiary lake basin and the cyclicity of sedimentary proce...

下第三系湖盆充填演化的阶段性和沉积过程的旋回性，形成了多套具有各自地质地球化学特征的生油层系。

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.

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。

Through the study above, it formates a set of theory and method on the favourable reservoir characteristics and distribution modle of volcanic reservoir.The method can not only be applied into the volcanic rock reservoir studies of the Nanpu Sag Lower Tertiary, but also can private a good reference value to reserch on the other volcanic rocks which have the similar geological conditions.
