Through special processing of the dipme-ter log date combined with core observation and conventional log data, the authorsverified the model of dipmeter interpretation, determined successfully the beddingtypes of sandbody and the direction of paleocurrents and indicated the direction ofsandbody extension and thickening as well as the features of deposition and distri-bution of four sedimentary microfacies in the Shasanzhong Submember of Machang.

通过地层倾角资料进行特殊处理，结合岩心观察、常规测井资料，验证了倾角解释模式，成功地确定了砂体的沉积层理类型、古水流方向，指出了砂体延伸和增厚方向，阐明了下第三系沙河街组沙三中亚段四种沉积微相的沉积和分布特征。

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。

In this paper, the upper member of Eh〓, Shuanghe ～ Zhaoao area, Biyang basin, is treated as a case to study outer and iuner configuration of terrigenous sequence, based on the synthetical analysis of seismic, core, welllog and geological data. Using computer simulation technique of quantitative sequence stratigraphy, accommodation diagram, and baselevel analysis theory, the controling factors. formation, and procedure-responsed mechanics of terrigenous sequence are discussed.

文中以双河～赵凹地区下第三系核三〓段为例，综合利用地震、钻井、测井、地质等资料，剖析了泌阳断陷陆相层序外部构型和内部构型；采用定量层序地层学计算机模拟技术、可容空间图解方法及沉积基准面分析原理，探讨了泌阳断陷陆相层序控制因素、形成机理及其过程—响应机制。

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.

通过以上的研究，形成了一套对火山岩储层特征及有利火山岩储层分布模式研究的理论与方法，这种方法不仅适合南凹陷下第三系火山岩储层的研究，而且对其它地质条件相似区域的火山岩特征研究也有很好的参考价值。

The formation of the stripping and gliding nappes is due to the regional structural setting, the sediments of Paleogene system, the soft roof and the uneven rising movement of structure units.
