摘要/Abstract

摘要： 通榆断陷位于松辽盆地西部斜坡区，区域地层发育特征研究认为，松辽盆地西部斜坡区上古生界具有较好的油气勘探前景。但是通榆断陷的上古生界生烃层系地层的发育情况并不清楚。系统采集了松辽盆地西部斜坡区的地层岩石物性标本，测试了密度及电阻率，整理了通榆断陷地区地层岩石物性参数，利用重力和大地电磁测深非地震物探方法，在分析盆地岩石地层物性特征的基础上，根据重力和大地电磁方法的优势，采用互约束反演技术，开展了综合研究，解译推断了断陷内地层的分布形态及构造格架，推断了研究区的构造演化史，为油气资源潜力评价提供了依据。

Abstract: Tongyu fault depression is located in the sestern slope of Songliao basin,based on the study of regional stratigraphic development characteristics,t is believed that the Upper Paleozoic in the western slope of Songliao basin has a good prospect for oil and gas exploration.But the hydrocarbon of stratigraphic strata in the upper Paleozoic is unclear.In this study,stratigraphic physical specimens of the western slope of Songliao basin area are systematically collected and density,magnetization and resistivity are tested.The petrophysical parameters of the strata in Tongyu fault area are systematically analyzed,based on an analysis of the physical characteristics of rock strata and taking advantage of the gravity,magnetic survey and electrical method,the comprehensive interpretation is done and the distribution and tectonic framework of the upper Paleozoic and tectonic framework are discussed.The above study results provide the basis for evaluation of the oil and gas resource potential．

Key words: Tongyu fault depression,Comprehensive interpretation,Upper Paleozoic,Tectonic evolution,Resource evaluation
