【摘要】 乌兰盖盆地属于松辽外围中新生代火山岩覆盖区,利用重力、磁力和大地电磁测深等非地震物探方法调查潜在沉积盆地分布和构造格架,为油气资源潜力评价提供依据。在充分研究盆地岩石地层物性特征的基础上,根据重、磁、电各方法的优势,采用互约束反演技术,开展综合研究,解释推断了盆地白垩系巴彦花群、侏罗系地层的分布形态及构造格架,指出乌兰盖断陷盆地具有很好的找油气前景。更多还原

【Abstract】 Ulgoin basin belongs to the Middle Cenozoic volcanic rock area outside of the Songliao basin.For the purpose of investigating the potential distribution of the sedimentary basin and tectonic framework,the utilization of such means as gravity,magnetic survey,magnetotelluric sounding and other non-seismic geophysical methods is helpful.These methods provide the basis for evaluation of the oil and gas resource potential.Based on an analysis of the physical characteristics of rock strata and taking advantage of the gravity,magnetic survey and electrical method,the authors carried out comprehensive interpretation and determined the distribution and tectonic framework of Cretaceous Bayanhua Group and Jurassic morphology.It is pointed out that the Ulgoin rift basin has a good prospect in the prospecting for oil and gas resources.更多还原
