本文在前人研究的基础上,通过对乌伦古坳陷滴北地区侏罗系露头、岩心、测井、地震等资料分析研究,明确了该地区侏罗系各沉积时期地层的展布范围、沉积相类型及砂体的主要发育时期,有效地指导寻找有利储层,为下一步成藏控制因素的研究奠定了基础。 Based on the previous studies, by analyzing the Jurassic outcrops, cores, logging and earthquakes in the northern part of the Ulungugu Depression, the paper expounds the stratigraphic distribution range of each Jurassic sedimentary period , Types of sedimentary facies and the main developmental stages of sand bodies, effectively guide the search for favorable reservoirs, which lays the foundation for the research on the controlling factors of reservoir formation in the next step.
