摘　　要：准噶尔盆地南缘芦草沟组油页岩主要发育于博格达山北麓,位于准噶尔盆地和博格达山构造转换带.研究区内芦草沟组油页岩含油率和厚度分布差异性较大,有机质类型以腐泥-腐殖腐泥型为主,整体上可采性较好.大型开阔湖盆沉积环境有机质产量大,缺氧还原性水体环境是研究区油页岩矿主要控矿因素.博格达山隆升及大型逆冲推覆带和强烈褶皱有效抑制了油页岩有机质热演化进程,是本区油页岩成矿重要条件.综合油页岩矿地质特征及成矿控制因素,认为在叠合盆地内,原陆内坳陷基础上发育的局部构造隆升带是油页岩发育有利前景区.The Lucaogou formation oil shale mainly located in north piedmont of Bogeda mountain,where is a tectonic transfer zone. Research result show that the oil content and formation thick of the Lucaogou oil shale is different clearly through the study area, and the types of organic are sapropelic and humosapropelic, implying a better organic quality. The overall recoverable situation of oil shale is good. The main developmental control factor of oil shale is the stratum sedimentary environment, which is belong to Large open lake basin, with enormous organic matter production and favorable reduction water environment. And the uplift of the Bogeda mountain and concomitant large scale thrust fold belt had effectively limited the organic thermal evolution, which is the structural condition for oil shale formation. According to the geological features and the main mineralization factors, it could be concluded that the Local tectonic uplift belt evolved from Intra-continental depression in the superimposed basin is the prospective area ofoil shale formation and exploration.
