博格达山北麓山前弧形冲断褶皱带上发育强烈变形的二叠系油页岩,产出层位为中二叠统芦草沟组。纵向上芦草沟组上段油页岩较下段发育,而品质下段好于上段;横向上以阜康县三工河地区油页岩最发育,含油率高,由此向东、向西两侧油页岩逐渐减薄,品质降低。芦草沟组油页岩形成于高盐度的半深水-深水陆缘近海湖泊环境,属低熟-成熟优质生油岩。油页岩产状以纸状、层状和砂质油页岩3种类型为主,纸状油页岩品质最好。利用体积法估算博格达山北麓芦草沟组油页岩资源为652.39×10~8t,技术可采油页岩资源量226.5×10~8t;页岩油资源量为54×10~8t,技术可采页岩油资源量18.8×10~8t,可回收页岩油资源量14.1×10~8t。三工河地区油页岩品质好,厚度大,埋藏浅,油页岩和页岩油资源量大,是进一步勘查与开发的首选地区。
The Permian oil shale developed strongly on the arcuate thrust fold belt in the northern foot of the Bogda Mountain. The output strata are in the Middle Permian Lucaogou Formation. The upper part of Lucaogou Formation longitudinally developed oil shale, while the lower part of quality was better than the upper part. Laterally, the oil shale in Sankonghe area of Fukang County was the most developed with high oil content, thus eastward and westward Oil shale is gradually thinner, lower quality. The Lucaogou Formation oil shale is formed in a high salinity semi-deepwater-deepwater continental margin lacustrine environment and is a low-maturity-mature high-quality source rock. The oil shale is dominated by three types of paper-like, layered and sandy oil shale, and the paper-like oil shale has the best quality. The volume of Shaluogou Formation oil shale resources in the northern foot of Bogda Mountains is estimated to be 652.39 × 10 ~ 8t by volume method, with 226.5 × 10 ~ 8t shale resources available for technology recovery and 54 × 10 ~ 8t shale oil resources. The available shale oil resources are 18.8 × 10 ~ 8t and the recyclable shale oil resources are 14.1 × 10 ~ 8t. The oil shale in Sangonghe area has good quality, large thickness, shallow burial, large oil shale and shale resources, which is the preferred area for further exploration and development.
