Abstract: Based on the field geological survey and the previous research achievements, oil shale characteristics in Kazuo basin are presented, the resources type and distribution are found out, the exploration targets selection is optimized, and then the exploration deployment suggestions are put forward. In Member No.1, No.2 and No.3 of Jiufotang formation in this basin developed first, second and third oil shale groups respectively, among which Group 3-1 oil shale appears in many outcrops, with big thickness and high control degree. The type of oil shale is mainly grey-black, brown-black mudstone, most belong to medium-low grade refractory high ash oil shale. The type of resource is predicted resource and the data show that Group 3-1 is of the greatest industrial or commercial significance, which mainly occurs in Meileyingzi sag. Based on the results of selection of oil shale exploration targets, it is suggested that Kazuo basin can be divided into all-round systematic exploration area, extensive network exploration engineering operation area and special geological survey area in terms of exploration deployment.

Key words: Kazuo basin, oil shale characteristic, oil shale resource, target selection, exploration deployment
