The Analysis and Analogy Evaluation of the Forming Conditions in Typical Coal-bearing Basins of Outer Daqing

摘要

Jixi Basin, Hegang Basin and Boli basin are major coal mining areas of the Daqing Exploration Area. They are rich in coal resources. In this paper, through analyzing the main controlling factors of the enrichment and reservoiring of the CBM, and the analogy of geological conditions between basins in studying area and other basins, the coalbed methane exploration and development is very successful. Basing on this, the article chooses Fuxin basin and Black Warrior basin as contrast basins to predict the resource by analogy, as the two basins have the similar geological conditions with the basins in studying area. The results show that Jixi basin has the highest total CBM resource, which is as much as 1672.07×10~8 m~3. And Hegang basin has the highest score of the potential enrichment of resource, so these two are preferred profitable exploration basins.
