Study on occurrence features as well as exploration and development of coalbed methane in Shouyang North Block Shanxi

In order to eveluate the development potential of coalbed methane resources in the North Block of Shouyang,with the collection on the previous coalbed me thane exploration achievements and the coalbed methane parameter well information,Shanxi,an analysis was conducted on the geological condition,seam development,gas bearing,coal reservoir features and other aspects. The analysis held that the block would have the enrichment occurrence conditions of coalbed methane. No. 3 seam of Sh anxi Formation,No. 9 and No.15 seams of Taiyuan Formation would be target seams in the block and No.15 seam would be the main seam.The structure in the northeast p art of the block would be simple, the main seam was well developed with the moderate buried depth,the high seam thickness,the high gas bearing,the low permeability and t he good sealing and would be the favorable block for the next exploration and development of coalbed methane.
