THE CHARACTERISTICS AND RESOURCE POTENTIAL OF COAL-BEARING FORMATIONS IN UPPER PALEOZOIC IN DAGANG OILFIELD
大港探区上古生界煤系烃源岩特征及资源潜力

Coal-bearing Formations in upper Paleozoic distributes extensively with large thickness, high organic matter abundance and high hydrogen content in maceral. Especially in southern area of Huanghua depression, the source rocks is completely preserved, and being continually subsided, with better condition of secondary hydrocarbon generation, so that it is the advantaged zone for exploring coal-related gas. The resource calculation indicates that natural gas resource volume is 1 994×108 m3 from secondary hydro...
