Abstract:
Kaping-Jianhe region situated in the boundaries of Tangshan City is a basin superposed by Paleozoic,Mesozoic and Cenozoic sediments.The basin contains 20 coalbeds and 9 recoverable coalbeds,the cumulative thickness increases from southeast to northwest.The coalbeds contain rich organic carbon,microfabric is mainly vitrinite,the coals are gas coal and fat coal of moderate evolution with strong gas generatim ability.The buried depth of Kaping syncline increased from southeast to northwest,so as the amount of coalbed gas,the metamorphic grades and the amount of absorbed hydrocarbon.It suggests that the northwest part of the basin possesses favourable gas exploration prospects,and that the target beds are those buried deeper than 800 m.
Key words: coalbed gas, gas-bearing potential, absorptivity, effective thickness, Kaping-Jianhe region
