| Abstract: | According to large amounts of drilling, seismic and geochemical data of deep layers in Jiyang depression, the existent situation and geocheforcal behaviour of the two sets of coal measure strata of Permo-Carboniferous and Mesozoic were studied, and the timing, the threshold depth and the threshold maturity of the "secondary generation of natural gas" were also discussed. The quantity of the secondary generated gas and the accumulation volume of coal-type gas were calculated, and the exploration prospective of coal-type gas was pointed out in this paper. |
