| 英文摘要 | Based on an analysis of the present geo-temperature field and the thermal conductivity (k) of 62 samples from the central-south area of the huaibei coalfield in eastern china, we calculated the heat flow and plotted its distribution map. the results show that the average heat flow in the research area is about 60 mw/m(2). it is different from other major energy basins in the north china plate, but has close relationship with the regional geology and the deep geological setting. the heat flow is comparatively higher in the southeastern, central, and northwestern areas than in the northeastern and southwestern areas. the geo-temperature distribution map of the bottom interface of the permian coal measure was drawn by calculating its embedding depth and geo-temperature gradients. finally, the present gas generation condition of the permian coal measure is discussed by associating with the temperature condition, the vitrinite reflectance (r (o)), the metamorphism of coal and tectonic-burial evolution. the study indicates all present characters of the permian coal measure, such as lower present temperature, higher r (o) value, middle-high rank coals, and uplift and extension events after the coal measure sediment, are favorable for the generation of secondary biogenic gas, but not thermogenic gas or primary biogenic gas. |
