The temperature logging curve of Dingshan 1 shows that as the depth goes to higher the temperature rising，the value is 25 ℃ at the top，and 107.5 ℃ at the bottom. The temperature logging curve has an “arch” at the depth of 1 000～3 000 m. According to the characteristic of geothermal gradient section and its relationships and pertinences with the thermal conductivities and lithology of the stratum，the authors reach a conclusion that the vertical motion of subsurface fluid caused the perturbation of the temperature curve. This conclusion is adopted to deduce the strata of Cambrian have high porosity and permeability，while the strata of Silurian-Ordovician have a high sealing capacity，and this assembly of strata is propitious to the hydrocarbon’s accumulation. It may be an indication of that there is a potential of the Lower Assemblage in southeastern Sichuan Basin.
