| 英文摘要 | Bachu uplift is one of the major oil prospect areas in tarim basin. its tectono-thermal evolution significantly influence hydrocarbons formation, migration and accumulation. in this paper, we reveal the burial histories of four seismic profiles spanning bachu uplift and present the tectono-thermal history of this region by solving two-dimensional heat conduction equation. during the simulation, we calculate the average heat flow value at moho surface by using "back tripping" method. then we employ the principle of isostatics to compute the burial depths of moho surface during geological period, finally we calculate the basal and surface heat flow of the basin. the numerical results show that the tectono-thermal history of this region can be divided into seven stages. the maximum of the geothermal gradient and heat flow appeared in triassic period with the value of 32 degrees c/km and 73.6 mw/m(2) respectively, and the minimum of them appears now, the values are 20 degrees c/km and 46.4 mw/m(2) respectively. because of lateral thermal diffusion since the miocene epoch, the average heat flow value of the calculation is slightly greater than actual value. at last, we discuss the influence of thermal conductivity and heat generation on thermal evolution of a basin. |
