中文摘要：

由于传统的古地温梯度恢复方法均具有局限性,沉积盆地热史定量研究一直是地质学界的难题.根据包裹体内气体压力与其激光拉曼谱的出峰位置存在相关性这一原理,由实测激光拉曼数据确定实验室条件下包裹体压力,结合包裹体均一化温度计算出天然气成藏时的包裹体压力和地温梯度.研究认为：通过地层埋藏史恢复,可确定某一地质时间的古地温梯度;表述热史的最佳指标是古热流,而不是古地温梯度;根据盆地热力学原理,可以由古地温梯度计算得到古热流;松辽盆地的古地温梯度和古热流值均高于现今.

英文摘要：

Due to the limitations of conventional paleo-geothermal gradient buildup methods, it is always hard to quantitatively study the thermal history of the sedimentary basins for the geological field. Based on the correlation principle between the gas pressure in the inclusions and peak locations of its Laser Raman Spectroscopy, the experimental inclusion pressure is determined by the measured laser Raman data, and it was further combined with the inclusion homogenized temperature to calculate the inclusion pressure and geothermal temperature in the gas reservoir accumulation period. The studies show that through the stratigraphic burial history buildup, the paleo-geothermal gradient in the given geological time can be verified; the best index to characterize the thermal history is the palaeoheat flow, instead of the paleo-geothermal gradient; According to the principle of basin thermal dynamics, the paleo-heat flow can be obtained by the calculation of the paleo-thermal gradient; both two paleo-values stated above are all higher than those of the present.
