石油生成需要适当的温度条件,根据地热演化历史可以计算TTI值并定量估计成油窗口的位置。从而确定石油钻探需要达到的最大深度。本文根据盆地沉积史的地质资料和沉积物水文、热学和力学性质的实验室分析资料。对变形—孔隙水—热传输的非线性耦合问题进行了有限单元法计算。在不同而复杂的地质—热演化条件下,对地温、孔隙水压力和TTI值作出了全面估算。更加精确地确定了成油窗口的位置。 The generation of oil requires proper temperature conditions, TTI values ​​can be calculated from the geothermal evolution history and the position of the oil window can be quantitatively estimated. Thus determining the maximum depth that an oil drilling needs to reach. Based on the laboratory data of geological data and hydrological, thermal and mechanical properties of sediments in the basin, The finite element method is used to calculate the nonlinear coupling problem of deformation-pore water-heat transfer. Under different and complicated geological-thermal evolution conditions, a comprehensive estimation of the geotemperature, pore water pressure and TTI values ​​has been made. More precisely determine the location of the oil into the window.
