用热模拟图版校正法计算高成熟烃源岩油气资源量——以南华北盆地济源凹陷为例

Using the Emendation Method of Thermal-simulation Experimental Plate to Calculate Oil and Gas Resource for Highly Mature Source Rock——Example as Jiyuan depression is Southern-Huabei Basin

以济源凹陷为例对高成熟烃源岩油气资源量计算方法进行了探讨 ,对热模拟实验的原理与干酪根演化的地质过程进行比较分析。提出实际应用热模拟产烃率图版及镜质体反射率 (R0 )—排烃效率法计算高成熟烃源岩资源量时 ,应考虑液态烃“死亡线”及地质体中烃源岩热演化过程的开放性、阶段性和排烃效率 ,并分析构造运动对油气资源的破坏等因素对热模拟实验产烃率图版进行校正 ,利用校正后产烃率图版计算油气资源量能较客观地反映成熟烃源岩盆地的油气资源潜力。

In this paper, the method to calculate the oil and gas resource for highly meture source rock in Jiyuan deperession is discussed, and the principle of the thermal-simulation experiment and the geological process of kerogen evolution are compared and analyzed. This paper also concludes that the floor of the liquid window and opening character, phases and the hydrocarbon expel rate of the source rocks in geological process should be considered when the thermal-simulation hydrocarbon producing rate plate and R...
