摘要
给出了一种利用恒容热解技术反映压力作用的油成气模拟实验方法,采用该方法的实验结果,标定了两个取自塔里木盆地和准噶尔盆地的原油样品的油成气平行一级反应化学动力学模型,该模型可以定量描述热对油藏的破坏程度并预测油藏分布的下限深度.计算结果显示,塔里木盆地油藏受热破坏的起始深度为4 500m,埋深下限大于7 500m,准噶尔盆地油藏受热破坏起始深度为3 250m,埋深下限5 400m～>6500m,与两个盆地油藏分布情况相符.
The paper constructed a simulating experiment technique of gas generation by oil which can reflect pressure action with the fixed volume heating pyrolysis. Based on the technique, the authors calibrated the parallel first-order reactions chemical kinetic models of gas generation by oil of two oil samples from Tarim basin and Zhungeer basin, The degrees of a oil pool thermodestruction can be described and the limit of oil pools depth can be forcasted quantitatively by the models. The calculation indicats that the original depth of oil pools thermodestruction is 4 500m and the limit of oil pools depth is >7 500m in Tarim basin, in Zhungeer basin, the original depth is 3 250m and the limit depth is from 5 400m to >6 500m.
