用模拟实验和多元汽液平衡模拟计算结果,分析了样品的地球化学性质、生烃过程以及实验温度对实验排油效率的影响.认识到生油是排油的主要动力,热蒸发是热压排烃模拟实验视排油效率失真的主要因素.在此基础上,给出了定量评价实验排油效率可信度指标和合理的视排油效率算法.

Based on the simulating experiments and calculated results of multivariant gas-liquid balance sitnulation,the geochemical characters and hydrocarbon-generating processcs of samples and the influnce of experimental temperature on oil-expelling efficiency were analysed.The authors recognized that oil generation was a main motive force for oil-expelling;thermal evaporation was a major factor resulting in a false apparent oil-expelling efficiency in the thermal pressure oil-expelling experiment.On this hasis,a confidence index for quantitative evaluation of experimental oil-expelling efficiency and a reasonable calculating method of apparent oil-expelling efficiency were suggested.
