摘要

利用未混油或混油源岩样品

通过控制含油量、温度、压力、时间和含水量等实验条件

系统进行了煤在各种条件下的排油效率及机理实验

并与相近条件下的湖相泥岩进行了对比。结果表明

煤成油可以排出其母源

排油系数约为5%～25%

但在同等条件下

明显低于湖相泥岩约10%.

Abstract

Simulation experiments of primary or oil-added source rocks(some oil was added into source rock)have been conducted.The oil expulsion efficiency and mechanism of coal at different oil saturations

temperatures

pressures

time and water saturations have been systematically studied and compared in detail with those of mudstone.The results indicate that coal-formed oil could expel its mother souree

and its expulsion efficiencies are about 5%～25%

which is 10% lower than those of mudstone at the same conditions.
