摘　　要：利用GP0 2 A高频感应加热设备产生高频磁场 ,等离子体在高频磁场中激活氧气形成活性氧 ,活性氧在低温低压下氧化烃源岩中的有机质 ,从而达到去除有机质并确定其含量的目的。采用射频低温氧化法对我国 7个盆地未熟烃源岩进行了有机质去除的实验 ,结果表明 ,在最佳条件下用 2 0～ 4 0h可把未熟烃源岩中的有机质去除 ,我国 7个盆地未熟烃源岩中有机质的质量含量为 1.5 3%～ 3.17%。The high frequency electromagnetic induction heating equipment GP02-A was utilized to emerge a high frequency magnetic field. Oxygen was activated and became active oxygen by plasma in the high frequency magnetic field. Then active oxygen was oxidized with organic matters in immature source rocks at low temperature, and the organic matters in the immature source rocks could be removed. At the same time, the contents of organic matters could be detected with this method. Experiments for removing organic matters from immature source rocks of seven basins were made by means of emission frequency oxidation at low temperature. The results show that removing of organic matters from immature source rocks needs 20 to 40 hours under the optimum conditions. The measured mass contents of organic matters in immature source rocks of seven basins are in the range of 1.53 percent to 3.17 percent.
