| 摘 要： | 通过对细粒天然磁铁矿的穆斯堡尔谱研究和对华北冀东油田第三系砂岩样品的磁性载体成分、成因、剩磁稳定性和特征剩磁方向的研究，探讨了烃类的化学吸附作用与岩石剩磁稳定性之间的关系，烃类的化学吸附作用能够降低岩石的剩磁稳定性，因此，可能会导致产生次生剩磁。这一认识为客观全面地了解各种次生剩磁的成因、研究重磁化现象的时空分布规律，进而为探索新的磁清洗方法和应用岩石磁学方法研究含油气地层的地质问题提供了新的思路

| Abstract: | By means of Mossbour spectrum studies of natural magnetite grains, associated with other methods as electrical probe, X ray diffraction, alternating demagnetization and remanence studies of sandstone from Jidong oil field, Hebei province, the authors of this paper investigated the relations between hydrocarbon chemical adsorbtions and magnetic remanence stabilities. It is recognized that hydrocarbon chemical adsorbtions could decrease the remanent stabilities. The prelimitary results provide a foundation for understanding various causes of remagnetization, searching for new demagnetization methods and applying rock magnetism to study geological problems in oil bearing stratigraphy. |
