摘要
我国北宋时期的大科学家沈括,是提出油气运移概念的第一人。随着科学技术的发展,油气运移的研究也不断深入。首先,是荧光薄片技术的应用,它使石油初次运移状态能够被人们所观察。其次,是自生矿物烃类包裹体技术的应用,对于油气二次运移中烃类相态的判断,更加明确和可靠。再次,是用有机地化指标对比油-油和油-岩技术,可以宏观地判断油气运移的方向。再次运移在国内外许多含油气盆地无疑是存在的,如准噶尔盆地克拉玛依油田侏罗系油藏,四川盆地川东石炭系和川南二叠系气藏,在国外如扎格罗斯盆地新生界油藏都得到了科学的阐释。
The first person who proposed the concept of petroleum migration is Chinese great scientist Shen Kuo in North Song Dynasty. With the development of science and technology, the study on petroleum migration has been developing unceasingly. Firstly, the fluorescent thin-section technology is in application, which allows primary petroleum migration state to be observed by people. Secondly, the authigenic mineral hydrocarbon inclusion technology is in application, which makes hydrocarbon phase state during secondary petroleum migration have been figured out and more and more clear and reliable. Thirdly, the oil-oil and oil-rock organic geochemical index correlation technology is in application for macroscopic prediction of direction of oil-gas migration. The re-migration of petroleum is beyond doubt in petroliferous basins at home and abroad, for instance, Jurassic oil reservoir of Karamay oilfield in Junggar basin, Chuandong （eastern Sichuan） Carboniferous and Chuannan （southern Sichuan） Permian gas pools in Sichuan basin; foreign Cenozoic oil reservoir in Zagluos basin, all of which have been explained scientifically. Based on such three-division petroleum migration, this paper presents more complete definition about the petroleum migration process.
