| 摘 要： | 井中油气地球化学勘探技术研究立足于油气运移的理论,是通过分析钻井岩屑(岩心)中不同赋存状态的烃类化探指标含量,研究不同化探方法指标含量在钻井剖面上的分布特征及变化规律,建立井中油气地球化学剖面,探索研究油气垂向微运移规律,生、储、盖层化探指标变化与组合特征,从而达到判别储层含油气性、评价烃源岩特征、评价盖层特征等石油地质目的,为油气勘探提供地球化学依据。

| Abstract: | The vertical distribution of hydrocarbon geochemical indicators,detected with rock cuttings or cores,depends upon the vertical micro-migration of hydrocarbon and the distribution pattern of the geochemical indicators in the system of source rocks,reservoir rocks and cap rocks,according to the principles of vertical hydrocarbon migration.Borehole geochemical exploration technique aims to detect the concentrations of various phases of hydrocarbon indicators so as to establish a geochemical profile along the borehole.The results could be used as a tool for oil and gas exploration. |

| Keywords: | Borehole geochemical exploration hydrocarbon source rock evaluation reservoir evaluation cap rock evaluation hydrocarbon migration application |
