在普查勘探工作中采集到的石油,其化学成分可为区域勘探阶段中一些地区含油气远景评价的地球化学标准。在这种情况下,石油显示的本身并不是解决地区远景问题的明确标志。只有全面的地球化学分析才能判断,是象世界大多数油田那样的“正常石油”
The petroleum collected during the census and exploration work can have the chemical composition of geochemical criteria for the evaluation of the hydrocarbon-oil future in some areas of the exploration stage. Under such circumstances, the oil shows themselves are not a clear sign of solving the long-term problems of the region. Only a comprehensive geochemical analysis can tell if it is “normal oil” like most oil fields in the world
