| 摘 要： | 统计分析了我国14个主要含油气盆地或地区的主要油气化探指标强度及变异特征,提出了我国主要含油气盆地区域地球化学场划分准则。对我国主要含油气盆地区域地球化学场的变化规律进行了研究,指出了自西向东地球化学背景场渐渐降低,即区域地球化学背景场的分布和变化特征是:西部盆地为高区域背景场,中、东部和近海盆地为中等区域背景场,东北部盆地为低区域背景场的分布特征。变异性则不断增高,即自西至东由均匀场向非均匀场变化的规律。烃类湿度系数具有西干东湿的变化趋势。讨论了六盘山等盆地的分区场特征。 |
| 关 键 词： | 中国含油气盆地 区域地球化学场划分准则 分区场 |

| Abstract: | Based on a statistical analysis of the main oil-gas geochemical indices and variation characteristics of 14 major oil-and gas-bearing basins or areas in China, this paper puts forward the criteria for classifying regional geochemical fields of the major oil-and gas-bearing basins. The variation regularity governing regional geochemical background fields of the major oil-and gas-bearing basins in China has been studied. It is pointed out that from west to east the geochemical background fields tend to decrease in intensity. The distribution and variation regularity of the regional geochemical background fields is as follows: The basins in western China are of the high regional background field, the basins in central and eastern China as well as the offshore basins belong to the intermediate regional background field, and the basins in northwestern China are of the low regional background field. Their variation also tends to increase i.e., from west to east, the fields change from uniform fields to nonuniform fields. The moisture coefficients of hydrocarbons tend to change from dry in the west to wet in the east. The zonal field characteristics of such basins as Liupanshan are discussed. |
