| 摘 要： | 本文对黔南拗陷生油岩地化特征进行了分析,认为拗陷生油条件好,生油岩丰富,有机质主要为腐泥型,生烃潜力好。按有机质成熟度大致分为三个区即:低值区、中值区和变质区。并对生油岩热演化史作了论述,对油气演化和构造演化进行了分析。最后,对拗陷进一步的勘探方向提出建议,以供参考。

| Abstract: | On the basis of the analysis of geological characteristics of source rocks in Qiannan depression, the depression is found to have a good hydrocarbon yielding condition. It is rich in source rocks, the organic matter of which is mainly sapropelic type. It has a good potential of hydrocarbon yielding. According to the degree of maturation of organic matter it can be divided into three regions: low maturation region, medium maturation region and over maturation region. The thermal evolution history of s6urce rocks is discussed, and hydrocarbon evolution and structure evolution are analyzed. And finally, some suggestions are made on the direction of exploration. |
