摘要
对中国松辽、渤海湾、鄂尔多斯、塔里木、准噶尔和吐哈等盆地石油资源丰度的研究表明,不同类型的运聚单元石油资源丰度有很大差异。高丰度运聚单元的石油资源丰度大于30万t/km2,而特低丰度运聚单元的石油资源丰度则小于5万t/km2。潜山型运聚单元、古近纪断陷盆地陡坡构造型运聚单元和古近纪断陷盆地中央构造型运聚单元的石油资源丰度最高,而古生代残留盆地构造型运聚单元的石油资源丰度最低。运聚单元的石油资源丰度主要与有效烃源岩的生油强度、储集层的发育程度、圈闭的发育程度以及上覆地层的区域不整合个数有关。采用回归分析的方法建立了石油资源丰度与上述地质因素的统计关系,这一定量的统计模型可以用于对评价区运聚单元石油资源丰度的预测。
The petroleum resource abundance of different kinds of petroleum plays is very different in Chinese basins. It can be higher than 30 ×104 t/km^2 or lower than 5 × 104 t/km^2. The play with high petroleum resource abundance includes the buried hill, the structural play in steep slopes, and the central structure play in rift basins. The play with low petroleum resource abundance is the play in palaeozoic residual basins. Based on the results of the studies of petroleum plays in 6 basins of China, the relationships between oil resource abundance in place and some geological parameters were studied. It is showed that the oil resource abundance in place was mainly controlled by the generation intensity of source rock, the abundance of reservoirs and traps, and the number of unconformities in overlying strata. The quantitative model is established, which can be used for the prediction of oil resource abundance in different kinds of petroleum plays.
