| 摘 要： | 针对柴达木盆地侏罗系油气勘探目标选择的难点,从烃源岩与圈闭时空配置的角度,建立侏罗系油气早期聚集早期成藏、早期聚集晚期成藏、晚期聚集晚期成藏3种模式。盆地油气来源、充注时期、油藏调整及破坏等方面存在规律性,这决定了油气分布的有序性,呈现出“断褶区聚气,山前、潜伏区聚油,凸起顶、凸起斜坡区油气并存”的基本格局和油气富集程度依次变好的序列。据此预测油气富集范围,从中优选冷湖4号东斜坡、乌南—巴依凸起斜坡、怀头他拉—德北斜坡、潜伏Ⅰ号等新靶区。

| Abstract: | It is very difficult to decide the most vantage points for drilling Jurassic petroleum in Qiadam Basin. From theviewpoint of collocating the source and traps in space and time, this paper sets up three modes of pool formation, thatis,early accumulation-early hydocarbon reservoir formation, early accumulation-late hydocarbon reservoir formation, andlate accumulation-late hydocarbon reservoir formation.The characteristics of oil and gas origin, infusing time, and refor-ming or destroying determine the arrangement of oil and gas reservoirs in a particular order. The order may be describedas follows: natural gas accumulates in the faultage-anticline zone,oil congregates in piedmont and latency,oil and gas co-exist in the top and slopes of uplift. Furthermore, the grade of the enrichment in this order gradually increases. Accord-ing to the regularity, the enrichment corners can be predicted, among which the eastern slope of Lenghu-4, the slope ofWunan-Bayi uplift, the slope of Huaitoutala-North Delingha and Latency-1 are the unexceptionable drilling targets. |
