| Abstract: | Changjiang Sag has huge sedimentary deposit, the maximal thickness is 8800m, dark mudstone of lacustrine deposit predominate Tertiary, having good generating conditions. The abundance of organic matter is mid-high and the types is Ⅲ. Most source rock belong to innacle phase. The main generating hydrocarbon center of Changjing Sag is Daguanyuan deep sag, the area is 6758.75km 2, available source rock is big, covering vast area, the maximal sedimentary thickness of Cenozoic is over 5000m, the amount of generating hydrocarbon is 7.219×10 8t, the amount of oil-gas resource is 1.674×10 8t, many tectonic in there, and it is good prospective area in Changjiang Sag. |
