| 摘 要： | 从地震剖面显示塔里木盆地发育为手风琴式演化史,大体上形成三层"断-坳"结构:(l)震旦系的"断",古生界—三叠系的"坳";(2)侏罗系的"断",白垩系的"坳";(3)古近系的"断",新近系的"坳"。断陷与坳陷分别由拉张与挤压应力场所致,这种应力场的变化是由相邻洋壳板块俯冲倾角由小到大的变化所引起的。由于地壳的多旋回运动,多次发生构造沉积演变,构成了多套生储盖组合,多领域、多种圈闭类型的油气藏,从震旦系—古生界—中生界—新生界,各断陷-坳陷结构的盆地都具有可能形成油气藏的地质条件。

| Abstract: | Seismic Profile shows that the Tarim Basin has experienced a violin -style evolutionary process,which has led to the formation of the three -layer(fault subsidence -depression " structure:(1) Sinian "fault subsidence" and Paleozoic -Triassic "depression";(2) Jurassic "fault subsidence" and Cretaceous "depression";(3) Paleogene "fault subsidence" and Neogene "depression".The fault subsidence and the depression resulted respectively from the pull-apart and the squeezing stress field,and the variation of such ... |
