In different geologic development stage , different geodynamics background and tectonic stress field characteristic led to different baisin types , sedimentary assemblage . basin - mountain coupling forms and produced complex structure deforming . consequently , superimposed basin are characterized by multi - stage basin - formation , multi - stage hydrocarbon generation , multi - stage hydrocarbon accumulation . complex accumulation mode and oil / gas distribution law . tectonic process is key point and decisive in many hydrocarbon accumulation factors of superimposed basin 在不同的地質(zhì)發(fā)展階段,由于不同的地球動力學(xué)背景和構(gòu)造應(yīng)力場特征,導(dǎo)致了不同的盆地類型、沉積組合、邊界條件和盆山耦合形式,產(chǎn)生了復(fù)雜的構(gòu)造變形,從而使疊合盆地具有多期成盆、多期成烴、多期成藏以及復(fù)雜的油氣成藏模式和油氣分布規(guī)律。
