2、圍,成為油氣勘探的“黃金帶”,但勘探實(shí)踐證實(shí)中國疊合盆地發(fā)育多個(gè)勘探“黃金帶”。多勘探“黃金帶”的形成有3方面因素:①烴源灶多期、多階段發(fā)育與古老烴源巖“雙峰式”生烴;②儲集層多階段發(fā)育;③成藏多期性與晚期有效性常規(guī)烴源灶、液態(tài)烴裂解氣源灶以及多套規(guī)模有效儲集層控制了“黃金帶”的時(shí)空分布;勘探“黃金帶”具有繼承疊置與橫向遷延的特點(diǎn),其中古隆起、古斜坡、古臺緣與多期繼承性斷裂帶控制了勘探“黃金帶”內(nèi)油氣分布。多勘探“黃金帶”的提出是對中國近年來油氣發(fā)現(xiàn)規(guī)律認(rèn)識的深化,表明中國疊合盆地深層仍有經(jīng)濟(jì)資源,油
