| 摘 要： | 从油源、构造背景、油气运移通道、储集空间、圈闭等因素及其配置关系对柴西南地区昆北断阶带基岩油藏成藏条件进行了分析。研究认为,昆北断阶带紧邻切克里克生烃凹陷,为一持续发育的古隆起,多期构造运动形成了以裂缝、溶蚀孔等为主的储集空间,油气运移通道为基底断裂和不整合面。建立了昆北断阶带基岩油藏的2种成藏模式:一种是断层-裂缝输导的纵向成藏模式,另一种为断层纵向输导-不整合面侧向运移的远源成藏模式。

| Abstract: | Based on the study of oil sources,tectonic setting,migration pathway,reservoir space,trap and their assemblage relations,the hydrocarbon accumulation conditions of basement reservoir in Kunbei fault terrace belt in Qaidam basin are analyzed.The study shows that Kunbei fault terrace belt close to the Qiekelike hydrocarbon source sag is a persistent developed palaeohigh.With effects of multi-tectonic movements,the reservoir space is dominated by fractures and dissolution pores,and two models for hydrocarbon accumulation in basement reservoir in Kunbei fault terrace belt are developed: one is vertical migration and accumulation model by fault and facture as channels,the other is remote source lateral migration and accumulation model by fault and unconformity. |
