| 摘 要： | 本文通过对塔里木盆地轮南地区及附近的钻井（出油井和未出油井）中揭示的裂缝，裂缝与成岩序列的穿插关系，连通砂体及断层和不整合面附近的矿物及矿物中流体包裹体研究，对塔里木盆地轮南地区油气运移路径和期次进行了探讨。通过研究指出了塔里木盆地轮南地区主要经历了3期大规模的油气运聚，地层之间的不整合面为油气横向运移的主要通道。高角度的裂隙及微裂缝为纵向运移主要通道。第一期油气运聚主要发生于海西期，第二期油气运聚主要发生在14－17Ma；第3期油气运聚主要发生在最近的5Ma以来。第一期油气运聚主要为自塔北隆起的西南，南向北，以横向运移为主；第二，第三期运聚主要自西南，南向北，自东向西运移，但主要以垂向运移为主。

| Abstract: | This study on the direction, pathway and phase of oil/gas migration in the Lunnan area is based on the crosscutting relation of fissure, fault and rock sequence in the cores of drillhole (successful and unsuccessful) and the analysis of minerals and theirs inclusions near linking sand, fault and unconformity. The result suggests that there were three phases of large-scale oil/gas migration and accumulation, and unconformities served as the main horizontal pathways and high-angle faults and fissures were the main vertical pathways. The first phase occurred mainly in the Hercynian, the second in 14~17 Ma and the third in the last 5 Ma. The first phase of migration, mainly horizontal, were from the southwest and south to the north of the Tabei uplift and the later two phases, mainly vertical, from the southwest and south to the north and from east to west. |
