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、裂隙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。
In this paper, through the interpenetration relationship between fractures and fissures and diagenesis sequences revealed in drilling wells (out of oil well and out of oil well) in and around Lunnan area in Tarim Basin, the fluid inclusions in the connected sand body and in the minerals and minerals near the fault and unconformities In this paper, the hydrocarbon migration path and period of Lunnan area in Tarim Basin are discussed. It is pointed out through the research that the Lunnan area in Tarim Basin experienced three major phases of hydrocarbon migration and accumulation. The unconformity between the strata is the main channel for the lateral migration of oil and gas. High-angle fractures and micro-fractures are the main channels for longitudinal migration. The first phase of hydrocarbon migration and accumulation mainly occurred in the Hercynian period, and the second phase of hydrocarbon migration and accumulation mainly occurred in 14 ~ 17Ma. The third phase of hydrocarbon migration and accumulation mainly occurred in the recent 5Ma. The first phase of hydrocarbon migration and accumulation is mainly from southwest to north to north of the Tarim uplift and mainly to horizontal migration. The second and third phases of migration and accumulation mainly migrate from southwest to south to north and from east to west, Mainly to the vertical migration.
