基于矿物流体包裹体均一化温度、热液矿物分布及其地球化学特征等,识别出了塔中地区重点研究井段埋藏热液溶蚀流体化学性质,探讨其在纵横向的分布及流动特征.研究表明,(1)埋藏热液溶蚀流体在塔中地区较为活跃,并对碳酸盐岩储层有着良好的改造效应,油气勘探前景广阔；(2)北东-南西向走滑断裂发育地带有利于埋藏热液溶蚀流体的注入,研究区TZ45以及TZ82-TZ16井区均是埋藏热液溶蚀流体异常活跃地带.同时,研究还认为,早期表生岩溶作用产生的溶洞体系将被后期埋藏压实作用部分破坏,而其残余空间往往是埋藏热液溶蚀流体进入储层的优势通道,继而发生溶蚀改造扩大溶洞空间.因此,在塔里木深部碳酸盐岩储层的勘探过程中,应充分重视挤压背景下张性断裂的发育及其热流体疏导效应,如走滑断裂强烈活动地带；同时应着重注意多期不同性质流体的叠加改造效应,这些区域可作为优选勘探目标.%Detailed studies of homogenization temperatures of fluid inclusions, distribution and geochemistry characters ofrnhydrothermal minerals provide insights into chemical, distribution and (lowing characteristics of hydrothermal/burial dissolution fluid in Central Tarim. Result shows that the activity of the fluid was prevalent in Ordovician strata, which significantly improved the carbonate reservoirs associated and broaded petroleum exploration prospect In addition, the aforementioned fluid was inclined to inject into the reservoirs at NE-SW trending strike-slip fault zones, i. e. , TZ45 and TZ82-16 well areas. The current study further claims that the prior karst cavity systems would have been destroyed by intensely compaction during the burial process. However, the siHviving cavity systems may have also been preferential channels for the flow of hydrothermal/burial dissolution fluid, which would have expanded pore spaces. Therefore, great attention shall be paid to the activities of tensional faults under the compression set such as strike-slip fault zones, as well as their conduction effect of hot fluid. By interpolation, it should be attached importance to the superimposition effect of multiple stages of distinctive fluids on the reservoirs, which may be the potential exploration targets.
