%X Detailed studies of homogenization temperatures of fluid inclusions, distribution and geochemistry characters of hydrothermal minerals provide insights into chemical, distribution and flowing 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 surviving 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.
