  • The Ordovician gas reservoirs in block 9 of the Tahe oil field are carbonate-type fractured-vuggy gas condensate reservoirs. High water content in the later stage of production severely restricts stale production. In this paper, the water seepage mechanism and water pattern of the single well were analyzed, and the water charac-teristics in this area were divided into slow rising type, rapid ascending type, flooding type and no water type. The results showed that the gas flow capacity of fractured-vuggy reservoirs is higher than that of fractured reservoirs, and the gas flow capacity in fractured reservoirs is more obviously controlled by liquid facies. There are three water intrusion modes including vertical fracture communication, fracture and cave communication, and fixed volume. Some countermeasures were proposed respectively.
