Abstract: The western Block B of Amu Darya right bank has great potential for natural gas development. But the current exploration degree is relatively low, and gas and water distribution is not clear, which restricts the additional well allocation and follow-up development plan making. Based on the integrated use of logging and test results, the paper analyzes the relationship between gas and water in gas reservoirs, establishes a gas-water identification standard for the early exploration stage in the study area. It is considered that a pattern of “gas above and water below” exists in single wells vertically, but several gas-water systems are found regionally and there is no unified gas-water contact. The paper presents 3 gas-water distribution patterns for gas fields in western Block B of the right bank of Amu Darya, namely structural laminar edge-water gas reservoir, structural laminar bottom-water gas reservoir and structural lithological edge-water gas reservoir; and determines the planar distribution characteristics of each pattern, which could provide references for the study on gas-water distribution in multi-trap, complicated gas reservoirs in the similar carbonate rocks
