摘要： 阿姆河盆地右岸B区西部具有巨大的天然气开发潜力，但目前勘探程度较低，气水分布规律尚不明确，制约了补充井位的部署及后续开发技术政策的制定。综合利用测井和测试解释成果，开展气藏气水关系分析，建立了适用于研究区勘探初期阶段的气水识别方案。认为单井纵向上气水分布仍然遵循“上气下水”的模式，但区域上存在多个气水系统，无统一气水界面；提出了阿姆河盆地右岸B区西部气田群的3种气水分布模式，即构造层状边水气藏、构造层状底水气藏、构造岩性边水气藏；明确了各种模式在平面上的分布特征，可供同类型碳酸盐岩多圈闭复杂气藏气水分布研究参考。

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
