摘　　要：针对阿姆河右岸B气田广泛发育裂缝、储层非均质性强和气水关系复杂所造成的单井合理配产难题,通过因素综合分析,将单井产能的主控因素概括为物性因素、裂缝因素和底水因素;并建立特征参数对其进行了定量表征。分析特征参数与气井产能的关系发现:储层物性和裂缝发育程度主要影响气井的无阻流量,储层各向异性、裂缝发育程度和水体活跃程度主要影响气井的配产比。在此基础上进行了气井分类;并给出了相应气井的合理配产比,为气井合理配产提供了依据。The extensive existence of fractures, high degree of reservoir heterogeneity, and extreme complexity of gas-water relationship have gained a great difficulty to the determination of the rational production of the gas wells in B Gas reservoir in the Right Bank of Ainu Darya, Turkmenistan. Based on comprehensive analysis method, the key controlling factors on single well deliverability were generalize to be the physical property of the reservoir, fracture, and the bottom water, after which the characteristic parameters were introduced to the quantification of each factor. Through the establishment of the relationship between each parameter and the single well deliverability, the AOF of the gas well was observed to be mainly controlled by the physical property of the reservoir and the develop- ment level of and fracture ; meanwhile, the production proration mainly controlled by the anisotropy of the reservoir, the development level of and fracture, and the activity of the bottom water. The wells were classified on the basis of the key controlling factors and the production proration of each category was presented, which would be a great facilitation to the evaluation of gas well productivity of the complex carbonate gas reservoirs.
