摘　　要：大牛地气田为低渗致密气藏,具有单层产能低和多层叠合连片的特点,大部分井采用单层测试,合层开采。利用考虑垂直管流压降法,从理论和实际对多层合采井产能进行了分析和研究,结果显示,气田内合层开采井全井段无阻流量仅略小于各个层段的无阻流量之和,在开发过程中基本可以忽略。Daniudi gas field is a low permeability and tight gas reservoir with low single layer yield and superimposed multilayer. Most wells adopted single layer testing and multilayer extraction. By using the calculation method of vertical conduit flow draw-down, the deliverability of commingled producing wells was analyzed and studied from the theory and practices. According to the re-search, absolute open flow （AOF） of commingled producing wells is only slightly less than the total of intervals. Accordingly, the dif-ference can be ignored in the development process of Daniudi gas field.
