摘　　要：兴城火山岩气藏为存在边底水的复杂气藏。为了分析该气藏底水上升规律,为开发方案设计提供科学依据,在分析其主要地质特征的基础上,首先建立了单井地质模型,然后根据单井地质模型和数值模拟技术研究了储层渗透率、水体大小及水体渗透率、隔层位置及大小、垂直/水平渗透率、单井配产以及储层打开程度等因素对开采效果的影响。通过分析认为渗透率等因素都对气井开采产生了不同程度的影响,开发过程中应综合考虑各种因素的影响,以达到合理开发的目的。该研究为兴城火山岩气藏的合理开发技术对策制定提供了依据,同时亦可为同类气田开发提供借鉴。The volcanic gas reservoirs in Xingcheng Gas Field belonged to reservoirs with bottom water. To analyze the rules of the bottom-water rising principles and provide a scientific basis for the design of development plan, on the basis of analyzing its geological characteristics, a single well geologic model was first established, and then according to the model and numerical simulation, the influences of formation permeability, aquifer sizes and permeability, location and size of the restraining barriers, vertical and horizontal permeability, single well proration and reservoir opening level on production efficiency were studied. Analysis shows that permeability and the other factors influenced the recovery of gas wells in some extent. Every factor should be integratedly considered during the development of gas reservoirs for a rational development. It provides a basis for planning an appropriate development project of Xingcheng Gas Field, and as well as a reference to the similar gas field development.
