摘要
产水气井水侵动态的研究是有水气藏生产管理中最为基础的工作。自2井是缝洞型有水气藏的典型代表,详细研究其水侵动态和产水规律具有重要的工程和理论意义。在核实储量的基础上,详细地研究了自2井的水体能量,应用非线性自动拟合法、视地质储量法等多种气藏工程方法对自2井的水侵动态进行了研究,并分析了地下溶洞对气井生产的影响,指出了井底溶洞的储水作用是保持该井后期长期稳产的根本原因之一。
Water-invasion performance research of water-producing gas wells is the foundation of water-bearing gas reservoir management. Well Zi 2 is a typical fractured-vuggy water-bearing gas reservoir. Studying its water-invasion performance and water-production rule is very significant. On the basis of reserves verification, the water-body energy of well Zi 2 has been researched. Moreover, the water-invasion performance has been studied by gas reservoir engineering methods such as nonlinear auto-matching and apparent geologic reserves. This paper analyzes the effects of underground solution cavity on gas productivity, and points out that the water-storage capability of downhole solution cavity is one of the fundamental causes of keeping a long-term stable production during later development.
