针对目前气田开发及试井分析技术的现状,本文考虑井筒气水两相流动对地层气水两相渗流的影响,通过建立井筒/地层气水两相组合数学模型并用数值方法实现对其的求解,提出了气水井试井的新方法,并对将组合模型用于气水井试井分析的特殊的处理技术进行了研究和阐述。实际气水井压力恢复分析结果表明,相对于传统的试井分析技术,本文提出的气水井试井新方法解释结果更可靠,解释的特征更多,应用面扩大,为气水井试井分析提供了科学的依据和有效的手段。 In view of the present situation of gas field development and well testing analysis technology, this paper considers the influence of gas-water two-phase flow in the wellbore on the formation gas-water two-phase seepage. By establishing the mathematical model of wellbore / formation gas-water two-phase combination and solving it by numerical method , Put forward a new method for well testing of gas well, and studied and elaborated the special treatment technology that combined model for well test analysis of gas and water well. The results of pressure recovery analysis of actual gas-water well show that compared with the traditional well-test technology, the new interpretation method of gas-water well test is more reliable, more explainable features and wider application area, Scientific basis and effective means.
