煤层气井注入/压降试井测试中有关技术问题探讨

Discussion on technical problems for injection/fall-off well test in the coalbed methane well

根据我国煤层气勘探开发中注入 /压降试井测试技术的应用情况 ,结合多年从事煤层气井试井工作的实践经验 ,从实际应用的角度出发 ,对试井设计、施工工艺及数据分析中所涉及的一些技术问题进行研究和探讨 ,并提出相应的改善措施和建议 。

Based on the actual application of injection/fall off well test for the coalbed methane exploration and development in China,combined with practical experience for many years,from the view point of application,some technical problems for well test design,process of construction and data analysis are studied and discussed in this paper,it is presented that some suggestions and measures of improvement,and provided important basis for construction of well test in future.
