基于注入压降法的煤层气指标试井试验

为了准确地测出煤层气的指标参数,将注入压降法应用于煤层气指标测试中,应用预先设计好的试验流程及试验设备对煤层进行注水测试.介绍了注入压降在煤层气测试中的应用情况,进行了基于注入压降法的煤层气指标试井试验.试验结果表明,注入压降法的煤层气指标试井试验在煤层气测试中是非常有效、普遍的方法.

Experiment on test well of coal bed methane index based on injection pressure drop method

In order to accurately measure the index parameters of the coal bed methane,the injection pressure drop method was applied to the index measurement of the coal bed methane.The water injection measurement and test were conducted with the pre-designod test pro- cedure and test equipment.The paper introduced the application of the injection pressure drop to coal bed methane measurement and test. An experiment on the test well of the coal bed methane index was conducted based on the injection pressure drop meth...
