【摘要】 煤层气井的关井测压和放压试验，是一项有利于进一步了解煤储层特性和产气条件的工作，在我国以往的排采工作中很少见到系统的资料，本文根据铁法煤田 DT3井关井测压和放压试验成果结合实际予以探讨，希望对煤层气资源的开发，有所裨益。更多还原

【Abstract】 Shut－ in pressure measuring and pressure releasing test of coal bed gas well contributed to further understand features of coal reservoir and gas－ formed conditions. This kind of information very few in our country. Based on the informations of pressure measuring and pressure releasing test in DT3 well of Tiefa coal－ field, probe into the capacity of coal reservoir and gas－ formed conditions and so forth features, may be helpful to the exploitation of coal bed gas resources.更多还原
