摘　　要：台阶式注入流量测试是直接针对煤层及围岩进行的测试方法 ,能比较准确地获得煤层破裂压力、破裂梯度、最小原地应力、最大注入量 ,为恒流量注入Step injection test is a direct test method for the coalbed and the surrounding bed.By using this method,the fracture pressure,fracture pressure gradient,minimum local crustal stress and the maximum injection rate would be determined exactly.This method would supply many exact parameters for the fracturing design and the injection/falloff test.

关 键 词：煤成气 钻柱地层测试 注入量 闭合应力 破裂压力
