摘　　要：青海涩北气田的注产气井测试中,由于测井技术的局限性,常规注气井剖面解释方法存在一定的困难。通过对青海涩北气田32口井66井次注产气剖面的测试及资料解释分析,发现涩北气田产出气体为干气,属超低密、超低粘的流体,井下多有积水,而且产层出砂严重。研究出了一套适合此类井的注产气剖面解释方法,正确反映了注产气井各射孔井段的产出注入状况,为油田开发提供了第一手动态监测资料。For gas-production well testing in Qinghaisebei gas reservoir, the conventional gas-production profile testing technique has some difficulties in some degree due to its limitation. 66 gas-production profile testings in 32 wells and their data analyses in Qinghaisebei gasfield have proved that the gas in this field is dry and the fluids are super low dense and super low viscous;there are much flowages in downhole, and sand production is also serious. We worked out a new method fit for this kind of well's gas production profile explanation. The method is reasonable and correctly reflects output and injection of gas-injection-production well's perforated intervals, thereby providing first hand dynamic monitoring data for gasfield development.
