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。 During the gas injection well test in the Sebei gas field in Qinghai, due to the limitation of logging technology, there are some difficulties in the conventional gas well profile interpretation method. Through the gas injection profile analysis and data interpretation of 66 wells in 32 wells in Qingbei Sebei gas field, it is found that the output gas from the Sebei gas field is dry gas, which belongs to ultra-low density and ultra-low viscosity fluids. , But also serious sand production layer. Developed a set of gas injection profile interpretation methods suitable for this kind of well, which correctly reflected the output and injection status of each injection well section in the injection well and provided the first-hand dynamic monitoring data for the oilfield development.
