摘　　要：为确定CO2气源井射孔各层段产气及产水状况,评价射孔层段储量动用程度,以及为气源井制定科学生产合理的生产制度,首先通过高精度压力计测取气源井的流温、流压资料,了解全井温度、压力梯度情况,确定井筒流体相态;然后采用高压气体密闭测试工艺,根据测得的流体相态,利用氧活化测井技术和PLT测井技术实现CO2气源井的产能测试,对气源井产能状况进行初步评价,解决了CO2气源井产气剖面测井难题。In order to determine the gas and water production status of perforated intervals in CO2 gas source wells,evaluate the degree of reserves utilization in perforated intervals,and to formulate a scientific and rational production system for gas source wells,two steps were taken.Firstly,the flow temperature and pressure data of gas source wells are measured using high precision manometer to obtain the temperature and pressure gradient of the whole well,and to determine the wellbore fluid phase state.Secondly,oxygen activation logging technology and PLT logging technology are used to realize the productivity test of CO2 gas source wells through enclosed test process according to the measured fluid phase state.A preliminary evaluation of the productivity of gas source wells has been conducted and solved the problem of logging of gas production profile in CO2 gas source wells.
