摘　　要：针对当前塔里木油田见水气井产出剖面测不准、出水层位识别难、出水量算不准的问题,开展多源距示踪流量组合测井仪设计研发。在现有示踪仪器基础上,通过优化传动机构和源腔密封,增加管壁内部穿孔导流喷射等,将喷射口调整到仪器顶部,缩短示踪喷射口到探头之间的距离。通过检测电路与探头一体化封装及双探头设计,组合原有伽马仪,实现了三伽马探头测量。经4井次下井试验,论证了多源距示踪流量组合测井仪的可行性,实现了见水气井出水点的准确识别和出水量的定量计算,能够为库车山前低产液井产出状况作出精准评价。In view of the current problems of inaccurate measurement of the production profile of water-cut gas wells in Tarim oilfield,difficulty in identifying the aqueous horizon and inaccurate calculation of water output,the design and development of multi-source tracer flow combined logging tools were carried out.On the basis of the existing tracer instrument,by optimizing the transmission mechanism and the source cavity seal,and adding the perforated diversion injection inside the pipe wall,the jet port is adjusted to the top of the instrument to shorten the distance between the tracer jet port and the probe.Through the integrated packaging of the detection circuit and probe and the design of dual probes,the original gamma meter is combined to realize the measurement of three gamma probes.Through the four wells of the downhole test,the feasibility of the multi-source spacing tracer flow combined logging tool was demonstrated,and the accurate identification of the water outlet point and the quantitative calculation of the water output of the water gas well were realized,which could make an accurate evaluation of the output of the low-yield liquid well in front of Kuqa mountain.
