摘　　要：噪声测井主要用来检查套管外窜槽、固井质量以及定性确定套管外出水和出气层的位置等。TSH噪声测井仪由短节头、扶正器、电子线路、噪声传感器和温度传感器共五部分组成,可记录噪声频率范围为100 Hz^20 000 Hz,温度范围为5℃~150℃。与GKL仪组合测井时,可同时记录噪声、井温、套管接箍及自然伽玛信号。根据井下情况,TSH既可进行连续测量,也可进行点测。TSH主要通过噪声频谱确定套管外窜流情况,但井温也是研究套管外窜流情况的一个重要参数。Noise logging is principally used for inspecting outside casing channeling,evaluating cementing quality,confirming the position of aquifer and gas reservoir production qualitatively,and so on.TSH logging tool comprises lift sub-head,centralizers,electronic circuit,noise sensor and temperature sensor.The recording noise frequency ranges from 100 to 20000 hertz and the recording temperature ranges from 5 to 150 centigrade.Combining with GKL logging tool,TSH logging tool can record noise,well-temperature,casing coupling signal and natural gamma ray.According to the borehole condition,TSH logging tool can take point measurement as well as continuous measurement.Noise spectrum is the most effective way to inspect outside casing channeling,but the recording well-temperature is also another important parameter to study outside casing channeling.
