我厂试制的半导体双感应测井仪能同时并测深、中两种探测深度的感应测井曲线,可与浅侧向测井曲线组合,为求解地层真电导率和估计侵入影响提供所需资料。经过现场试验并与美国同类型仪器对比表明性能良好。仪器的技术指标、试验结果和解释成果可参见《测井技术》1978年第三期,本文仅就双感应测井仪的井下电路部分的特点
The semiconductor dual-induction logging tool prototyped by our factory can simulate and sound the depth simultaneously. The two kinds of sensing logging curves at the detection depth can be combined with the shallow lateral logging curves to provide the required solution for solving the true conductivity of the formation and estimating the impact of intrusion data. After the field test and comparison with the same type of instruments in the United States showed good performance. Instrument specifications, test results and interpretation of the results can be found in “Logging Technology” 1978 the third period, this article only on the dual induction logging instrument downhole circuit features
