The Research And Process On Induction Logging Signals

With the development of petroleum industry and requirement of oil-gas exploitation, detection of thin beds plays an important role in increasing oil reservoir. But the traditional induction-logging tools, which equipped with log well are influenced by borehole, shoulder-effect and mud their vertical resolution can not meet our requirement. Therefore it is necessary to ameliorate the traditional induction logging tool to improve its resolution and deeper detection depth.This paper studies the electric circuit and signal processing technology of the traditional induction logging tool. It also gives the integration research to the induction logging tool. This paper describes the design of the middle and senior depth induction logging, achieving the collection and magnify of the induction signal. It achieves the AC/DC switch and the function of uploading data.The study successfully realizes communications among the ground system and the modules in well, with high speed and high resolution. It comes true the greatly controls much resource of degrades cost, reduces the size, improves reliability. In the same time, it gives the basic research of the ground signal process technical. It is mainly to doing preliminary research of the correcting of the skin effect and the scale.
