Design And Implementation Of The Ground System Based On UCOSIII System Of C/O Spectrum Logging System

The main function of this system is to receive and process the detected radionuclide spectra,calculate and analyze the formation and well conditions according to the spectra,and analyze the information of oil-water saturation,lithology data and porosity by calculating C/O and Si/Ca parameters.On the basis of the existing ground system functions,the automatic control function of neutron generator and the three-source spectrum stabilization function are added to improve the accuracy of the effective efficiency of neutron generator and the spectrum stabilization algorithm(including peak drift correction)for the acquisition of gamma-ray spectrum.On the one hand,it is the automatic control of neutron generator,which not only facilitates the operation of logging crew,but also reduces the technical and skilled requirements of logging equipment operators.At the same time,it improves the consistency of effective efficiency of neutron generator,improves the accuracy and consistency of logging data,and improves the accuracy of logging data judgment.On the other hand,the spectrum stabilization algorithm is improved by three sources to improve the authenticity and accuracy of the energy spectrum data collected,further improve the accuracy of the data collected by the equipment and the analysis results,reduce the possibility of misjudgment,and reduce the economic and human costs caused by misjudgment.
