在几何因子理论的基础上,运用感应测井仪线图系和反褶积滤波器理论结果研制了感应测井过程的模拟仿真实验装置,其结果与计算机数字仿真相比更接近于实际测井情况,该装置还可用于学生测井仪器课的实验,使学生更好地掌握感应测井理论,达到了理论和实验相结合的目的.本文进一步介绍了它的线圈系和反褶积滤波器的数学模型、硬件电路和仿真过程,如果对该装置的仿真过程稍加改进,它还可满足其它类型的感应测井仪的模拟仿真的需要.
Based on the theory of geometrical factors, the simulation and experimental device of induction logging is developed based on the theory of induction logging line system and deconvolution filter. The result is closer to the actual logging than that of computer numerical simulation This device can also be used in the experiment of student’s logging instrument class so that students can better grasp the induction logging theory and achieve the goal of combining theory and experiment. This paper further introduces the mathematical model, hardware circuit and simulation process of its coil system and deconvolution filter. If the simulation of this device is slightly improved, it can also meet the needs of other types of induction logging tools need.
