Analysis of the influence factors of dual lateral logging quality and its solution

基于双侧向测井的特殊性,导致影响双侧向测井的因素很多。本文依据测井工作原理,针对现场出现问题,研究测井回路、自然电位、深驱动板、带通滤波器等主要影响因素提并出的解决方法,通过室内模拟和现场测试验证其正确性。结果表明:室内模拟刻度时测得的电压、电流符合电压、电流采样值的工作范围;现场测井时测得的电压、电流符合测井要求的质量;通过室内模拟刻度和现场测试验证了提出解决方法的正确性。

This paper describes the particularity of the dual lateral logging tools and the factors that influence its effectiveness. According to the principle of the tools,against the field problems,we research the main influence factors of logging loop, SP, deep driver board, bandpass filter,give solution to the problem and through laboratory simulation and field testing to verify its correctness. Results show that:indoor analog scale while the measured voltage and current values meet the voltage and current sampling value scope of work;in the field logging measured voltage and current values meet the quality requirements;Through the indoor analog scale and field tests verify the correctness of proposed solutions.
