贵州石油勘探指挥部泥浆试验室和贵州大学物理系等于1975年5月开始共同研制钻井液参数自动检测仪。这种自动检测仪的设计要求是:将钻井泥浆的比重、粘度、切力、失水、泥饼、PH值和温度等主要参数先转换为电参数后实现其自动连续测量和数字显示。仪器由一次电压转换器和二次检测仪两部分组成。1976年 Guizhou Petroleum Exploration Command Mud Laboratory and Guizhou University Department of Physics equal to start in May 1975 jointly developed drilling fluid parameter automatic detector. The design requirements of this automatic detector are as follows: First, the main parameters of drilling mud, such as specific gravity, viscosity, shear force, water loss, mud cake, PH value and temperature are converted to electrical parameters to realize automatic continuous measurement and digital display. The instrument consists of a voltage converter and secondary detector in two parts. 1976
