The Method for Removing the Factors Affecting Monitoring Parameters of Ultrasonic Fluid Level Sensor and Its Application

摘要: 超声波液位传感器是测量钻井液体积的最主要监测设备。由于在录井作业过程中存在影响超声波液位传感器参数监测的因素，针对传感器的影响、钻井液池体积标定的影响、选择标定方法不正确的影响、钻井作业过程中的影响，提出通过标准化安装、标准化操作减少人为干扰因素发生的概率。通过人工校对法和安装支架改进等手段，排除超声波液位传感器参数监测的影响，让采集数据更准确，预报评价更科学。

Abstract: The ultrasonic fluid level sensor was the most important monitoring instrument for measuring the volume of drilling fluid. There were many factors affecting its monitoring parameters during logging operation. In consideration of the effects of ultrasonic level sensor itself, the volume calibration of drilling fluid pit, the mal-selection of calibration methods and the effect in well drillings, it is proposed that the probability of human interference factor should be reduced by standardized installation and standardized operation. The methods of manual checking and holder installation are used to eliminate the impact on monitoring parameters of ultrasonic level sensor. These practices can make data collection more accurate, and prediction more scientific.
