近钻头测斜器(ABI)用于石油钻井中随钻测量实际井眼轨迹,是随钻测量的重要组成部分。该文对随井钻探ABI模块的温度特性进行了分析与建模,针对敏感元件和电路板的温度差异,提出了确定温度模型参数的实验及数据处理方法,通过实验验证了温度补偿的效果。在30℃~150℃的温度范围内,加速度计的测量精度达到5×10-4 g,完全满足ABI姿态角测量的要求。
Near-bit inclinometer (ABI) is used to measure the actual well trajectory while drilling in oil drilling. It is an important part of measurement while drilling. This paper analyzed and modeled the temperature characteristics of well drilling ABI module. According to the temperature difference between sensitive components and circuit board, the experiment and data processing method to determine the temperature model parameters were proposed. The effect of temperature compensation was verified by experiments. In the temperature range of 30 ℃ ~ 150 ℃, the accuracy of the accelerometer is 5 × 10-4 g, which fully meets the requirements of ABI attitude angle measurement.
