| 摘 要： | 针对井眼轨迹的测量问题,根据测量仪器的输出信号与钻具姿态信息存在一定的三角函数关系,提出了一种工具面角模拟解算方法.分析了工具面角数字计算方法及其误差,基于模拟函数发生器构造了一种新颖的反正切函数求解电路,可以直接获取工具面角.对不同井斜角和工具面角的情况下进行了试验测试,数据分析表明,该方法可行,并具有较高的精度,可用于快速的姿态参数解算.

| Abstract: | In order to solve the problem of measuring the well trajectory,an analog-solving method of tool-face angle was proposed according to the trigonometric function relationship between the output signal of measuring instruments and the attitude information of drilling tool. With the method,the digital calculation method of tool-face angle and the measurement errors were analyzed. Based on the analog function generator,a novel solving circuit of arctangent function was constructed,by which the tool-face angle ca... |
