【摘要】：旋转导向钻井技术是现代钻井的先进技术,在观测井眼轨迹有着强大的优势,同时随着数字信号处理技术的迅速发展,为人们准确观测井下的姿态参数(井斜角I、工具面角T以及方位角A)带来了便利。根据钻井技术的要求,定制了一种加速度计传感器作为测量元件。由于传感器输出的是电流信号,因此设计一种信号调理电路将其转换为电压信号进行放大并进行电压转换,经过电压跟随器送入DSP内部的ADC进行采集。DSP芯片选用TI公司的TMS320F28335,硬件电路除了信号调理电路外,主要由电源供电电路、时钟电路、复位电路以及JTAG口下载电路、LCD显示电路组成。在软件方面注重采用模块化设计,主要包括中断子程序、AD采样设置、软件滤波子程序、角度解算子程序以及显示子程序等。制作PCB电路后,搭建了测试系统与调校仪进行了对比测试,结果显示测量系统达到了设计的要求。
[Abstract]:Rotary steering drilling technology is an advanced technology in modern drilling. It has a strong advantage in the observation of borehole trajectory. At the same time, with the rapid development of digital signal processing technology. It is convenient for people to accurately observe the downhole attitude parameters (well angle I, tool face angle T and azimuth angle A), according to the requirements of drilling technology. A kind of accelerometer sensor is designed as the measuring element. Because the sensor output is a current signal, a signal conditioning circuit is designed to convert it to voltage signal for amplification and voltage conversion. The TMS320F28335 of TI company is used to collect the ADC in the DSP through the voltage follower. The hardware circuit is not only the signal conditioning circuit but also the signal conditioning circuit. It is mainly composed of power supply circuit clock circuit reset circuit and JTAG port download circuit LCD display circuit. In the software we pay attention to the modular design mainly including interrupt subroutine. AD sampling setting, software filter subroutine, angle resolution operator program and display subroutine, etc. After making PCB circuit, the test system is built and compared with the calibrator. The results show that the measurement system meets the requirements of the design.
