摘要
设计了一种基于应变测试法的钻井工程参数随钻数据采集系统。采用四应变片全桥方式,可以对钻压、扭矩、侧向力、环空压力等钻井工程参数进行随钻测试。数据采集系统采用ADμC8xx系列单片机为主控制器,另外设计了相应的外围信号调理模块、数据存储模块、数据通信模块和电源模块等。实验结果说明该数据采集系统用于井下钻井工程参数的测试是可行的。
The authors of the paper designe a data acquisition system of drilling engineering parameter while drilling based on strain measuring technology. By means of four strain gauge full-bridge mode, drilling engineering parameters, such as drilling pressure, torque, side pressure and annular pressure etc. can be measured while drilling. The data acquisition system adoptes ADμC8xx series single chip as main controller, in addition, peripheral signal processing circuit, memory module, communication module and power supply module and so on are designed, too. The experimental result suggests it is feasible that this data acquisition system is applied to measure well drilling engineering parameters.
