摘要
在地质勘探、煤矿开采、石油钻井以及地热资源开发中,近钻头随钻测量在实时探测工具姿态等工程参数和地层的地质参数、实施导向钻井中发挥着重要的作用。本文介绍了随钻测量系统的工作原理,重点描述了姿态角的物理模型以及解算方法;同时,基于国产化耐高温的可编程逻辑门阵列(FPGA)芯片、三轴加速度传感器、三轴磁阻传感器,进行了近钻头随钻测量系统的设计。测试实验结果表明,系统性能指标可满足实际工程应用。
In geological exploration,coal mining,oil exploration and geothermal resource development,near‑bit MWD plays an important role in real‑time detection of engineering parameters such as tool attitude and formation geological parameters,and implementation of guided drilling.This paper introduces the working principle of MWD system focusing on the physical model of attitude angle and its solution,at the same time,based on the domestic high temperature resistant programmable logic gate array(FPGA)chip,three‑axis acceleration sensor and three‑axis reluctance sensor,the near bit MWD system is designed.The test results show that the performance index of the system can meet the practical engineering application.
