摘　　要：长期以来,油气勘探与钻井业对随钻数据传输技术进行了不懈的研究,产生了泥浆脉冲、电磁波、声波等无线数据传输技术及各类有线数据传输技术,各种传输技术都有自己的局限性,本文阐述了在钻井过程中使用应力波通过钻柱实时传输井下数据的关键技术,并介绍了应力波在钻柱传输特性,信号发送与接收,数字通讯及强噪声背景下微弱信号的混沌振子检测等方面的研究成果以及克拉玛依钻井工艺研究院研究的应力波MWD。Oil and gas exploration and drilling industry proceed unremitting research on LWD data transmission technology for long-time,and mud pulse, electromagnetic wave, acoustic and other wireless data transmission technology were produced. Various transmission technology has its own limitations. This article elaborated the key technology that uses stress waves through the drill string downhole data real-time transmission in the drilling process.The stress wave propagation characteristics in the drill string, signal transmitting and receiving, digital communication and strong background noise weak signal detection by chaotic oscillator and other aspects of the research results and Karamay Drilling Technology Research Institute Research on stress wave MWD were also introduced in the paper.
