随着石油钻井的井深不断增加及近海油田的开发,钻井费用也随着急剧上升,这就促使西方国家积极地去研究、探索更安全和更经济的钻井技术。本文综述了国外随钻随测技术的发展近况,主要介绍四种不同的传榆方法—泥浆脉冲传输系统、有线传输系统、声波传输系统、电磁传输系统以及几种随钻随测仪器的系统原理和结构。对已形成产品的泥浆脉冲系统,作较详细的介绍。文章最后指出,随钻随测技术的研究和应用,在国外已引起普遍的重视。
With the increasing depth of oil drilling and the development of offshore oilfields, the cost of drilling has risen sharply, prompting Western countries to actively explore and explore safer and more economical drilling techniques. This paper summarizes the development of LWD technology in foreign countries, and mainly introduces four different methods of SBS: mud pulse transmission system, cable transmission system, sonic transmission system, electromagnetic transmission system and system principle of several LWD instruments And structure. Have formed a product of the mud pulse system for a more detailed introduction. Finally, the article points out that the research and application of measurement while drilling technology has drawn widespread attention abroad.
