由减振器、震击器和稳定器组成的井下钻井“三器”,已成为各油田井下钻井工具中必备的工具。文中总结了大庆油田勘探开发多年来的研究和应用钻井“三器”的科研成果,对“三器”的工作原理、基本结构、设计原则、工具类型和使用情况进行了分析。并针对各种工具的使用特点提出亏一些认识体会。 Downhole drilling by the shock absorber, jars and stabilizers, “three”, has become an essential tool in the oil well drilling tools. This paper summarizes the research achievements of Daqing oilfield exploration and development over the years and the application of “three” of drilling, and analyzes the working principle, basic structure, design principles, types of tools and usage of the “three devices.” And a variety of tools for the use of characteristics to make some loss of understanding.
