摘要 冲击回转钻进技术的设想始于欧洲。从上世纪五十年代开始，在美国，加拿大和前苏联才研制出几种具有实用意义的液动冲击器。我国从1958年底开始在原地质矿产部勘探技术研究所对液动冲击回转钻进技术进行研究circumgyrate drilling of fluid move concussion and fluid move impulsion implement of counteractive of valve style,study working principle and frame characteristic of fluid move impulsion implement of counteractive of valve style.And it advances the measure that account the wallop and concussion frequency.Overpass the analysis,it indicate that the fluid move impulsion implement of counteractive of valve style is the same with the terrane that whose rigidity is middle or upwards.Besides it should accretion the arrange quantity of slop to the best of its abilities and adhibits clash spring of the greater limit to exert the excellence of impulsion implement.It also makes detailed analyzed account and checking computations in allusion to the key part of the impulsion implement,and analyses the technic economy effet of the impulsion implement.The text do mianly these work: 1)expound circumgyrate drilling of fluid move concussion particular. 2)introduce diversified impulsion implement particular. 3)analyse orking principle and frame characteristic of fluid move impulsion implement of counteractive of valve style. 4)capability analysis and parameter account of fluid move impulsion implement of counteractive of valve style. Key words: fluid move, circumgyrate, drilling, counteractive ,concussion implement 目录 摘要 1 Abstract 2 第一章 液动冲击回转钻探 1 1．1概述 1 1．2冲击回转钻进的实质和特点 2 1．3冲击回转钻进的应用范围 3 1．4冲击回转钻进的发展概况 4 1．5液动冲击回转钻在地质岩心钻探中技术经济效益 6 第二章 液动冲击器 8 2．1冲击器的种类 8 2．2 反作用式液动冲击器 15 2．2．1 反作用式液动冲击器的结构原理 15 2．2．2 反作用式液动冲击器的结构特点 15 2．3 阀式反作用液动冲击器性能分析及参数计算 16 2．3．1 功率特性及活塞冲锤运动特性分析 16 2．3．2 参数计算 16 2．4 本章小结 22 第三章 ГВМС—5型液动锤 23 3．1 ГВМС—5型液动锤工作原理及特点 23 3．2 冲锤弹簧设计和计算 24 3.2.1原始条件的确定 24 3．2．2．参数计算： 25 3.2.3验算 27 第四章 液动冲击回转钻进的发展展望 27 4．1 液动冲击回转钻进的发展方向 27 4．2 基础理论方面的重大课题 30 4．3 应用研究 30 第五章 液动锤的仿真分析 31 致谢 35 参考文献 36 第一章 液动冲击回转钻探 1．1概述 采用冲击回转钻进技术的设想始于欧洲。1867—1887年期间，一些企图代替钻杆冲击钻的潜孔式液动冲击器相
