摘　　要：针对千米定向钻机给进工况对给进系统的要求,通过对现有钻机给进控制的分析对比,利用负载敏感的基本原理,开发出千米定向钻机的负载敏感给进液压系统。采用系统仿真软件AMESim对千米定向钻机的给进液压系统进行建模与仿真,并通过实验室测试及现场实验。结果表明:该给进控制系统具有流量与负载无关控制能力,有较好的调速性能,能够较好地满足千米定向钻机使用要求,可为同类钻机设计及实验提供理论依据和方法。Through analyzing the requirements of kilometers directional drilling rig feeding condition to feeding system and con- trasting feed control of existing drill, a load-sensitivity feeding hydraulic system was designed for kilometers directional drilling rig u- sing load sensitive principle. The feeding hydraulic system model of kilometers directional drilling rig was built by the system simula- tion software AMESim. The tests in laboratory and field show that there are no relation between flow and load in the feeding control sys- tem, and it is good at control performance, it can meet the operating requirements of kilometers directional drilling rig. It provides theory and methods for the drill design and test.
