基于负载敏感技术的定向钻机给进系统研究

摘要

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.%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。
