摘　　要：传统的钻井设备未考虑外界负载变化的影响,导致稳定性差,为此,提出一种考虑外界负载变化的自调节元件响应控制方法。在设计自调节元件结构过程中,采用单锥、双锥与浅锥3种模式设计冠部结构轮廓,利用被动式液压结构反馈结构组成切削深度控制结构,通过布齿方法与布齿密度设计切削结构,完成自调节元件结构的优化。并分析自调节元件所受外部负载以及自调节元件冠部结构钻压施加情况,构建自调节元件与外部负载相互作用模型,实现自调节元件响应控制。由测试结果可知,该控制方法可减少自调节元件的磨损,提高机械转速,提升了钻井过程中钻井设备自调节元件工作状态下的稳定性,适用于复杂地质条件下的钻井作业。Traditional drilling equipment does not consider the influence of external load change,which leads to poor stability.Therefore,a response control method of self-adjusting element considering external load change is proposed.In the process of designing the structure of self-adjusting element,the crown structure profile is designed in three modes:single cone,double cone and shallow cone,the feedback structure of passive hydraulic structure is used to form the cutting depth control structure,and the cutting structure is designed by tooth arrangement method and tooth arrangement density,so that the structure of self-adjusting element is optimized.The external load on the self adjusting element and the weight on bit of the crown structure of the self-adjusting element are analyzed,and the interaction model between the self-adjusting element and the external load is built to realize the response control of the self-adjusting element.According to the test results,this control method can reduce the wear of self-adjusting elements,increase the rotating speed of machinery,and improve the stability of self adjusting elements of drilling equipment in the working state during drilling.It is suitable for drilling operations under complex geological conditions.
