Development of Hydraulic Motor Automatic Driller
摘要
Abstract
A hydraulic motor auto-driller device is one of the important equipments of hoisting system of drilling rig.The auto-driller device of drawworks can perform emergency operation and improve the maximum drill string weight when the main system fails.Two modes of constant WOB and constant speed bit feeding can be selected according to the requirement of drilling operation to complete the setting of auto-driller.By setting the constant torque and drawing the drum inversely,we can make the system realize the automatic adjustment of feeding speed and safety protection in the drilling process to keep pressure and speed constant during drilling operation.The device uses the combination of computer and hydraulic control technologies to achieve hydraulic motor accuracy control and realize high accuracy automatic drilling.The control system completes information integrated processing and bit feeding control during drilling operation through receiving signals of continuous external WOB measuring and hydraulic motor speed detection unit by the PLC programming technology.The device is worth popularizing and applying after the application of 17 sets of drilling rigs and more than 30 oil wells in oilfield.关键词
