    粘滑振动是一种典范的非线性自激振动,是钻杆在钻井历程中面对的最为常见的风险,发作概率高达40%。是形成钻杆和钻具组合疲倦以至断裂,钻头磨损的主要原因。粘滑振动还会招致钻头偏离希冀的钻井标的目的,大概破坏井壁使井壁坍塌。粘滑振动历程中钻头转速霎时到达很大值,扭矩颠簸也很大。

 

   软扭矩掌握是一种针对粘滑振动停止自动掌握的办法,可以有效地抑止粘滑振动,基于顶部驱动钻井手艺的空中掌握手艺,硬件构造简朴,无需增加任何井底装备,与现有变频器顶驱PLC控制系统无缝集成,变频器与软扭矩控制器经由过程CAN总线停止毗连,变频器可以将驱动机电确当前转速和扭矩反应到软扭矩控制器,软扭矩控制器可以将掌握转速传输到变频器对钻杆停止掌握。

 

Soft torque control

The stick-slip vibration is a typical Nonlinear self-excited vibration, which is always met while drilling, and highly 40% probability. It is the main cause for drill pipes and strings damaged, drill bit worn, and it also make bit deviate its expected drilling direction, or damage well wall. The rotary speed of drill bit reach the max., and more vibration while stick-slip vibration.

 Soft torque control is a effectively method to control stick-slip vibration, which is based on ground control technology of TDS drilling. Without adding any bottom equipments, its simple construction is assembled seamless with transformer PLC control system, and transformer is connected to soft torque controller through CAN cable, then transformer feedback current rotary speed and torque of motor to soft torque controller, which transfer instruction to transformer to control the drill pipes.
