我队最近在B-3型钻机上,试用了一种平衡装置,效果很好.可以提高效率,减少一人操作.同时,构造简单,易于制作.尤其是解决了放绳时,压力不均,确保井内压力正常,能减少岩心堵塞.这种平衡装置是利用杠杆作用,使平衡器重量和钻具重量(除轴心压力)相平衡,而卷鼓处于自由状态,跟随进尺,卷鼓回转,则平衡器始终保持平衡.平衡器的构造,如图1所示.主要另件,有前支
Our team recently experimented with a balancing device on the B-3 drilling rig, the effect is very good, which can improve the efficiency and reduce one-person operation, meanwhile, the structure is simple and easy to make, especially when the rope is released, the pressure is uneven, To ensure that the pressure inside the well is normal and the core blockage can be reduced.This balancing device utilizes leverage to balance the weight of the balancer with the weight of the drilling tool (except the axial pressure) while the drum is in a free state, following the footage, rotating the drum, The balancer is always balanced The structure of the balancer, as shown in Figure 1. The main components, the former branch
