The spiral drill collar is one of our product families. Three RH spiral grooves is
made in outside surface of drill collar in order to reduce the contract area with the
well face and the steering resistance, which can prevent differential pressure
sticking. The weight of spiral drill collar is 4% lighter than drill collar of the same
size. The shapes of both ends are the same as round drill collars. Spiral drill
collars are classified into typeⅠand type Ⅱ according to the difference of spiral
grooves.
