Description
Technical field
The present invention relates to the anti-sliding drill tools of hydraulic type that a kind of horizontal well horizontal segment drill string is sent to.
Background technology
In drilling engineering, horizontal well has the economy of excellent benefit, but the technical difficulty of horizontal well is also larger.It is recurrent phenomenon in horizontal well drilling process that horizontal segment drill string takes off pressure, the generation of de-pressure phenomenon is mainly because the frictional force between the drill string of horizontal segment and borehole bottom is excessive, eliminate the pressure of the drill effect that upper drilling string provides, directly cause the drill string of horizontal segment to send to, seriously constrain the development of horizontal well drilling technology.
Existing horizontal well antifriction instrument is little, primarily of installing the antifriction short circuit of roller and producing the hydroscillator of continuous shaking, the static friction of drill string and well is become rolling friction by the former, the static friction of drill string and well is become dynamic friction by the latter, serves the effect of antifriction all to a certain extent.But above-mentioned two kinds of instruments are all only try every possible means on reducing friction, and do not consider the problem initiatively applying the pressure of the drill, along with the increase of horizontal section length, accumulation frictional force still can overcome the pressure of the drill, and the problem that drill string sends difficulty to is still given prominence to.Based on above technical background, spy of the present invention provides a kind of hydraulic type anti-sliding drill tools.
