At present, the cleanout tool that designs for this problem is arranged also, be generally the drill string that utilizes with spiral or V-type conduit as cleanout tool, play the purpose of removing landwaste by the drilling rod rotation.But the instrument that adopts is more single, and conduit mostly is conventional screw type or V-type, causes the eddy flow effect in the pit shaft comparatively general, can not reach the effect of effective removing landwaste.
The utility model content
The utility model is on tubing string mechanics and hydromechanical theoretical foundation, for the problem that produces cutting bed in the current oilfield horizontal well drilling process, purpose from the righting effect that improves cutting bed elimination efficiency and horizontal drilling rod provides a kind of efficient net horizontal section cutting bed cleanout tool.
The technical solution of the utility model is as follows:
A kind of net horizontal section cutting bed cleanout tool, it is formed by several spiral removers and local acclerator complex configuration, described spiral remover and local accelerator are the cylinder of the internal run-through of an end band pin thread, an end band box, they are installed separately on drillstring in horizontal section, and form one group by laying a local accelerator in the middle of two spiral winding 102, on the horizontal segment drill string, arrange at a certain distance one group.
Be furnished with a plurality of skewed slot helical rings on the described spiral remover, evenly distribute along circumferential surface, the drill bit direction be the importer of skewed slot helical ring to, the opening yardstick of its import greater than the outlet yardstick, skewed slot helical ring quantity is decided with design; Described spiral remover be provided with the spiral winding away from drill bit drilling fluid exit, described spiral winding adopts the half elliptic design, is distributed between the skewed slot helical ring, size and the quantity of spiral winding are decided with design.
Be furnished with many oblique bar shaped accelerated bands on the described local accelerator, its width and quantity are decided with design.
This cutting bed cleanout tool is combined according to certain cooperation configuration by a plurality of spiral removers and local accelerator, is installed on the net horizontal section drill string according to block position, and G.I.H can play the effect of removing the net horizontal section cutting bed by rotation.Wherein, the skewed slot helical ring that distributes on the spiral remover is owing to adopting the configuration design of importing and exporting different scale, show that flowing out the rear annular space drilling fluid flow velocity that flows in the other direction from drill bit increases rapidly, the drilling fluid flow velocity of increase can produce strong flushing action to the landwaste around the spiral remover.And the half elliptic spiral winding that arranges on the spiral remover has stronger heavily guide effect to the drilling fluid that passes through, and increases simultaneously the flow velocity by fluid.Like this, the change of flow direction and the increase of speed certainly will increase the spiral remover turbulence level of drilling fluid on every side, remove very favourable to cutting bed.In addition, the bar shaped accelerated band of the some that distributes on the local accelerator can excavate cutting bed in rotary course, stirs simultaneously two drilling fluids between the adjacent spiral remover, effectively prevents the landwaste sedimentation.
As seen, the utility model is by the combination configuration of net horizontal section cutting bed cleanout tool, change cutting bed cleanout tool on every side turbulent velocity and the intensity in drilling fluid flow field, make cutting bed destroyed under the cleanout tool of rotation drives, and the landwaste after will destroying carries out net horizontal section, on return to well head, effectively accelerate the drilling well process, reduce drilling cost.
