Abstract

The utility model relates to a cleaning tool of a directional well, a horizontal well or an extended reach well, in particular to a borehole cleaning tool. The tool is formed through one piece machining; screw threads are machined at two ends of a main body; a gauge centralizer, a cleaning belt, a slant edge centralizer and a V-shaped centralizer are sequentially designed on the main body from the right part to the left part; a spiral prismatic flow channel is machined on the gauge centralizer; a hard alloy block is embedded on the centralizing edge of the gauge centralizer; a groove is designed on the cleaning belt; a slant edge shaped flow channel is machined on the slant edge centralizer; a V-shaped spiral prismatic low channel is machined on the V-shaped centralizer; and a hard alloy block is embedded on the centralizing edge of the V-shaped centralizer. The cleaning tool reduces the probability of cuttings bed forming during the process of well drilling, and can effectively eliminate formed cuttings beds, so as to achieve the purpose of borehole cleaning. The cleaning tool overcomes the insufficiency that cuttings beds are easy to form at the existing highly-deviated intervals so as to cause the increasing of the torque of a drill stem during drilling.

Description

A kind of well burnisher
Technical field:
The utility model relates to a kind of directional well, horizontal well, extended reach well cleanout tool, particularly a kind of well burnisher.
Background technology:
At present, in the oil drilling field, the enforcement of exceptional well types such as directional well, horizontal well, extended reach well is more and more; And in the construction of these exceptional well types; Cutting grain is descended by the effect of gravity, is prone to form accumulation at the following borehole wall of high angle hole section, to a certain degree just having formed cutting bed; And the drilling tool gravitate is pressed close to the borehole wall down; The formation of cutting bed and the increase of thickness can cause making a trip obstructed, and the suffered moment of torsion of drill string increases when causing creeping into, and causes down-hole complex accident such as bit freezing when serious.
The utility model content:
The technical problem that the utility model will solve provides a kind of well burnisher, this tool implementation reduce the probability that in drilling process, forms cutting bed, and can effectively eliminate established cutting bed, reach the purpose of cleaning well.The deficiency that the drill string moment of torsion increases when having overcome existing high angle hole section and be prone to forming cutting bed and cause creeping into.
The technical scheme that the utility model is taked is: a kind of well burnisher comprises body; This instrument one machine-shaping, the body two ends all are processed with screw thread, are designed with successively from right to left on the body to protect footpath centralizer, cleaning band, slant edge centralizer, V-arrangement centralizer; Protect on the centralizer of footpath and be processed with spiral prismatic runner; Set upright and stud with hard alloy blocks on the rib, be designed with groove on the cleaning band, be processed with slant edge shape runner on the slant edge centralizer; Be processed with " V " type spiral prismatic runner on the V-arrangement centralizer, set upright and stud with hard alloy blocks on the rib.
The beneficial effect of the utility model is: the utility model is owing to adopted three groups of centralizers with special runner; Thereby reduced the probability that in drilling process, forms cutting bed, and can effectively eliminate established cutting bed, clean well; The finishing borehole wall; And then improve wellbore quality and rate of penetration, and reduce the drilling well risk, improve overall efficiency.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Accompanying drawing is the structural representation of the utility model.
The specific embodiment:
Shown in accompanying drawing, a kind of well burnisher comprises body 1; This instrument one machine-shaping, the centre does not have screwed connection, has ensured the intensity of instrument, and body 1 two ends all are processed with screw thread; Be designed with successively from right to left on the body 1 and protect footpath centralizer 2, cleaning band 3, slant edge centralizer 4, V-arrangement centralizer 5, protect on the centralizer 2 of footpath and be processed with spiral prismatic runner, set upright and stud with hard alloy blocks on the rib; Can repair forming the slim hole well section, play the effect that the footpath is protected in drifting, be designed with groove on the cleaning band 3; Can become flexible the cutting bed of the borehole wall down, make it, be processed with slant edge shape runner on the slant edge centralizer 4 with returning on the drilling fluid; Can when drill string rotating, form turbulence effect, destroy cutting bed, make suspension of cuttings in drilling fluid; Its special runner design can improve the drilling fluid migration rate moment, and then improves the migration effect to landwaste, is processed with " V " type spiral prismatic runner on the V-arrangement centralizer 5; Set upright and stud with hard alloy blocks on the rib, in the time of can guaranteeing to carry drilling tool the finishing borehole wall, processing " " the type runner can make drilling fluid bend to V; Form spiral flow, landwaste moment of carrying at the entering upper annulus, finally realize the removing of landwaste.
It is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.

Claims (1)
