Abstract
The utility model discloses a kind of stabilizer with reaming while drilling ability, comprise into the stabilizer body and the strip wing that are integrated, it is characterized in that: on the periphery of fin, be furnished with columned gauge block, two ends on the right side of fin are provided with fillet surface, and this fillet surface is provided with gauge teeth.Because gauge teeth has shear action to rock of borehole, well can be expanded, therefore enable in stabilizer drilling process of the present utility model, can solve because of well reduced diameter, and cause the rough sledding such as backing pressure, bit bouncing, torque ripple or bit freezing, thus improve drilling efficiency, reduce drilling cost.
Description
Technical field
The utility model belongs to drilling tool technical field, specifically relates to a kind of in the stabilizer with reaming while drilling ability.
Background technology
Stabilizer is the particle size joint with fin (vertical bar or spirality).In drilling process, when drill string turns round at a high speed in well, the radial and axial high vibration of drill string elastic system in hole is alleviated by stabilizer, keep elongate drill rod smooth operation, drill axis is rotated close to drill center line as far as possible, has simultaneously and reduce drill bit and drilling rod eccentric wear, inclining prevention.
Existing stabilizer generally contacts with the borehole wall with flap apex arcwall face, reaches righting drilling tool and gauge effect.In drilling process, the gauge ability of stabilizer much larger than bit gauge protection ability, as drill bit because external diameter wearing and tearing and cause institute's drilling well eye outside dimension to be less than stabilizer outside dimension, easy generation backing pressure, even occur situation about cannot creep into, need pull out of hole more bit change, increases drilling cost.Moreover as bore meet easy undergauge stratum or mud property not up to standard, cause borehole wall reduced diameter, easily cause the situations such as bit freezing, bit bouncing, torque ripple, even cause serious drilling failure, bring tremendous economic to lose to construction party.
Utility model content
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art part exactly, the stabilizer with reaming while drilling ability is proposed, can solve and cause the rough sledding such as backing pressure, bit bouncing, torque ripple or bit freezing because of well reduced diameter, thus improve drilling efficiency, reduce drilling cost.
In order to solve the problem, a kind of stabilizer with reaming while drilling ability of the utility model, comprise into the stabilizer body and the strip wing that are integrated, it is characterized in that: on the periphery of fin, be furnished with columned gauge block, two ends on the right side of fin are provided with fillet surface, and this fillet surface is provided with gauge teeth.
Described gauge block can only the grinding borehole wall, makes the borehole wall more smooth, can not expand borehole size, and the gauge teeth arranged on fin fillet surface, shear action can be played to rock of borehole, therefore, it is possible to expand borehole size.
In technique scheme, the exposure of described gauge block is in the periphery of fin, and proud exposure is 0.5-2mm.The exposure of described gauge block, in the outer round surface of fin, can slow down the wearing and tearing of rock of borehole to fin effectively.
The angle α of the fillet surface on the right side of described fin and fin right flank is 30 °-60 °, and the width d of fillet surface is 10-20mm.
The angle β of described gauge teeth end face and fin right flank is 30 °-45 °.
The material of described gauge block is carbide alloy, and the material of described gauge teeth is diamond compact.
In sum, the utility model is a kind of has the stabilizer of reaming while drilling ability compared with stabilizer of the prior art, the device fin fillet surface of stabilizer is provided with gauge teeth, shear action is played to rock of borehole, therefore, it is possible to solve because of well reduced diameter, and cause the rough sledding such as backing pressure, bit bouncing, torque ripple or bit freezing, thus improve drilling efficiency, reduce drilling cost.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
What Fig. 1 and Fig. 2 illustrated indicates a kind of basic structure with the stabilizer of reaming while drilling ability of the utility model, it comprises into the stabilizer body 1 and strip fin 2 that are integrated, it is characterized in that: on the periphery 3 of fin 2, be furnished with columned gauge block 5, two ends on the right side of fin 2 are provided with fillet surface 4, and this fillet surface 4 is provided with gauge teeth 6.Stabilizer as shown in Figure 2 has 4 fins 2, in the stabilizer structure figure shown in Fig. 1, the periphery 3 of each fin 2 has been covered with gauge block 5, has had 4 rows, totally 48.In order to be that gauge block 5 can protect fin 2 not worn and torn by rock of borehole, the exposure of described gauge block 5 in the height of the periphery 3 of fin 2 be 0.5-2mm.
Described gauge block 3 of stating can the grinding borehole wall, maintains borehole size, makes the borehole wall more smooth, but can not expand borehole size.Therefore on the fillet surface 4 on the right side of stabilizer fin 2, gauge teeth 6 is provided with.As shown in Figure 1, two gauge teeths 6 are respectively provided with at the two ends of fin 2.In order to make gauge teeth 6 can rock cutting effectively, expand borehole size, gauge teeth 6 will rock cutting at a certain angle, and as shown in Figure 3, the angle β of gauge teeth 6 end face and fin 2 right flank is 30 °-45 °.
Described gauge teeth 6 needs to be arranged on fillet surface 4, diameter stock size due to gauge teeth 6 is 10-20mm, according to the diameter of gauge teeth 6, as shown in Figure 4, described fillet surface 4 is 30 °-60 ° with the angle α of fin 2 right flank, and the width d of fillet surface 4 is 10-20mm.
The material of described gauge block 5 is carbide alloy, and the material of described gauge teeth 6 is diamond compact.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
