Description
The utility model is applied in the drillng operation in oil, geological drilling technology field.When drillng operation, in order to prevent well deflection, improve drilling quality, way is on drilling rod and drill collar usually, every a segment distance drilling tool stabilizer is installed.Stabilizer can play and keep the center of drill bit, drill collar, drilling rod consistent with the well center.Drilling tool stabilizer be meet the eye on every side, the essential instrument in pendulum and the increasing hole angle dropping assembly.The application is exactly a kind of drilling tool stabilizer.Also there is the people that drilling tool stabilizer is called the drilling tool centralizer.
At present, the drilling tool stabilizer of situ of drilling well use is broadly divided into two big classes.One class is the monolithic drilling tool stabilizer, and this class stabilizer makes with the most use at the scene.Another kind of is the roller drilling tool stabilizer.Each parts of existing drilling tool stabilizer all have rotation simultaneously with drilling tool.
The monolithic drilling tool stabilizer is on the body of drilling tool pipe nipple, is fixed with the straight line or the helical form wiper block that exceed body.The external surface welding-on of wiper block has hard materials such as carbide alloy or diamond.The external diameter of monolithic drilling tool stabilizer and borehole wall diameter basically identical.The disadvantage of monolithic drilling tool stabilizer is, wiper block rotates simultaneously with drilling tool, and the strip wiper block of stabilizer can rub, the scraping borehole wall, increases the drilling tool moment of torsion, reduces rig effective power, and enlarges hole diameter, destroys the borehole wall.
Someone decides the sliding friction of the wiper block and the borehole wall of device in order to overcome the monolithic drilling tool, and the shortcoming of the scraping borehole wall has designed the roller drilling tool stabilizer.The roller stabilizer is that three or six wheels that can roll that are exposed to the outside are housed on the body of drilling tool pipe nipple, and roller shaft is installed on the body of drilling tool pipe nipple.When drilling tool rotated, roller prolonged the borehole axis rotation on the drilling tool body, and roller also will carry out rotation, and the roller and the borehole wall produce rolling friction, and be littler than monolithic stabilizer with the frictional resistance of the borehole wall.The roller stabilizer can play the effect of stablizing drilling tool, has also reduced the frictional resistance with the borehole wall simultaneously.But roller rolls friction is arranged still on the borehole wall, also can cause hole diameter to enlarge.In addition, roller is exposed to the outside, and when the put-on and delegated drilling tool, the easy scraping borehole wall of roller can break roller sometimes.Because roller is exposed to the outside, the rock that falls down from the borehole wall, foreign material etc. can be stuck in the middle of roller and the body, make roller stuck, can not rotate, and have lost rolling action.Carry out the dark oil gas well drilling of the thousands of rice of a bite, need to use simultaneously tens drilling tool stabilizers sometimes.Drilling tool stabilizer is many more, with the frictional resistance of the borehole wall can be big more.Not only consumed rig power, increased drilling cost and also destroy the borehole wall, increased many difficulties to drillng operation.
The purpose of this utility model is that the roller that overcomes the roller drilling tool stabilizer is exposed to outside shortcoming; The roller that overcomes the roller stabilizer contacts with the borehole wall and rotates simultaneously with drilling tool, the roller friction borehole wall during drilling tool rotation, the shortcoming that causes hole diameter to enlarge; And prevent to fall into, the accident of stuck roller takes place from the rubble that the borehole wall falls.
The technical solution of the utility model is: be provided with supporting positive cover in drilling tool pipe nipple body exterior, the supporting positive cover maximum outside diameter and the borehole wall adapt.Supporting positive cover can support the borehole wall, and the drilling mud passage is arranged on the supporting positive cover.Drilling tool pipe nipple body rotates simultaneously with drilling tool in the drilling process, and supporting positive cover does not rotate.Roller wheel bearing seat and roller are arranged in supporting positive cover.The outside of roller wheel bearing seat is a supporting positive cover.The axle at roller two ends is installed on the supporting base, and the quantity of roller is 3-12, and roller is near drilling tool pipe nipple body.The supporting base two ends are provided with joint ring, make that the mud in the pit shaft can not enter supporting base, protection roller and roller shaft.There is plane bearing outside at joint ring, and with locking cap two ends is fixed.Sealing ring is arranged on the locking cap, make mud can not enter plane bearing.
In order to make drilling tool stabilizer be convenient to make and use, the length of roller wheel bearing seat can design between 200～1000 millimeters.The thickness of supporting positive cover is between 3～30 millimeters.Preferably 6 of the quantity of roller wheel bearing seat.The connecting mode of roller and supporting base can adopt axle sleeve to connect.For the lubricated resistance that reduces, lubriation material can be adorned in supporting positive cover inside.
The application's great advantage is, when drilling tool rotated at a high speed, a part of part of drilling tool stabilizer rotated with drilling tool, and supporting positive cover is close to the borehole wall, and with the drilling tool rotation, supporting base does not rotate with drilling tool yet.Drilling tool stabilizer can not destroy the borehole wall like this, play good set upright, stabilization.In drilling tool stabilizer interior roller and the rolling friction of drilling tool pipe nipple body, rotation is carried out in the roller original place.Use joint ring in addition, prevent that drilling mud from entering supporting base inside, protection internal lubrication material.Sealing ring is arranged, prevent that drilling mud from entering in the plane bearing.The upper-lower position of nut pressure cap energy fixed muffle, supporting base, roller.
