A plurality of centering belts (3) are arranged on the circumferential face of the centering shaft (4), a mounting hole is formed in the circumferential face of the mounting shaft (5), and a senor probe (6) is fixedly connected inside the mounting hole. A through hole which penetrates through the main body in the axial direction is also formed in the main body, and an internal thread is arranged in the portion, in the internal joint shaft (1), of the through hole. The drilling-tool stabilizer with the sensing device can be used for monitoring a drilling tool in the whole using process of the drilling tool, the number of well deviation phenomena can be reduced, and the service life of the drilling-tool stabilizer with the sensing device is long.
Description
Technical field
The utility model relates to a kind of oil-well drilling equipment, specifically is a kind of drilling tool stabilizer with sensing device.
Background technology
The drilling well stabilizer is the main tool for oil drilling engineering control hole deviation.The drilling well stabilizer when drilling well owing to will control and reduce rate of azimuth change and the hole deviation rate of drilling tool, improve wellbore quality and bit speed, the minimizing accident takes place, reduce drilling cost, so need to measure drilling tool accurately, timely in travel path and the environmental change in shaft bottom, change and the hole deviation situation to analyze the orientation, for reaching accurate measurement, we have designed a kind of drilling tool stabilizer that has sensor, thereby analyze, judge that by the measurement to environment in the well drilling tool changes in the well, adjust wrong conduct timely, improve drilling quality.
The utility model content
The utility model provides a kind of drilling tool stabilizer with sensing device, and be used for solving in the past drilling tool is prone to problems such as hole deviation, orientation variation when drilling well, can realize the shaft bottom complete monitoring to drilling tool.
The technical scheme that the utility model provides is: the drilling tool stabilizer of band sensing device, the main body that comprises a shape, described main body includes the spigot axle successively, sets upright axle, installation shaft and cone joint totally four parts, a described periphery of setting upright is provided with several and sets upright band, described installation shaft periphery has installing hole, be connected with sensor probe in the installing hole, described body interior also is provided with the through hole that axially runs through main body, and described through hole is provided with internal thread at the position of spigot axle.Drilling tool stabilizer is set upright band and is contacted with the borehole wall and to reach guide effect when drilling well, can adjust the orientation of drilling tool.Sensor probe can be deep-well pressure sensor probe, also can be the water level of deep well sensor probe, it can also be the two combination, can select to use according to the drilling well concrete condition, sensor cable adopts water-proof cable, be connected with the external sensor receiving terminal by the main body inner via hole, can carry out complete monitoring to stabilizer, avoid occurring the variation of drilling tool orientation and drilling well and the hole deviation phenomenon occurs.
Described spigot axle also is provided with positioning screw hole perpendicular to the spigot axle at periphery.Dog screw with spigot axle and stabilizer connector axial restraint, is prevented the anti-avulsion bar by positioning screw hole.
Described installation shaft periphery also is provided with rises as high as the banks.The drilling tool stabilizer main body is a shape; the staff is difficult for exerting all one's strength when assembling; need the employing instrument to finish connection; clamping place when rising as high as the banks for staff's place tool; avoid instrument to skid in use, also can avoid tool damage main body periphery, not only protected body surfaces; make things convenient for staff's loading and unloading, also reduced staff's workload.
Described rising as high as the banks is provided with two altogether, is circularly and evenly distributed in installation shaft each other.Instrument can symmetrical clamping main body when clamping, stress balance, and the workload that can reduce a staff, and can prevent that instrument from skidding in body surfaces.
The length of described cone joint is not less than 10 centimetres.Cone joint needs to bear bigger connection active force after connecting, if cone joint was prone to fracture after connecting when cone joint was too short, thereby cause damage and accident, so the length of cone joint is not less than 10 centimetres of intensity that can guarantee the cone joint junction.
The described band matter of setting upright adopts the WC carbide alloy.A kind of alloy material that the WC carbide alloy is made by powder metallurgical technique by hard compounds and the binding metal of refractory metal is common current material.The WC carbide alloy has a series of premium properties, particularly its high rigidity and abrasion resistance such as hardness height, wear-resisting, intensity and toughness is better, heat-resisting, corrosion-resistant, even also remain unchanged substantially under 500 ℃ temperature, still has very high hardness in the time of 1000 ℃.There is friction owing to set upright band with the borehole wall, adopt the WC Hardmetal materials can not only satisfy the job requirement of down-hole so set upright band, and its abrasion resistance is extremely strong, has prolonged the application life of setting upright band greatly.
Advantage of the present utility model is: the drilling tool stabilizer of this band sensing device of the utility model design, can carry out complete monitoring to drilling tool, and reduce the hole deviation phenomenon, and long service life.
