The center tube (11) is provided with a screw thread which is connected with the union joint (1); the two ends of the body (3) are provided with the bearing (2) and the seal (10); the rotor of the dynamotor (4) is arranged on the body (3), and the stator of the dynamotor (4) is arranged on the center tube (11); a flute is arranged at the outer surface of the body (3), and the measuring control instrument (6) is fixed in the flute; the upper and the lower ends of the guard board (5) are provided with bolts which are fixed on the body (3); a hole at the slightly upper end position of the body (3) is provided with the plunger piston (7) inside, and the plunger piston (7) is provided with the spring (8) inside; the electromagnet (9) is fixed on the body (3) by the bolts.
Description
Technical field
The utility model relates to the downhole tool that oil drilling is used, particularly a kind of vertical drilling tool.
Background technology
Be that well deflection often takes place in Process of Oil Well Drilling, its harmfulness is very big, and the lighter influences bit speed, increases cost; Weight person scraps well, causes enormous economic loss.
Summary of the invention
At the above-mentioned on-the-spot practical problem that exists, the purpose of this utility model is to provide a kind of vertical drilling tool that can control hole deviation.
For achieving the above object, the technical solution adopted in the utility model is: mainly be made up of joint 1, bearing 2, body 3, generator 4, backplate 5, measurement and control instrument 6, plunger 7, spring 8, electromagnet 9, sealing 10 and central tube 11; Central tube 11 lower ends have screw thread to be connected with joint 1; Bearing 2 and sealing 10 are installed in the space between the two ends of body 3 and the central tube 3; The rotor of generator 4 is contained on the body 3, and its stator is contained on the central tube 11, and generator 4 is given measurement and control instrument 6 and electromagnet 9 power supplies; Between central tube 11 and body 3, be full of transformer oil; Body 3 external surfaces have a groove, and measurement and control instrument 6 is fixed in the groove; Backplate 5 upper and lower sides have screw to be fixed on the body 3, in order to protection measurement and control instrument 6, avoid mud to enter; Body 3 end position on the upper side has a through hole, and plunger 7 is housed in the hole, and spring 8 is housed in the plunger 7; Electromagnet 9 has screw on body 3.
Body 3 did not rotate when the utility model rotated at central tube 11, when measurement and control instrument 6 of the present utility model has measured well deflection, the adhesive of control electromagnet 9, thereby driving plunger 7 contacts with the borehole wall at the well flash, and produce a bit side force (elastic force of spring 8) that points to low limit, thereby play the effect of drop angle at the well flash.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Specific embodiment
Below in conjunction with accompanying drawing the utility model is further described in detail.
The utility model mainly is made up of joint 1, bearing 2, body 3, generator 4, backplate 5, measurement and control instrument 6, plunger 7, spring 8, electromagnet 9, sealing 10 and central tube 11; Central tube 11 lower ends have screw thread to be connected with joint 1; Bearing 2 and sealing 10 are installed in the space between the two ends of body 3 and the central tube 3; The rotor of generator 4 is contained on the body 3, and its stator is contained on the central tube 11, and generator 4 is given measurement and control instrument 6 and electromagnet 9 power supplies; Between central tube 11 and body 3, be full of transformer oil; Body 3 external surfaces have a groove, and measurement and control instrument 6 is fixed in the groove; Backplate 5 upper and lower sides have screw to be fixed on the body 3, in order to protection measurement and control instrument 6, avoid mud to enter; Body 3 end position on the upper side has a through hole, and plunger 7 is housed in the hole, and spring 8 is housed in the plunger 7; Electromagnet 9 has screw on body 3.
The utility model operating principle is as follows: when central tube 11 rotates, drive generator 4 and give measurement and control instrument 6 and electromagnet 9 power supplies, when measurement and control instrument 6 measures plunger 7 not during the flash in hole deviation, the adhesive of control electromagnet 9, plunger 7 is contacted at the flash of well and with the borehole wall, thereby produce a bit side force (being the elastic force of spring 8) that points to low limit at the well flash, thereby play the effect of drop angle.
