Abstract
The invention relates to a rotary swing guiding drilling tool, which can solve the technical problem that a well is drilled obliquely on an easily oblique well section, particularly can increase/ reduce azimuths and well inclination as required in a directional well and can realize guiding drilling in horizontal well drilling. The rotary swing guiding drilling tool comprises a drilling tool main body; the main body is respectively matched and connected with an upper joint and a lower joint; the middle part of the main body is provided with a drainage hole; the outside surface of the main body is provided with a liquid inlet; the liquid inlet is communicated with a plunger hole for assembling a plunger; the plunger is cylindrical, and a sealing ring matched with the plunger is arranged on the external circle of the plunger; a centralizing sleeve is sleeved outside the main body and matched with a jaw on the external end face of the upper joint; hard alloy teeth are embedded into the centralizing sleeve; an electromagnetic switch is arranged at the lower end of the main body; and the electromagnetic switch is connected with the liquid inlet.
Description
One, technical field:
The present invention relates to a kind of guide drilling tool, especially relate to a kind of rotary oscillation guide drilling tool that can be convenient to be installed on the underground drill stem, it is applicable to deviation control with drilling straight well, drilling guidance in the petroleum geology drilling well.
Two, background technology:
Present domestic rotary steering drilling tool does not also occur, and rotary steerable drilling system is arranged abroad, and the mechanical support principle is that three-jaw or four paws support the borehole wall, is difficult in general aboveground use.
Three, summary of the invention:
The present invention is in order to solve the weak point in the above-mentioned background technology; A kind of rotary oscillation guide drilling tool is provided; It can overcome well at easy lower curved section and beat oblique technical barrier, particularly in directional well, can increase and decrease orientation and hole deviation as requested, in horizontal well drilling, can realize steerable drilling.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
A kind of rotary oscillation guide drilling tool is characterized in that: comprise the drilling tool main body, main body matches with lower contact with top connection respectively and is connected; The main body middle part is provided with outage, and the external side of main body face is provided with inlet opening, and inlet opening communicates with the plunger hole of assembling plunger; Main body is with supporting positive cover outward; Supporting positive cover and top connection outer face tooth scarf close, and electromagnetic switch is equipped with in the main body lower end, and electromagnetic switch links to each other with inlet opening.
Above-mentioned plunger is cylindrical, and the sealing ring that matches is arranged on the cylindrical.
Stud with hard-metal insert on the above-mentioned supporting positive cover.
The aforementioned body two ends are that special screw thread is used in drilling well, and main body is threaded with top connection and lower contact.
Compared with prior art, the advantage and the effect that have of the present invention is following:
1, the present invention can overcome well at easy lower curved section and beats oblique technical barrier; Particularly in directional well, can carry out according to technician's requirement; Increase and decrease orientation and hole deviation can realize steerable drilling in horizontal well drilling, for from now on automated drilling and closed loop drilling well provides downhole tool;
2, downhole tool of the present invention is mixed the automated drilling that down-hole and aboveground electronic instrument have just possessed simple form again.
Four, description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an outside drawing of the present invention.
Among the figure, 1-top connection, 2-main body, 3-supporting positive cover, 4-plunger, 5-sealing ring, 6-inlet opening, 7-lower contact, 8-electromagnetic switch, 9-outage, 10-hard-metal insert.
Five, the specific embodiment:
Referring to Fig. 1 and Fig. 2, rotary oscillation guide drilling tool of the present invention is made up of top connection 1, main body 2, lower contact 7, supporting positive cover 3, hard-metal insert 10, plunger 4, electromagnetic switch 8.Top connection 1 hollow is the drilling fluid passage; Two ends are that special screw thread is used in drilling well, top connection 1 one termination drill bits, broken formation; The end that top connection 1 other end outer face cooperates with supporting positive cover 3 closes for the tooth scarf; Top connection 1 inner face links to each other with main body 2, and main body 2 two ends are that special screw thread is used in drilling well, and binding matches with top connection 1 and lower contact 7.Communicate up and down for irregularly-shaped hole in the main body 2, be the drilling fluid passage, main body 2 middle parts have outage 9 to be used for drained liquid pressure.Inlet opening 6 passages are arranged on main body 2 lateral surfaces; Communicate with the plunger hole of assembling plunger 4, plunger 4 is cylindrical, and the sealing ring 5 that matches is arranged on the cylindrical; The main body 2 outer supporting positive covers 3 that are with; Supporting positive cover 3 closes with top connection 1 outer face tooth scarf, studs with hard-metal insert 10 on the supporting positive cover 3, is used to guarantee that the external diameter of supporting positive cover 3 remains unchanged.Electromagnetic switch 8 is equipped with in main body 2 lower ends, and electromagnetic switch 8 links to each other with inlet opening 6.Electromagnetic switch 8 is controlled stretching out of plungers 4 and is withdrawn.
During real work; Behind the instrument G.I.H; Pass through in the main body 2 from the drilling fluid that certain pressure is arranged of lower contact 7; Apparatus measures control circuit control electromagnetic switch 8 in the instrument, when the electromagnetic switch 8 on the right was opened, pressure fluid can get into the interior plunger 4 that promotes of plunger hole through inlet opening 6 and outwards promote supporting positive cover 3 motions.Simultaneously, the pressure in the plunger hole on the left side is drained through outage 9, plunger 4 reversion under the effect of supporting positive cover 3, and main body 2 is to left movement.When the electromagnetic switch 8 on the left side was opened, pressure fluid can get into the interior plunger 4 that promotes of plunger hole through inlet opening 6 and outwards promote supporting positive cover 3 motions.Simultaneously, the pressure in the plunger hole on the right is drained through outage 9, plunger 4 reversion under the effect of supporting positive cover 3, and main body 2 moves right.Along with the not stall of drill string is moving, the direction of motion of the switch control plunger 4 that electromagnetic switch 8 is not stopped, thus the direction of motion that reaches main body 2 is controlled, Controlling Borehole Trajectory.
