Abstract
The utility model relates to a hydraulic clog relieving device for drilling, which is mainly composed of an internal cylinder, a middle cylinder, an external cylinder, a starting device, an upper connecting loop and a lower connecting loop, wherein the starting device is installed in the internal cylinder, and discharge holes are formed on the pipe wall of the internal cylinder; discharge holes are also formed on the pipe wall of the starting device, and a spring is installed at the lower part of the starting device. When a drill is clamped, the starting device is pressed down, the discharge holes of the staring device coincide with the discharge holes of the internal cylinder, and drilling liquid flows into a cavity between the external cylinder and the middle cylinder through the discharge holes from interior of the starting device. Screw blades are installed on the external wall of the middle cylinder, and the drilling liquid flows to drive the screw blades to rotate at a high speed. The external cylinder is an eccentric cavity cylinder and can generate radial centrifugal force and high-frequency vibration when rotates to implement clog relief. The clog relieving device changes the traditional mode that drilling tools are forced to be struck out by using the vibration force generated by axial vibration, and utilizes the hydraulic action of well drilling liquid to generate high-frequency vibration and radial centrifugal force. The utility model has the advantages of high clog relieving efficiency and reliable performance.
Description
Technical field
The utility model relates to a kind of oil drilling releasing tool, and the fluid power that relates in particular to a kind of petroleum drilling operation is with boring release device.
Background technology
In the oil exploitation process, owing to stratum or operation reason, the situation that down-hole equipment is blocked appears sometimes.What generally use at present is axially vertical drilling jar, by on put forward or transfer the external force that drilling tool produces, bumper jar releases energy and produces axial blows power, reaches the purpose of unfreezing.But this method can only produce axial force, but needs the just unfreezing of greater impact power.When more serious jam occurring, jig is difficult to hit by force, and the unfreezing effect is relatively poor.
Summary of the invention
The utility model provides a kind of fluid power with boring release device, change traditional axial blows of leaning on and produced the mode that jarring force hits drilling tool by force, utilize the fluid power effect of drilling fluid that helical blade is rotated, the urceolus that drives release device rotates at a high speed, produce dither and radial centrifugal force, make by gap between position, card division drilling tool and the stratum constantly to increase, reach the purpose of unfreezing, unfreezing efficient height, dependable performance.
The technical scheme in the invention for solving the technical problem is: fluid power mainly is made up of inner core, middle tube, urceolus, starting drive, last connecting ring, following connecting ring with boring release device.Wherein inner core inside is cavity, and upper cavity is installed starting drive, and discharge orifice is arranged on the tube wall, and the tube wall outside is equipped with support ring, and bearing is placed on support ring top.Starting drive inside is cavity also, and places sealing ring between the inner core, and discharge orifice is arranged on the barrel, spring is equipped with in the bottom, when spring was depressed, the discharge orifice of starting drive overlapped with the discharge orifice of inner core, bore liquid can from starting drive inside through discharge orifice flow into urceolus and in the cavity between the tube.On the middle drum outer wall helical blade is installed.Urceolus is eccentric cavity tube, on one side wall thickness, wall is thin on one side, can produce centrifugal force during rotation.Middle tube and urceolus bottom are equipped with down connecting ring, tube and urceolus in the connection, and connected mode can be to weld, rivet, be threaded.In the following connecting ring discharge orifice is arranged.Inside and outside tube connects by last connecting ring.Last connecting ring is with the connected mode of inside and outside tube and is threaded.
The course of work of the present utility model is: when the situation that bit freezing occurs, following pressure startup device, make length of spring compressed, the discharge orifice of starting drive overlaps with the discharge orifice of inner core, bore liquid from starting drive inside through discharge orifice flow into urceolus with tin between cavity in, the helical blade that bores the mobile drive urceolus of liquid rotates at a high speed, because following connecting ring is welded on the urceolus, urceolus rotates thereupon, because of urceolus is eccentric tube, rotation produces dither and radial centrifugal force at a high speed, makes by gap between bit freezing tool and the stratum to increase gradually, realizes unfreezing.
When the bit freezing situation does not take place, do not need the started by press device, spring rises to the normal position, the discharge orifice of starting drive and the discharge orifice of inner core do not overlap, boring liquid can't be by in the inner cavity that flows between urceolus and the middle tube of starting drive, and helical blade does not rotate, and release device is not worked.
The utlity model has following superior effect:
1,, make by position, card division drilling tool easier to be loosening, higher than the method efficient that imposes axial force, and not fragile drilling tool by radial centrifugal force and dither.
2, through after the vibration, drilling tool and stratum produce the gap, can set up circulation, realize unfreezing quickly and easily.
3, urceolus and middle tube, inner core disalignment can according to different needs, be regulated the size that produces centrifugal force by regulating the axle offset distance of inside and outside tube.

The specific embodiment
Now introduce fluid power described in the utility model with boring the release device architectural feature and the specific embodiment in conjunction with Figure of description.
As shown in Figure 1 and Figure 2, fluid power described in the utility model is with the be threaded upper end of urceolus 2 and inner core 3 of the last connecting ring 1 that bores release device.Place packing ring 12 between last connecting ring 1 and the urceolus 2.Following connecting ring 7 is welded on the outer wall of the inwall of urceolus 2 and middle tube 5.There is following connecting ring discharge orifice 6 following connecting ring 7 inside.Urceolus 2 is eccentric cavity tube.Middle tube 5 is the cavity tube, and helical blade 4 is installed on its outer wall.Inner core 3 has discharge orifice 11 on the barrel in middle tube 5 cavitys, the riveted joint of outer wall top has support ring 8, places bearing 9 on the support ring 8.Inner core 3 is the cavity tube, the inner starting drive 13 of placing.The barrel of starting drive 13 has discharge orifice 10, and places two sealing rings 15 between the inner core 3, and spring 14 is placed in the bottom, is the cavity tube.
Above-mentioned discharge orifice (6,10,11) can be four, six, and when starting drive 13 was depressed, the discharge orifice 10 of starting drive and the discharge orifice of inner core 11 overlapped.
When the situation that bit freezing occurs, following pressure startup device 13, the discharge orifice 10 of starting drive is overlapped with the discharge orifice 11 of inner core, boring the liquid (not shown) flows into urceolus 2 cavitys from starting drive 13 inside through discharge orifice 10, bore helical blade 4 rotation at a high speed of the mobile drive urceolus of liquid, because down connecting ring 7 is welded on the urceolus 2, urceolus 2 rotates thereupon, because of urceolus 2 is eccentric tube, rotation produces dither and radial centrifugal force at a high speed, make by gap between bit freezing tool (not shown) and the stratum (not shown) to increase gradually, realize unfreezing.
The utility model is not limited to the foregoing description, and for the professional in present technique field, any improvement that the embodiment of the invention is made or change can not exceed the protection domain of design of the present invention and claims.
