Brief description of the drawings
Fig. 1 is that jarring described in the utility model prevents that moving up instrument pulls open view.
Fig. 2, which is that jarring described in the utility model is anti-, moves up tool closed condition schematic diagram.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
As shown in figure 1, jarring provided by the utility model is anti-to move up instrument, including：Cylinder 107, jar stem 104, support
Pawl 110 and lower union joint 114.
Jar stem 104, its one end have boss 106, and one end that jar stem 104 has boss is arranged in cylinder 107, is shaken
One end that the other end of bar 104 stretches out cylinder 107 is hit, jar stem 104 can slide along the inwall of cylinder 107；Pressure cap 105 is arranged on cylinder
The both ends of body 107, to prevent jar stem 104 from being skidded off in vivo out of cylinder 107；Two support claws 110, it is fixed by pin 109 and set
Put on cylinder 107, spring 108 is provided between two support claws 110；Lower union joint 114, its one end have tapered cap 112,
One end that lower union joint 114 has tapered cap 112 is arranged in cylinder 107, and the other end of lower union joint 114 stretches out cylinder 107
The other end, and can be slided along the bearing of trend of lower union joint 114.
As shown in figure 1, tool tip is upper junction button 101, bottom is lower junction button 115, and both sizes, button-type are
The steel wire downhole tool of standard is buckled, and can be that screw thread is alternatively breechblock button.Upper junction button 101 is below fishing neck 102, is standard steel
Silk operation downhole tool fishing neck.
Functionally, whole instrument can be divided into two parts, and top half has up jarring function, mainly by living
What the jar stem 104 of stick harness structure was realized, jar stem 104 and fishing neck 102 are by screwed connection, to ensure that screw thread is not threaded off,
Interior hexagonal flush end holding screw 103 is provided with screwed connection, jar stem 104 can be freely up and down in the inside of cylinder 107, shake
Hit the external diameter of bar lower end boss 106 and be more than the internal diameter of pressure cap 105, and both contact faces are plane, pressure cap 105 is connected with cylinder 107
Integrally, pressure cap 105 limits the operating range of jar stem 104.
As shown in Figure 2.For closure state, if fixed cylinder 107, upper junction button 101 quickly up moves a segment distance, arrives
Up to state is pulled open shown in Fig. 1, the upper drive of junction button 101 jar stem 104 produces jarring force up to pressure cap 105, and will up
Power be transferred to the latter half of instrument.
The latter half has the anti-function of moving up, and principle is that cone cap 112 is that (top is flat to a conical tip
Face), it is connected by screw thread with lower union joint 114, to ensure not thread off, elastic cylindrical pin 113 is provided with screw thread, when cone cap
112 when up being moved, and support claw 110 can be promoted to be opened to instrument outer end, when boring cap 112 and running to top, support claw 110
Opening completely (see Fig. 2 closure states), support blade tooth 111 is stuck on tube inner wall, and the tooth of support blade tooth 111 is reverse tooth, when
Support blade tooth is when being stuck in tube inner wall, and it is tighter that impact from lower to upper make it that tooth can block.Meanwhile in normal state, support
After pawl 110 is opened, as long as cone cap 112 is descending, support claw 110 is no longer promoted, one is provided at upper junction button 101 toward pull-up
Power, support claw 110 can voluntarily be returned in the presence of spring 108 in tool body, return to Fig. 1 and pull open state.When from it is lower toward
On impulsive force it is larger so that support blade tooth 111 block it is very dead when, it is now quick on put on junction button 101, pass through jar stem
104 up jarring pressure caps 105, can also cause support claw to withdraw.
Two support claws 110 are fixed with cylinder 107 using pin 109.
The bottom external diameter for boring cap 112 is more than the internal diameter of pressure cap 105, and both contact surfaces are plane, and pressure cap 105 limits cone
Cap 112 and the operating range of lower contact 114.
Implement so that jarring is prevented moving up the course of work of instrument as an example, be described further
When preventing that moving up instrument carries out out sliding sleeve operation using jarring, the anti-instrument upper end that moves up of jarring is rope socket, and lower end connects
Connect the tool strings such as weighted lever, bumper jar and sliding sleeve shifting tool, it is normal on put when putting tool string, jarring is anti-to be moved up instrument and is in
State is pulled open, when opening sliding sleeve moment, strata pressure is much larger than well cylinder pressure, and the pressure differential meeting percussion tool string of moment is quick
Up moving, tool string band mantle cap 112 quickly up moves, and so as to promote support claw 110 to open, is stuck on tube inner wall,
Prevent the quick of tool string from up moving, avoid steel wire fracture.Impact terminate after, tool string because Action of Gravity Field down moves,
Band mantle cap 112 is moved down, and now support claw 110 is still stuck on tube inner wall, carries the weight of following tool string, now on
Steel wire is carried, support claw 110 is withdrawn, and comes back to the state of pulling open.If support claw 110 can not normally be withdrawn, decentralization one section away from
From steel wire, then quickly above carry, jar stem 104 above carries jarring pressure cap with the quick of steel wire, after operating repeatedly, you can will support
Pawl 110 is withdrawn.
Bumper jar is moved up instrument perfect adaptation by the present apparatus with anti-, forms an instrument, has the anti-work(moved up with jarring concurrently
Can, good effect is achieved in actual use, greatly reduces out the risk of sliding sleeve operation.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to various suitable fields of the present utility model completely, for those skilled in the art,
Other modification is easily achieved, therefore under the universal limited without departing substantially from claim and equivalency range, this reality
Specific details is not limited to new and shown here as the legend with description.
