Description
Technical field
The present invention relates to petroleum well logging technology field, particularly relate to a kind of pitching and shear release.
Background technology
Currently for pumping out memory-type instrument, instrument release pumps out to use and produces mud by well head turn on pump, pass pump
Pressure height low pulse signal controls.Instrument internal pressure probe receives effective high-low pressure signal within a certain period of time and enters
Row is analyzed and is judged, is regained by motor and hang over the pin on hanger when signal is effective, and then release instrument.Owing to surveying in reality
In well task, each drilling team equipment is different, is difficult to get good high-low pressure signal at the appointed time, on the other hand,
Along with the increase of well depth, the remaining more time delay of pressure transmission, often well head has beaten signal, and shaft bottom instrument receives invalidating signal, leads
Cause instrument release failure.
Summary of the invention
The purpose of the present invention is aiming at above-mentioned problem of the prior art, it is provided that release is sheared in a kind of pitching, solves
The problem that prior art instrument release failure rate is high.
The purpose of the present invention is realized by following technical proposals:
Release is sheared in a kind of pitching, hangs six pawl joint and stop collars including shear sleeve, instrument, and described shear sleeve is socketed in limit
Outside the set of position, the top of shear sleeve is provided with ball seat, and is configured with the shear balls mated with ball seat, and shear pin is passed through on the top of stop collar
Nail is connected with shear sleeve, and tail end inserting instrument hangs in the pawl head of six pawl joints, and the pawl head that instrument hangs six pawl joints is limited
Between shear sleeve inwall and stop collar outer wall, it is instrument union joint that instrument hangs the other end of six pawl joints, works as shear pin
After cutting off, instrument hangs six pawl joints and removes shear sleeve with under stop collar.
Further, there is the slurry channel communicated with ball seat in whole shearing release, and hang on six pawl joints at instrument
Offer the circulating opening being communicated to outside.
Further, described shear sleeve inwall is provided with limited step, and stop collar outer wall is to there being annular groove, when instrument hangs
When the pawl head of six pawl joints is limited between shear sleeve inwall and stop collar outer wall, pawl head is that limited set outer wall is spacing in limit
On the step of position, annular groove is positioned at pawl head top, and instrument hangs the inwall correspondence stop collar bottom of six pawl joints and is provided with boosting
Step.
Compared with prior art, the beneficial effects of the present invention is: simple in construction, reasonable in design, convenient and practical, not pipe well
Team, equipment, well depth situation, under mud pushes, steel ball can arrive ball seat surely, will shear disconnected pin and then release after setting ball seat
Put and pump out instrument.Greatly improve instrument release and pump out success rate.
Accompanying drawing explanation
Fig. 1 is the integral installation distribution structure schematic diagram of the present invention;
Fig. 2 is the structural representation of shear sleeve in Fig. 1;
Fig. 3 is the structural representation of stop collar in Fig. 1;
Fig. 4 is the structural representation that Fig. 1 Instrumental hangs six pawl joints.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
As shown in Figures 1 to 4, release is sheared in a kind of pitching, hangs six pawl joints 2 and spacing including shear sleeve 1, instrument
Set 3, described shear sleeve 1 is socketed in outside stop collar 3, and the top of shear sleeve 1 is provided with ball seat 4, and is configured with and cutting that ball seat 4 mates
Cut 5, the top of stop collar 3 is connected with shear sleeve 1 by shear pin 6, and tail end inserting instrument hangs the pawl head of six pawl joints 2
In, instrument hangs the pawl head of six pawl joints 2 and is limited between shear sleeve 1 inwall and stop collar 3 outer wall, and instrument hangs six pawls and connects
The other end of 2 is instrument union joint 7, and after shear pin 6 is cut off, instrument hangs six pawl joints 2 and removes with stop collar 3 one
Removal shear sleeve 1.
Offer the axis hole 101 communicated with ball seat 4 on described shear sleeve 1, and the changeover portion of ball seat 4 and axis hole 101 is downward
Reducing 102.Stop collar 3 offers axially extending bore 301, and its top is outside horn mouth 302.On shear sleeve 1 and stop collar 3 right
Pin-and-hole should be offered, this pin-and-hole is installed shear pin 6 both are linked together.Instrument hangs six pawl joints 2 at the one of pawl head
End offers axial blind hole 201, offers the circulating opening 202 being communicated to outside bottom blind hole 201.When instrument hangs six pawl joints
2, after stop collar 3 and shear sleeve 1 are assembled into pitching shearing release, the slurry channel communicated with ball seat 4 in it, is formed, and at mud
Slurry channel bottom has the circulating opening 202 being communicated to outside.
The shaft hole inner wall of described shear sleeve 1 is provided with limited step 103, stop collar 3 outer wall to there being annular groove 303, when
Instrument hangs the pawl head of six pawl joints 2 when being limited between shear sleeve 1 inwall and stop collar 3 outer wall, and pawl head is limited set 3
Outer wall is spacing on limited step 103, and annular groove 303 is positioned at pawl head top, and instrument hangs the blind hole 201 of six pawl joints 2
Inwall correspondence stop collar 3 bottom is provided with boosting step 203.
In well logging, instrument hangs six pawl joints 2 and connects instrument by instrument union joint 7, under get into the purpose degree of depth,
Put into that shear balls 5(the present embodiment of suitable outer diameter uses for steel ball), steel ball is through ball seat 4, steel ball quilt under mud pushes
Being stuck at the horn mouth 302 on stop collar 3 top, steel ball has sealed mud down going channel, and it is downward that stop collar 3 therefore suffers from steel ball
Pressure, stop collar 3 pressure is gradually increased, when active force is more than being arranged on the shear pressure of shear pin 6 on shear sleeve 1
After, steel ball cuts off shear pin 6 under mud propelling movement effect, and then promotes stop collar 3 to move down so that instrument hangs six pawl joints
The pawl head of 2 is between stop collar 3 annular groove 303 and shear sleeve 1 inwall, stop collar 3 bottom contact boosting step 203, from
And drive instrument to hang six pawl joints 2 and move out shear sleeve 1 downwardly together with stop collar 3 so that instrument separates reality with shear sleeve 1
Existing instrument release pumps out.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Any amendment, equivalent and the improvement etc. made within god and principle, should be included within the scope of the present invention.
