The utility model discloses be six prismatic to pull rod design, form six little sectors between pull rod and the section of thick bamboo wall, strengthened the szyrt passageway, simultaneously with the urceolus wall down the clearance hole of bottom change the inclined hole that the downward sloping set up into, inner bottom in the section of thick bamboo changes taper shape, be convenient for discharge sand and debris into, the utility model discloses the problem of bumper jar sand card has effectively been solved.
Description
Technical field
The utility model relates to Oil/gas Well Well Test Technology field, especially a kind of sands-proof check bumper jar.
Background technology
Steel wire launch-work operation often uses bumper jar, and mechanical rod-pulling type bumper jar application is the most general, and bumper jar pull bar before all adopts cylindrical, exists often by the drawback of sand card.Such as, in the operation of long celebrating Su Lige gas well pulling restriction choke, due to fracturing sand, row is unclean, or tell sand in well, once sand enters bumper jar urceolus during operation, between pull bar and barrel, cause jam with regard to easy, bumper jar can not close in down-hole, lose jarring action, downhole operations action cannot be completed, and not only restriction choke can drag for out, and kit string also cannot be slipped out of the hand, steel wire and tool string are thrown away entirely in well, cause complicated engineering accident.Gap between cylindrical rod and barrel is too little, and be unfavorable for the excretion of sand and other impurity, this is the major defect of legacy bumper jar.Because be limited by OIH pipe size and pull bar intensity and stability, strengthen outer barrel diameter or reduce pull bar diameter all infeasible.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of sands-proof check bumper jar that can solve bumper jar sand card problem.
In order to solve the problems of the technologies described above, the utility model comprises the pull bar pressure cap and urceolus that link together and to be arranged in pressure cap and urceolus and the pull bar that can slide up and down, described pull bar is hexagon, this pull bar upper end is connected with a rod head through the circular hole at pull bar pressure cap top, lower end is formed with one or six rib heads, the cross section of described six rib heads is hexagon and this hexagonal diagonal is greater than the diameter of pull bar pressure cap top circular hole, the bottom of described six rib heads is also formed with the rounding conical surface, the barrel of described urceolus is distributed with many exhausting holes, wherein last exhausting hole is the inclined hole of downward-sloping setting, all the other through holes are axis and the orthogonal straight hole of urceolus axis, a plug variable buckle is connected with bottom described urceolus, described plug variable buckle top is formed with the taper seat of conjunction corresponding to inclined hole, described plug variable buckle upper end and described six rib head lower ends can fit together.
Angle between described inclined hole axis and urceolus axis is 45 °.
The beneficial effects of the utility model are: the utility model is designed to hexagon pull bar, the sector that between pull bar and barrel, formation six is little, increase quicksand passage, the clearance hole of outer tube wall lower bottom part is changed into the inclined hole of downward-sloping setting simultaneously, the interior end in cylinder, changes coned face into, is convenient to discharge sand and foreign material; The utility model efficiently solves the problem of bumper jar sand card.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
See Fig. 1 to Fig. 3, sands-proof check bumper jar of the present utility model comprises the pull bar pressure cap 2 and urceolus 4 that link together and to be arranged in pressure cap 2 and urceolus 4 and the pull bar 3 that can slide up and down, described pull bar 3 is hexagon, this pull bar 3 upper end is connected with a rod head 1 through the circular hole at pull bar pressure cap 2 top, lower end is formed with one or six rib heads, the cross section of described six rib heads is hexagon and this hexagonal diagonal is greater than the diameter of pull bar pressure cap 2 top circular hole, the bottom of described six rib heads is also formed with the rounding conical surface, the barrel of described urceolus 4 is distributed with many exhausting holes, wherein last exhausting hole is the inclined hole 6 of downward-sloping setting, all the other through holes are axis and the orthogonal straight hole of urceolus 4 axis, a plug variable buckle 7 is connected with bottom described urceolus 4, described plug variable buckle 7 top is formed with the taper seat 5 of conjunction corresponding to inclined hole 6, described plug variable buckle 7 upper end and described six rib head lower ends can fit together.Angle between described inclined hole 6 axis and urceolus 4 axis is 45 °.
Urceolus 4 is as screen casing, and wall distributes five exhausting holes, and top four is arranged as perpendicular to the straight hole of wall, and bottom one is arranged as 45° angle inclined hole 6, the corresponding conjunction of taper seat 5 of inclined hole 6 and plug variable buckle 7.
Plug variable buckle 7 is at urceolus 4 foot, and box in outer pin thread, pin thread front end is the conical surface, pin thread and urceolus 4 screwed connection, and the part reached in cylinder has taper seat 5, cuts away unnecessary part after screw thread puts in place, and the box of reprocessing plug, to connect other instruments.
The top of urceolus 4 is pull bar pressure cap 2, circular hole is arranged at pull bar pressure cap 2 top, and pull bar 3 can slide up and down in circular hole, but pull bar 3 bottom is six rib heads thicker than pull bar 3, six rib heads and pull bar pressure cap 2 play jarring action when clashing into, and prevent pull bar 3 from going out from cylinder lira simultaneously.
Pull bar 3 is hexagon, and top is with screwed connection rod head 1, and bottom is six rib heads, and the bottom of six rib heads becomes turbination, plays jarring action when six rib heads hitting pull bar pressure cap 2, ensures that pull bar 3 can not be deviate from cylinder simultaneously; When falling closed, plug variable buckle 7 upper end of six rib head lower ends and urceolus 4 bottom coincide.
The external diameter of rod head 1 is consistent with urceolus 4 diameter, and rod head 1 is connected with pull bar 3 with screw thread, and the other end is that pin thread is connected with other instruments.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but these embodiments are all included within scope of the present utility model.
