Abstract
The utility model provides a drillable under-well tool anti-setting in midway device and relates to the anti-setting in midway device in the operation of oil well, comprising a central pipe, a cap, an upper slip, a lower slip, an upper cone, a lower cone, an anti-setting locking ring and a rubber cylinder, wherein, the central pipe is provided with the cap, the upper slip, the upper cone, the rubber cylinder, the lower cone and the lower slip from the top down; the anti-setting locking ring is sleeved on the central pipe and is connected with the upper cone through a thread, the top of the anti-setting locking ring props up against a lug boss on the central pipe, a sliding chamber is arranged between the lug boss and the upper cone; the lower slip is connected with the central pipe through a thread. With reasonable and compact structure, the utility model can effectively prevent the drillable under-well tool from setting in midway in the process of entering a well, thereby the security of the drillable under-well tool in the job location is improved and the risk of construction is reduced.
Description
One, technical field
The utility model relates to the anti-seating and sealing unit midway in the oilfield operation, is a kind of anti-seating and sealing unit midway of class downhole tool that bores.
Two, background technology
At present, the construction one-time success rate that can bore the class downhole tool both at home and abroad is about 85%, often generation can be bored the class downhole tool and produce situation about setting midway in being gone into the process of well, just have only the operation requirement comparatively harsh if will further improve success rate to on-site construction operations personnel proposition, cause that labor intensity of operating personnel increases, efficiency of construction is low, and have potential safety hazard.
Three, summary of the invention
The utility model provides a kind of anti-seating and sealing unit midway of class downhole tool that bores, and has overcome the deficiency of above-mentioned prior art, can effectively prevent to bore the class downhole tool and produce the situation generation that sets midway in going into the process of well.
The technical solution of the utility model realizes by following measure: a kind of anti-seating and sealing unit midway of class downhole tool that bores comprises central tube, pressure cap, upper slips, lower slips, upper cone, lower cone, anti-lock ring and the packing element of setting; Central tube is equipped with pressure cap, upper slips, upper cone, packing element, lower cone and lower slips from the top down in regular turn; Anti-set lock ring and be sleeved on the central tube, anti-ly set lock ring and link together, prevent setting the lock ring top and withstand on the boss on the central tube, between boss and upper cone, sliding cavity is arranged by screw thread and upper cone; Lower slips links together by screw thread and central tube.
Be further optimization and/or improvements below to above-mentioned technical solutions of the utility model:
Between above-mentioned packing element and the upper cone packing element upper baffle ring can be arranged, the packing element upper baffle ring is enclosed within on the central tube.
Between above-mentioned packing element and the lower cone packing element lower baffle ring can be arranged, the packing element lower baffle ring is enclosed within on the central tube.
Above-mentioned lower slips following can have can limit the rule ring that lower slips moves down, and the rule ring is installed on the central tube.
The utility model reasonable and compact in structure can effectively prevent to bore the class downhole tool situation about midway setting takes place in going into the process of well, has improved the safety that can bore class downhole tool site operation, has reduced construction risk.
Four, description of drawings
Accompanying drawing 1 is looked the broken section structural representation for the master of the utility model most preferred embodiment;
Coding in the accompanying drawing is respectively: 1 is pressure cap, and 2 is upper slips, and 3 is central tube, and 4 is upper cone, and 5 is to prevent setting lock ring, and 6 is the packing element upper baffle ring, and 7 is packing element, and 8 is the packing element lower baffle ring, and 9 is lower cone, and 10 is lower slips, and 11 are the rule ring.
Five, the specific embodiment
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
As shown in Figure 1, this can bore the anti-seating and sealing unit midway of class downhole tool and comprises central tube 3, pressure cap 1, upper slips 2, lower slips 10, upper cone 4, lower cone 9, anti-lock ring 5 and the packing element 7 of setting; Central tube 3 is equipped with pressure cap 1, upper slips 2, upper cone 4, packing element 7, lower cone 9 and lower slips 10 from the top down in regular turn; Anti-set lock ring 5 and be sleeved on the central tube 3, anti-ly set lock ring 5 and link together, prevent setting lock ring 5 tops and withstand on the boss on the central tube 1, between boss and upper cone 4, sliding cavity is arranged by screw thread and upper cone 4; Lower slips 10 is connected with central tube 3 by screw thread, like this, lower slips 10 can not move upward, make and to bore the upwards friction that produces in the process that the class downhole tool is lowered to decompose on the central tube 3 in oil well, make cone and slips can not produce relative displacement, can prevent effectively that lower cone 9 from strutting lower slips 10.
Can according to actual needs the above-mentioned anti-seating and sealing unit midway of class downhole tool that bores be made further optimization and/or improvements:
As shown in Figure 1, between packing element 7 and the upper cone 4 packing element upper baffle ring 6 is arranged, packing element upper baffle ring 6 is enclosed within on the central tube 3.
As shown in Figure 1, between packing element 7 and the lower cone 9 packing element lower baffle ring 8 is arranged, packing element lower baffle ring 8 is enclosed within on the central tube 3.
As shown in Figure 1, move down in order to prevent lower slips 10, have below lower slips 10 and can limit the rule ring 11 that lower slips 10 moves down, rule ring 11 is installed on the central tube 3.
Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.
The concrete use of the utility model most preferred embodiment is as follows: because the boss on the central tube 3 makes the anti-lock ring 5 drive upper cones 4 that set to move downward, lower slips 10 is threaded with central tube 3 usefulness, lower slips 10 can not move upward, make and to bore the upwards friction that produces in the process that the class downhole tool is lowered to decompose on the central tube 3 in oil well, cone and slips can not produce relative displacement, prevent that effectively cone from strutting slips, so just played the anti-effect that sets midway.In the time of can boring the class downhole tool and arrive the precalculated position and need work, effect lower center tube 3 in external force is upwards stressed, pressure cap 1 promotes upper cone 4, anti-sets lock ring 5 under the effect of downward force, packing element upper baffle ring 6 moves downward compression packing element 7 along central tube 3, packing element 7 promotes packing element lower baffle ring 8 simultaneously, lower cone 9 moves downward, lower cone 9 produces radial load and struts lower slips 10, it is anchored on the casing wall, after packing element 7 is compressed fully, upper cone 4 generation radial loads strut upper slips 2 is anchored on the casing wall it, has just realized boring setting of class downhole tool.
