Description
Technical field
The utility model relates to a kind of oil-water well with intubate packer hydraulic setting instrument, belongs to the oil recovery field.
Background technology
Along with the generally use at home of intubate packer, it is particularly important that the performance of its matching used setting tool seems.At present, the intubate packer setting tool is divided into three kinds of mechanical setting tool, cable setting tool and hydraulic setting instruments, but they all have certain limitation.Machinery setting tool unfailing performance is low, particularly for some high angle holes, packer is sat extremely fully; The cable setting tool need be lowered to cable, and construction is inconvenient, and cost is higher; The easy construction of hydraulic setting instrument, cost is low, but existing hydraulic setting instrument is put difficulty aside after setting, and when giving up, tubing string load and pipe internal pressure change all not obvious, cause erroneous judgement easily.
The utility model content
In view of the problems referred to above that exist in the existing intubate packer setting tool technology, main purpose of the present utility model is to address the deficiencies of the prior art, a kind of intubate packer hydraulic setting instrument is provided, has been mainly used in setting of oil-water well down-hole intubate packer.
Technical solution of the present utility model is, a kind of intubate packer hydraulic setting instrument is provided, described hydraulic setting instrument by upper center tube, top connection, upper piston tube, upper piston, middle piston, middle piston cylinder, lower piston, lower piston tube, sealing drum, lower center tube, locking cap, set tube, pull bar, ball seat, steel ball etc. and form.Described upper center tube is contained in the top connection, can move up and down in top connection, is connected with upper piston down; Piston, lower piston, lower center tube all have the side fluid hole to communicate with corresponding hydraulic cavities in described.Described ball seat is contained in the pull bar bottom, in steel ball is arranged, four fluid holes are arranged all around, fluid hole respectively has one O-ring seals up and down; Described ball seat is when work, and ball seat top discharges ring top with the intubate packer and is threaded, and insert in the intubate packer inner central tube ball seat bottom, by O-ring seals and steel ball sealing, forms enclosed cavity.
Preferably, described upper center tube is contained in the top connection, can move up and down in top connection.
Preferably, described ball seat is contained in the pull bar bottom, in steel ball is arranged, four fluid holes are arranged all around, fluid hole respectively has one O-ring seals up and down.
Compared with prior art, advantage of the present utility model and beneficial effect are:
1, hydraulic setting instrument of the present utility model sets dependable performance, and is simple to operate.
2, hydraulic setting instrument of the present utility model is easy to put aside and slips out of the hand, and is setting follow-up high pressure of continuing rising, and then three grades of fluid cylinders of hydraulic drive and upper center tube move up, and pulling pull bar and ball seat are up, are easy to break the release ring of intubate packer, thereby slip out of the hand.
3, hydraulic setting instrument of the present utility model is easy to judge whether the release ring of intubate packer is cut off slips out of the hand, after the release ring is cut off and is slipped out of the hand, hydraulic pressure continues to promote fluid cylinder and ball seat moves up, and abdicates the fluid hole pressure release, and the pressure in tubing string changes and can judge whether exactly to slip out of the hand.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model provides a kind of intubate packer hydraulic setting instrument.
As shown in Figure 1, the preferred hydraulic setting instrument of the utility model comprises upper center tube (1), top connection (2), upper piston tube (3), upper piston (5), middle piston (8), middle piston cylinder (7), lower piston (10), lower piston tube (9), sealing drum (11), lower center tube (12), locking cap (13), sets tube (14), pull bar (16), ball seat (17), steel ball (19) etc.Upper center tube (1), upper piston (5), middle piston (8), lower piston (10), lower center tube (12), pull bar (16), ball seat (17) are threaded successively; Upper piston tube (3), middle piston cylinder (7), lower piston tube (9), sealing drum (11), locking cap (13), set the tube (14) be threaded successively.
As a kind of preferred version of the present utility model, upper center tube (1) is contained in the top connection (2), can move up and down in top connection (2), is connected with upper piston (5) down.
As a kind of preferred version of the present utility model, ball seat (17) is contained in pull bar (16) bottom, in steel ball (19) is arranged, four fluid holes are arranged all around, fluid hole respectively has one O-ring seals (18) up and down.
As a kind of preferred version of the present utility model, ball seat (17) is when work, and ball seat (17) top discharges ring top with the intubate packer and is threaded, and insert in the intubate packer inner central tube ball seat (17) bottom, by O-ring seals (18) and steel ball (19) sealing, form enclosed cavity.
When the utility model uses, the screw thread on the hydraulic setting instrument ball seat (17) is connected with release ring on the intubate packer, screws up with a wrench; To set tube (14) and twist down, and make it rigidly connect the upper joint sleeve that contacts intubate packer upper end, and twist back locking cap (13) locking at last and set tube.
After the instrument connection finishes, as requested the intubate packer is arrived setting depth down, just suppressing and setting, fluid pressure in the oil pipe passes to by upper piston tube (3), middle piston cylinder (7), lower piston tube (9) and sealing drum (11) and sets tube (14), make between the pull bar (16) that sets tube (14) and inside and produce relative displacement, thereby set following intubate packer.Behind packer setting, continue fluid pressure in the rising oil pipe, because packer set and made that setting tube (14) can not move down this moment, then hydraulic drive upper piston (5), middle piston (8), lower piston (10) and upper center tube (1) move up, pulling pull bar (16) and ball seat (17) are up, break the release ring of intubate packer, thereby slip out of the hand.After the release ring is cut off and is slipped out of the hand, hydraulic pressure continues to promote upper piston (5), middle piston (8), lower piston (10) and ball seat (17) and moves up, ball seat (17) pipe in the intubate packer is extracted, expose the fluid hole pressure release, pressure descends, and this is that pressure in the tubing string changes and can judge whether exactly to slip out of the hand.
By optimal design of the present utility model and structure, can set the intubate packer better, it is easy to operate, is easy to slip out of the hand and judge, and cost is low.
Above-described only is preferable possible embodiments of the present utility model; described embodiment is not in order to limit scope of patent protection of the present utility model; therefore the equivalent structure done of every utilization manual of the present utility model and accompanying drawing content changes, and in like manner all should be included in the protection domain of the present utility model.
