Abstract
The utility model is related to a kind of automatically controlled releasing type hydraulic pressure capping toolses of water injection well Operating Pressure.Mainly solve the problems, such as that existing tubing string capping tools cannot block full tubing string completely.It is characterized in that：The halter（1）Bottom connects host（2）, host（2）Bottom connects hydraulic pump（3）, hydraulic pump（3）Bottom passes through releasing pup joint（4）Connect slip assemblies（5）, slip assemblies（5）Bottom is sequentially connected seal section component（6）, support claw（7）, support claw（7）Bottom is connected with deblocking solution anchor assemblies（8）, deblocking solution anchor assemblies（8）Bottom connects guide head（9）.The closure of oil pipe internal overflow when the automatically controlled releasing type hydraulic pressure capping tools of the water injection well Operating Pressure can realize operation lift pipe string prevents shaft bottom overflow outflow.
Description
Technical field
The utility model is related to oilfield, specifically a kind of automatically controlled releasing type hydraulic pressure closure work of water injection well Operating Pressure
Tool.
Background technology
Tubing string capping tools in oil field during existing Operating Pressure, simply capping tools Duan Shangyi root oil pipes, play pipe
Column could continue to construct to need to carry out bleeding off pressure during tool segment, it is impossible to realize the complete closure to full well casing column.
The content of the invention
In order to overcome the shortcomings of that existing tubing string capping tools cannot block full tubing string completely, the utility model provides one
The kind automatically controlled releasing type hydraulic pressure capping tools of water injection well Operating Pressure, the automatically controlled releasing type hydraulic pressure capping tools of the water injection well Operating Pressure
The closure of oil pipe internal overflow when can realize operation lift pipe string prevents shaft bottom overflow outflow.
The technical solution of the utility model is：A kind of automatically controlled releasing type hydraulic pressure capping tools of water injection well Operating Pressure, including
Halter, the halter bottom connect host, and host bottom connection hydraulic pump, hydraulic pump bottom passes through releasing pup joint connection card
Watt component, slip assemblies bottom are sequentially connected seal section component, support claw, and support claw bottom is connected with deblocking solution anchor assemblies, solution
Seal component bottom connection guide head of disanchoring.
The utility model has the advantages that：Due to taking said program, which applies in oil-field flooding
Tubing string closure during well workover operation construction with pressure, prevents that shaft bottom overflow is excessive, can realize to full well casing column everywhere
Closure, is the core process in Operating Pressure work progress.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
1- halters in figure, 2- hosts, 3- hydraulic pumps, 4- releasing pup joints, 5- slip assemblies, 6- seal section components, 7- branch
Support claw, 8- deblocking solution anchor assemblies, 9- guide heads.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, the automatically controlled releasing type hydraulic pressure capping tools of a kind of water injection well Operating Pressure, including halter 1, the horse
Leading 1 bottom connection host 2,2 bottom of host connection hydraulic pump 3,3 bottom of hydraulic pump connection releasing pup joint 4, releasing pup joint 4 with
Upper is downhole instrument host machine part, is closure seal section part below, and the shearing safety of circumference uniform distribution is equipped in back-off sub
Latch structure when reaching certain condition, cuts safety pin, and realization is given up, and downhole instrument host is separated with closure seal section.It gives up short
4 lower parts connection slip assemblies 5 are saved, slip assemblies are fixation means, by motor pushing voussoir slips opening are made to be stuck in pipe string internal wall
On, 5 bottom of slip assemblies connection seal section component 6, seal section component 6 is made of two groups of leather cups.6 bottom of seal section component connects
Support claw 7,7 bottom of support claw are connected with deblocking solution anchor assemblies 8, deblocking solution anchor assemblies 8 bottom connection guide head 9.
By the automatically controlled capping tools by test carriage tripping in designated depth, surface computer system control work before water filling well operations
Motor operating in tool drives the executive components such as hydraulic pump movement, press-in liquid band piston to cause support claw, slips, leather cup
Deng movement, the functions such as positioning, anchoring, closure are realized.Motor continues to be pressurized after closure so that and pressure continues to increase in hydraulic pump,
When the power that inside and outside differential pressure is acted in back-off sub is more than the shearing allowable of safety pin, safety pin is cut, downhole instrument host
It is separated with closure seal section, realization is given up.Seal section indwelling is blocked in down-hole string, the high pressure in hydraulic pump maintains leather cup swollen
The power of envelope and slips anchoring realizes self-locking.
