Abstract
The utility model relates to a quick blowout control tool, which comprises a tee joint, wherein a vertical passage with a first porthole and a second porthole and a lateral passage which is communicated with the vertical passage are arranged inside the tee joint, the opening of the lateral passage is of a third porthole, a gate is arranged at the third porthole, a blowout control press cover is arranged at the first porthole in a detachable way, and the second porthole is used for being connected with a large cross joint. The quick blowout control tool has simple structure and low production cost. When the blowout tread happens after a sucker rod is removed, the gate is opened to release the pressure, at the same time, the blowout control press cover is installed on the sucker rod, then the blowout control press cover is fixed at the first porthole or the second porthole, after the blowout control press cover is well fixed, the gate is closed, so the well sealing is completed, and the blowout is avoided. The above operation process is simple, the consumed time is short, and the well control requirement is reached.
Description
Technical field
The utility model relates to a kind of spray instrument of robbing fast, belongs to oil field prospecting development technique field.
Background technology
Enter development late stage in the oil field, kill job is not all carried out in many oil well operations, but carries out nearly balance or underbalance operation, very easily causes well kick when playing lower sucker rod, or even blowout.What crude oil was a large amount of during blowout is ejected into outside the well, substantially be in state out of control, there are serious safety problem and problem of environmental pollution, if blowout can not get preventing fast, can occur when serious that oil reservoir caves in, the accident of sleeve pipe damage, device damage and casualties.At present, used blowout hookup is that master valve is installed on upper flange when playing lower sucker rod, brought very big inconvenience for like this lower sucker rod operation, and must connect polished rod when well kick takes place and to realize closing well, whole process needs 10～20 minutes at least, far do not reach the well control requirement, lack control fast, very easily cause blowout out of control.
The utility model content
The purpose of this utility model provide a kind of simple in structure, easy to operate, rob the short spray instrument of robbing fast of spray time, in order to solve because of robbing the untimely problem that produces gas blowout accident of spraying.
For achieving the above object, the utility model adopts following technical scheme: a kind of spray instrument of robbing fast, this is robbed the spray instrument and comprises a threeway, be provided with Vertical Channel with first passage mouth and second channel mouth and the side path that is communicated with Vertical Channel in this threeway, the opening of side path is the third channel mouth, this third channel mouth place correspondence is provided with gate, and described first passage mouth place correspondence detachably is provided with robs the spray gland, and described second channel mouth is used for being connected with big four.
The described spray gland of robbing comprises a columnar shape basal, the middle part of this columnar shape basal is provided with an erection loop platform, the described spray gland of robbing is sealingly fastened in first passage mouth place by this erection loop platform, and the two ends of described columnar shape basal are coaxial to be provided with and to be used for the tapped blind hole that links to each other with sucker rod.
Described spray gland and the first passage mouth corresponding matching face place robbed is provided with metal o-ring.
The axis of described side path is vertical mutually with the axis of Vertical Channel.
Of the present utility modelly rob the spray instrument fast in use, at first this is robbed fast the spray instrument and be installed on the big four upper flange, at this moment, rob the spray gland and be separated with threeway.When the blowout omen takes place when, at first open the sluices, be screwed on the sucker rod robbing the spray gland simultaneously, and then use bolt will rob the spray gland seal to be fixed in the threeway, closed shutter is finished capping operation afterwards, has prevented the generation of blowout.Aforesaid operations can be finished in 3 minutes, had realized robbing fast spray, had reached the well control requirement.Simultaneously, this rob fast the spray tool construction simple, easy to operate, cost of production is low.
Simultaneously, the spray instrument of robbing fast of the present utility model, the side path of its threeway as pressure release passage, is convenient to rob the spray operation when robbing spray, in addition, had pressure release passage also to be convenient to control higher pressure.After well head was controlled, this side path can be used as the kill-job passage again and carries out the kill-job operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Shown in Figure 1, the spray instrument of robbing fast of the present utility model comprises a threeway 2, be provided with Vertical Channel with first passage mouth and second channel mouth and the side path that is communicated with Vertical Channel in this threeway 2, the axis of side path is vertical mutually with the axis of Vertical Channel, the opening of side path is the third channel mouth, and third channel mouth place is equipped with a gate 4 by clip 3 correspondences.Described first passage mouth place detachably is equipped with one by the bolt correspondence and robs spray gland 1, can certainly be arranged on second channel mouth place.Wherein, rob spray gland 1 and comprise a columnar shape basal, the middle part of this columnar shape basal is provided with an erection loop platform, the face that this erection loop platform cooperates with threeway is provided with first annular groove, threeway 2 is provided with second annular groove corresponding with above-mentioned first annular groove, a metal o-ring is installed in the fastening space of first annular groove and second annular groove, and this metal o-ring is used for realizing threeway 2 and robs the sealing of spraying between the gland 1.Also have, the two ends of described columnar shape basal are coaxial to be provided with and to be used for the tapped blind hole that links to each other with sucker rod.
When playing lower sucker rod, at first this is robbed fast the spray instrument and be installed on the big four upper flange, at this moment, rob the spray gland and be separated with threeway.When the blowout omen takes place when, at first open the sluices, be screwed on the sucker rod robbing the spray gland simultaneously, and then use bolt will rob the spray gland seal to be fixed in the threeway, closed shutter is finished capping operation afterwards, has prevented the generation of blowout.Aforesaid operations can be finished in 3 minutes, had realized robbing fast spray, had reached the well control requirement.
