Abstract
Provided is a layered filling sand prevention ball catching device. A ball blocking cover is placed between upper threads and lower threads inside a coupling, the upper portion of a locking-storing barrel is in threaded connection with the lower portion of the coupling after a spring and a locking claw are put into the locking-storing barrel, the spring presses the locking claw, the inner wall of the locking-storing barrel is provided with an expanding section, the diameter of a lower-portion port of the locking claw is smaller than the diameter of the upper portion to form a boss, the lower end of the locking claw is located under the expanding section on the inner wall of the locking-storing barrel, and the lower portion of the locking claw is milled to form a strip body. When a cleaned steel ball pushes the locking claw to ascend for a certain distance, the sprig is simultaneously compressed to store energy, the strip body formed by milling the lower portion of the locking claw is released and expands toward the expanding section arranged on the inner wall of the locking-storing barrel, the lower portion of the locking claw expands, the steel ball rolls into the locking claw to be caught, the energy stored by the spring enable the locking claw to descend, the lower portion of the locking claw contracts, and the steel ball is locked into the locking claw and falls no longer. When well washing operation is stopped, the steel ball can be dismounted and taken out. The layered filling sand prevention ball catching device can be matched with existing well mouth device to carry out sand production oil reservoir bottom filling and layered sand prevention process.
Description
Technical field
The utility model is the working device of oil field sand production petroleum reservoir bottom filling selective sand control, is that a kind of slicing and filling sand control is caught ball device.
Background technology
In sand production petroleum reservoir bottom filling selective sand control when construction, will make packer setting from dropping into steel ball in oil pipe, after packer setting completes, will set steel ball wash out to well head by anti-flushing well, stops well-flushing, and dismounting wellhead assembly takes out steel ball.Because wellhead assembly is airtight, stop steel ball after well-flushing and fall afterwards again, cannot obtain steel ball.Therefore, current wellhead assembly can not supporting enforcement sand production petroleum reservoir bottom filling selective sand control construction.
Summary of the invention
The purpose of this utility model is to provide a kind of slicing and filling sand control and catches ball device, and this device is arranged on wellhead assembly, the steel ball washing out can catch the construction of sand production petroleum reservoir bottom filling selective sand control time.
The purpose of this utility model is achieved in that and comprises box cupling, the cover of blocking, spring, lock pawl, lock is put cylinder, there are upper screw thread and lower screw thread in the inside of box cupling, the cover of blocking is placed between the upper screw thread and lower screw thread of box cupling inside, spring, lock pawl put into lock put cylinder after lock put cylinder top be connected with the lower thread of box cupling, lock put cylinder upper end withstand block cover lower surface, spring is pushed down lock pawl, lock on the inwall of putting cylinder expansion segment is set, the lower port diameter of lock pawl is less than upper diameter and forms boss, the lower end of lock pawl is in locking under the expansion segment on the inwall of putting cylinder, the bottom milling of lock pawl is split into bar body.
The beneficial effects of the utility model are: when the steel ball of washing up promotes the up location of lock pawl, spring is compressed storage power simultaneously, the bar body that the bottom milling of lock pawl is split into loses constraint, put the expansion segment place expansion arranging on the inwall of cylinder to lock, lock pawl bottom expands, steel ball enters in lock pawl and is hunted down, it is descending that the energy that spring stores promotes again to lock pawl, regain lock pawl bottom, steel ball is locked in pawl can not fall again, in the time stopping well-flushing, can pull down taking-up steel ball, the utility model can be with current wellhead assembly supporting enforcement sand production petroleum reservoir bottom filling selective sand control technique.
Accompanying drawing explanation
Accompanying drawing 1 is the half sectional view of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing 1, embodiment of the present utility model is described.
As seen from the figure, embodiment of the present utility model comprises box cupling 1, block and cover 2, spring 4, lock pawl 5, lock is put cylinder 6, there are upper screw thread and lower screw thread in the inside of box cupling 1, the cover 2 of blocking is placed between the upper screw thread and lower screw thread of box cupling 1 inside, spring 4, lock pawl 5 is put into lock and is put cylinder 6 rear locks and put cylinder 6 top and be connected with the lower thread of box cupling 1, the lower surface that lock is put cylinder 6 upper end and withstood the cover 2 of blocking, spring 4 is pushed down lock pawl 5, lock on the inwall of putting cylinder 6 expansion segment 7 is set, the lower port diameter of lock pawl 5 is less than upper diameter and forms boss 8, the lower end of lock pawl 5 is in locking under the expansion segment 7 on the inwall of putting cylinder 6, the bottom milling of lock pawl 5 is split into bar body, the bar body that the bottom milling of lock pawl 5 is split into is put cylinder 6 constraints by lock.Lock is put the junction installation sealing ring 3 of cylinder 6 and box cupling 1.
The internal diameter that the bar body that the bottom milling of lock pawl 5 is split into is put rear its boss 8 of cylinder 6 constraint by lock is less than steel ball size, the internal diameter of the bar body that the bottom milling of lock pawl 5 is split into its boss 8 after expansion segment 7 places expansion can be greater than steel ball size,, therefore, after steel ball is hunted down, can not fall again.The cover 2 of blocking can block steel ball and not depart from the utility model.
Claims (2)
1. a slicing and filling sand control is caught ball device, comprise box cupling (1), the cover (2) of blocking, spring (4), lock pawl (5), lock is put cylinder (6), it is characterized in that: there are upper screw thread and lower screw thread in the inside of box cupling (1), the cover (2) of blocking is placed between box cupling (1) inner upper screw thread and lower screw thread, spring (4), lock pawl (5) put into lock put cylinder (6) after lock put cylinder (6) top be connected with the lower thread of box cupling (1), the lower surface of cover (2) of blocking is withstood in the upper end that lock is put cylinder (6), spring (4) is pushed down lock pawl (5), lock on the inwall of putting cylinder (6) expansion segment (7) is set, the lower port diameter of lock pawl (5) is less than upper diameter and forms boss (8), the lower end of lock pawl (5) is in locking under the expansion segment (7) on the inwall of putting cylinder (6), the bottom milling of lock pawl (5) is split into bar body.
