Abstract
The utility model relates to a shearing type pipe controlled oil draining device, which is used for the oil drainage of the production of pumping wells and the downhole operation. The utility model is composed of an inner and an outer working barrel 8, 2, a shearing pin 5, a positioning pin 3, sealing pads 4, 6, and a sealing ring 7 which are in the inner and the outer working barrel 8, 2, and oil pipe buckle changing joints 1, 9 connected to the upper and the lower ends. The utility model has the advantages of simple structure, simple manufacture, convenient operation, and reliability operation. By utilizing the utility model, the oil drainage can be favorably carried out at the of the workover treatment of the pumping wells; even when a sucker rod is broken off, clamped, or slipped, etc., the opening of the utility model can not be affected, and the pollution of a well site can be avoided. The utility model can be reused, and the production cost can be reduced.
Description
The utility model relates to a kind of downhole hardware that is used for pumpingh well production and underground work.
When pumpingh well underground work lift pipe string, often run into situations such as sucker rod breaks, blocks, takes off.At this moment, the on-the-spot at present bleeder that passes through its unlatching of sucker rod action control that uses can't be opened, and makes that the profit in the oil pipe can't be excreted in the pit shaft, have to take ground to oil pipe, cause well head place pollution in wide area, simultaneously, play the pipe operation for the operation worker and bring very big inconvenience.
The purpose of this utility model be to provide a kind of can break, block, take off under the situation at pumpingh well underground work generation sucker rod still can open draining smoothly, thereby the shearing management and control bleeder of avoiding the well site to pollute.
The utility model is to realize like this.This kind bleeder is by interior, outer working tube and the shear pin that is installed in wherein, shop bolt, potted component and tipping are last, the oil pipe at following two ends becomes the snapping head and forms, its structure, assembled relation is as follows: the interior seating nipple that " O " shape sealing ring is housed in the seal groove places in the outer working tube, its upper end step seat is placed on the inner headed face step of outer working tube bottom, the shop bolt that is set with the red copper sealing mat is screwed in the dowel hole on the outer working tube, and tighten in the axial elongated slot of seating nipple upper end in inserting, 2 shear pins that are set with the red copper sealing mat are screwed into respectively in 2 shear pinhole on the outer working tube and tighten; Outer working tube upper end and interior seating nipple lower end have oil pipe to become the snapping head by the screw thread tipping respectively.This bleeder is connected on the above position of oil well pump top 3-5 root oil pipe.The normal oil recovery when producing, interior seating nipple and the impact force action that produces with the gravity of lower tubular column with when bumping pump thereof are on the step between the inside and outside seating nipple, because the sealing of " O " shape rubber seal is arranged between the inside and outside seating nipple, the sealing of red copper sealing mat is all arranged between outer working tube and shear pin and the shop bolt, thereby can guarantee when the oil well ordinary production oil-proof.During the workover treatment lift pipe string, at first deepen tubing string and gently visit the sand face, back pressurization 3-5 ton is hampered, shear pin is cut off, the upper lifting pipe post, because shop bolt can guarantee not relatively rotate between the inside and outside seating nipple, shear pinhole this moment (being the draining hole) is exposed, thereby smooth draining lift pipe string can be guaranteed the time, and avoid polluting the well site.After this bleeder tripped out from well, through inspection, as there not being obvious erosion on the inside and outside seating nipple, the step place is obviously distortion and wearing and tearing not, behind replacing shear pin and the seal, can repeat the use of going into the well.
The utility model is simple in structure, is easy to make, and is easy to use, reliable operation, utilize it can be when the pumpingh well workover treatment smooth draining, do not influence its unlatching even sucker rod such as breaks, blocks, takes off at fault yet, thereby avoid the well site pollution.This kind bleeder is reusable, helps reducing production costs.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing enforcement of the present utility model is described further.
As shown in the figure, the utility model is formed total length 700mm by oil pipe change snapping head 1,9, outer working tube 2, shop bolt 3, shear pin 5, sealing mat 4,6, sealing ring 7, interior seating nipple 8.Wherein, outer working tube 2 is Φ 112 cylinders, and its upper end inner headed face is provided with the screw thread bottom and is provided with a step, and the barrel middle part is provided with threaded shop bolt through hole, and inner headed face step top is provided with 2 relative threaded shear pin through holes.Interior seating nipple 8 is the cylinder that an external diameter and outer working tube internal diameter match, its periphery upper end wall thickness is bigger, the step that formation one and outer working tube inner headed face step match under it, the step below is provided with 3 road seal grooves, the lower end is provided with pin thread, the barrel upper end is provided with the axial elongated slot relative with the outer working tube dowel hole, and both sides are provided with 2 radially draining holes relative respectively with the outer working tube shear pinhole.
