Abstract
An annulus facture hanger solves the problem that the prior hanger is only capable of hanging an oil pipe yet incapable of preventing the oil pipe from being damaged by fracture sand. The utility model is provided with a body, and is characterized in that the lower end of the body is connected with a central tube, a long gum cover is sleeved on the central tube, and the lower end of the central tube is connected with a lower contact. The utility model has the advantage that the hanger is not only capable of hanging the oil pipe, but also capable of preventing the oil pipe from being damaged by fracture sand.
Description
Technical field
The utility model belongs to the oil field and hangs a kind of instrument that oil pipe is used, particularly a kind of annular space pressure break hanger.
Background technology
When down-hole, oil field oil reservoir need be implemented pressure break, to connect fracturing unit truck at well head four-way place usually at present, fracturing fluid and fracturing sand are squeezed into oil casing annular space with certain pressure.After fracturing sand enters annular space, at first be directly injected on the oil pipe, can cause very big infringement oil pipe.Existing hanger is to be made of the main body that two ends are equipped with internal thread, can only hang oil pipe, can not prevent the infringement of fracturing sand to oil pipe.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, and provides a kind of and can not only hang oil pipe, and can prevent that fracturing sand from causing the annular space pressure break hanger of infringement to oil pipe.
The utility model is achieved in that it has a main body, and its special character is: the lower end in main body is connected with central tube, is set with long gum cover on central tube, is connected with lower contact in the lower end of central tube.
Above-mentioned annular space pressure break hanger is set with O type circle and sealing ring on main body, described sealing ring is fixed by the nut that is located on the main body, to realize sealing.
Advantage of the present utility model is: can not only hang oil pipe, and be positioned at preventing rubber spare on this annular space pressure break hanger after installing, promptly long gum cover just in time is positioned at the fracturing sand eject position, makes fracturing sand going into well after the refraction on the long gum cover, has avoided the infringement of fracturing sand to oil pipe.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-main body, 2-O type circle, 3-sealing ring, 4-nut, 5-central tube, the long gum cover of 6-, 7-lower contact.
The specific embodiment
As shown in the figure, this annular space pressure break hanger has the main body 1 of a ladder tubulose, two ends in main body 1 all are processed with internal thread, top and middle part in main body 1 are respectively installed with O type circle 2, be set with sealing ring 3 in the middle and lower part of main body 1, described sealing ring 3 is by being located at nut 4 fixed limits of main body 1 bottom.By the central tube 5 that has been threaded, on central tube 5, be set with long gum cover 6 in the lower end of main body 1, be connected with lower contact 7 by external screw thread, be provided with external screw thread in the bottom of lower contact 7 in the lower end of central tube 5.
During installation, connect tubing head in the upper end of main body 1, by the oil pipe that is threaded, this annular space pressure break hanger is sat in the well head, push up on the main body 1 by the bolt that is located at well head four-way place and get final product in the bottom of lower contact 7.
Claims (2)
