The suspension device is characterized in that the upper flange is a pot shape, a pot mouth is a shell head which is connected with a valve of a bushing; an inner diameter of the upper flange is a step shape, the upper part is smaller than the central part, and the central part is smaller than the lower part, the upper and the central parts are respectively provided with inner cone tube screw thread to connect with a three-way of an oil pipe and the inner cone tube screw thread connecting with the oil pipe, and the lower part is provided with a bushing cavity; the lower flange is an I-shape, the upper part of the lower flange is provided with the inner cone tube screw thread, and the lower end of the lower flange is welded with a ring steel plate, a bushing hanger with the inner tube screw thread at the upper and the lower parts is arranged between the ring steel plate and the inner tube screw thread at the upper part of the lower flange, the bushing hanger is connected with the inner tube screw thread at the upper part of the lower flange through casing nipple, and the lower inner tube screw thread of bushing hanger is connected with the bushing.
Description
One, technical field
The utility model relates to a kind of simple and easy tubing and casing suspension arrangement of oil well mouth usefulness.
Two, technical background
Boll-weevil hanger on the production tree of using on the oil field is provided in a side of a four-way junction of casing the inside at present, for gas-liquid in the oil pipe and the gas-liquid in the sleeve pipe are separated, and on production tree, demonstrate oil pressure and casing pressure, the fixed position of boll-weevil hanger and the design of sealing position are complicated, and construction and installation are trouble.The clip head of in addition pacifying sleeve valve when to the oil well job execution, influences the operating worker operation at following of four-way junction of casing upper flange; Sleeve pipe cooperates with the lower flange of four-way junction of casing with the casing flange of directly screwing on sleeve pipe being connected of four-way junction of casing, uses the stud fixed by nut.The sleeve pipe part of basseting.When oil well stopped well, common people were just sawed-off in sleeve position with hacksaw.Whole production tree stolen sell iron and steel, directly influence the normal operation construction of oil well.Bring immeasurable economic loss to the oil field.
Three, summary of the invention
The utility model has designed a kind of simple and easy tubing and casing hanger at the problem of above-mentioned existence.
The technical solution of the utility model realizes by mode once:
The utility model is made up of the single ended bolt of lower flange in upper flange, lower flange, the connection, the steel ring that is installed between the lower flange, it is characterized in that upper flange is kettle shape, Hu Zui is made as the clip head of splicing sleeve valve, its upper flange internal diameter is made as stairstepping, top is less than the middle part, the middle part is less than the bottom, and top is provided with endosiphuncular tube screw thread that is connected with the oil pipe threeway and the endosiphuncular tube screw thread that is connected with oil pipe (claiming boll-weevil hanger or oil pipe hanging head) separately with the middle part, and the bottom is made as casing cavity; It is I-shaped that lower flange is, lower flange top is provided with the inner conical gas thread, the lower flange lower end is welded with doughnut-shaped steel plate, between doughnut-shaped steel plate and lower flange top endosiphuncular tube screw thread, be provided with up and down casing hanger with the endosiphuncular tube screw thread, be connected with casing nipple between casing hanger and the lower flange top endosiphuncular tube screw thread, the endosiphuncular tube screw thread is connected with sleeve pipe under the casing hanger; The wall thickness of lower flange is more than 20mm, and last lower flange is connected to single ended bolt and connects, and lower flange is provided with the internal thread of single ended bolt, and last lower flange is cast with cast steel.
The utility model installing/dismounting simple in structure, easy, convenient working construction.Lower flange gets up casing protection, wall thickness in addition, and common people are not easy sawed-off, have guarded against some people's pilferage behavior preferably, have protected the oil field property.
Four, description of drawings
The structural representation of Fig. 1-simple and easy tubing and casing suspension arrangement.
Five, embodiment
In order further to disclose the technical solution of the utility model,, be described in detail by embodiment below in conjunction with Figure of description:
The utility model is made up of the single ended bolt 2 of lower flange in upper flange 1, lower flange 4, the connection, the steel ring 3 that is installed between the lower flange, it is characterized in that upper flange is kettle shape, Hu Zui is made as the clip head of splicing sleeve valve, its upper flange internal diameter is made as stairstepping, top is less than the middle part, the middle part is less than the bottom, and top is provided with endosiphuncular tube screw thread that is connected with the oil pipe threeway and the endosiphuncular tube screw thread that is connected with oil pipe (claiming boll-weevil hanger or oil pipe hanging head) separately with the middle part, and the bottom is made as casing cavity; Lower flange 4 is I-shaped, lower flange top is provided with the inner conical gas thread, the lower flange lower end is welded with doughnut-shaped steel plate 7, between doughnut-shaped steel plate and lower flange top endosiphuncular tube screw thread, be provided with up and down casing hanger 6 with the endosiphuncular tube screw thread, be connected with casing nipple 5 between casing hanger 6 and the lower flange 4 top endosiphuncular tube screw threads, 6 times endosiphuncular tube screw threads of casing hanger are connected with sleeve pipe 8.
The concrete installation process of the utility model is as follows:
At first casing hanger 6 is connected with sleeve pipe 8, be connected with casing nipple 5 again, casing nipple 5 is threaded with lower flange 4 endosiphuncular tubes again, doughnut-shaped steel plate 7 is two of symmetry, on its sleeve pipe to the lower end that is buckled in lower flange, the make-up of burn-oning seam, again that itself and lower flange lower end is welded together, put steel ring 3 in the lower flange upper surface, the pipe elevator of slinging.The suspension oil pipe endosiphuncular tube screw thread of upper flange 1 is connected with oil pipe, again 1 pair of upper flange is buckled on the lower flange 4, the single ended bolt 2 of screwing on, again the oil pipe threeway is connected with the upper flange upper end, sleeve valve will be installed again on the upper flange, preventer is installed in upper end in the oil pipe threeway, installs tubing valve at the other end, promptly constitutes a complete production tree.
