Abstract
The utility model relates to a circulative sieve tube hanger which comprises a connecting rod; one end of the connecting rod is connected with a feeding connector; a drill rod rubber plug is arranged in the feeding connector; and an expansion tube is sleeved at the external end of the connecting rod. The circulative sieve tube hanger is characterized in that the other end of the connecting rod is connected with a tail tube rubber plug; a tie-back sleeve is sleeved outside the tail tube rubber plug; and one end of the tie-back sleeve far away from the tail tube rubber plug is connected with a touch-press connector. With the adoption of the technical scheme provided by the utility model, the effective circulative well-flushing can be realized in a process of sieve tube insertion; and meanwhile, whole-section circulative well-flushing can also be carried out after a well-completion sieve tube is inserted into the well bottom, and an outer ring of a well-completion fluid replacement sieve tube can also be protected from emptying slurry by using lightweight oil or a reservoir. The circulative sieve tube hanger has the advantages of simple structure, simplicity and convenience in use, can realize circulative well-flushing effectively and has good well-flushing effect.
Description
Technical field
The utility model relates to a kind of OCTG, relates to a kind of employed screen pipe hanger capable of circulation when in the oil exploitation process, drilling well being repaired specifically.
Background technology
In the operation of horizontal well cased hole completion, well sand setting, borehole status are bad, the mill resistance is bigger etc. all can cause completion casing or screen insertion difficulty, in oil field operation, after all setting of casings are hampered, on put pressure when all ineffective, circulation well cleanup usually can unfreezing.Cutting on the screen casing string in full slit, because drilling fluid or completion flow are anterior less than the screen casing that needs most flushing, can only short-circuit cycle, and can't carry out effective circulation well cleanup.
The utility model content
The problem that the utility model will solve is to above problem, and a kind of screen pipe hanger capable of circulation of effectively circulation well cleanup is provided.
For addressing the above problem, the technical scheme that the utility model adopted is:
Screen pipe hanger capable of circulation; Comprise connecting rod, an end of connecting rod is connected with sends into joint, sends into and is provided with the drilling rod plug in the joint; The outer end of said connecting rod is socketed with expansion tube; It is characterized in that: the other end of said connecting rod is connected with the tail pipe plug, and the outside of said tail pipe plug is with the tieback tube, and the tieback tube is connected with the bruising joint away from an end of tail pipe plug.
As a kind of improvement:
Said connecting rod is connected with mother, nut and the plug that expands fully in turn near an end of tail pipe plug.
As further improvement:
Said connecting rod is provided with centering ring away from an end of tail pipe plug, and centering ring is fixed through shear pin and expansion tube.
The utility model is through taking above technical scheme; Can be implemented in the process of screen insertion effectively circulation well cleanup, can also behind the shaft bottom, carry out full section circulation well cleanup under the completion screen casing simultaneously, can also be with light oil or the outer annular space mud of oil layer protection completion fluid displacement screen casing; The utility model is simple in structure; Use simple and convenient, circulation well cleanup effectively, well washing effect is good.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
