Abstract
The utility model relates to a screen pipe hanger for petroleum drilling, comprising an adapter, a connecting pipe, an expansion pipe and a tie-back drum, wherein one end of the expansion pipe is connected to the adapter and the other end thereof is connected to the tie-back drum; one end of the connecting pipe is connected to the adapter and the other end thereof is connected to a tail pipe; the tail pipe is fixedly connected through a shear pin; a stabilizing ring is sleeved to the end of the connecting pipe which is connected with the adapter; the stabilizing ring is fixedly connected to the expansion pipe through the shear pin; an expansion plug and a nut are sleeved to the end of the connecting pipe which is connected to the tail end; a connecting base is arranged on the lower part of the tie-back drum; a drill rod is arranged in the adapter; and rubber plugs are arranged on the drill rod and the tail pipe. Effective circulating well washing in the setting process of the screen pipe can be realized, and simultaneously, full-section circulating well washing can be performed after the well completion screen pipe reaches the bottom of the well; besides, annular mud outside the screen pipe can be replaced by a light oil or an oil layer protective well completion fluid. The screen pipe hanger for petroleum drilling is simple in structure, convenient for use, capable of effectively performing circulating well washing, and good in well washing effect.
Description
Technical field
The utility model relates to a kind of petroleum drilling and mining and uses device, specifically, relates to a kind of petroleum drilling and mining and uses screen pipe hanger.
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, provides a kind of effectively petroleum drilling and mining of circulation well cleanup to use screen pipe hanger.
For addressing the above problem, the technical scheme that the utility model adopted is: a kind of petroleum drilling and mining is used screen pipe hanger, comprises junction block, tube connector, expansion tube and tieback tube; One end of said expansion tube is connected with junction block, and the other end of said expansion tube is connected with the tieback tube, and an end of said tube connector is connected with junction block; The other end of said tube connector is connected with tail pipe; Said tail pipe is fixedly connected through shear pin, and the end that said tube connector is connected with junction block is set with centering ring, and said centering ring is fixedly connected with expansion tube through shear pin; The end that said tube connector is connected with tail pipe is set with expand plug and nut; The bottom of said tieback tube is provided with Connection Block, is provided with drilling rod in the said junction block, and said drilling rod and tail pipe are provided with plug.
A kind of concrete prioritization scheme, the quantity of said nut are two.
The utility model is taked above technical scheme; Have the following advantages: 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; Easy to use, circulation well cleanup effectively, well washing effect is good.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
