Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
As Figure 1-Figure 5, the utility model includes base tube, outer tube, adjustable pipe, activity magnetic cell, fixed magnetic cell,
Wherein base tube both ends are connected by connection screw thread with Oil/Gas Pipe, and base tube one end offers flowing hole, and overcoat is fixed with outside on base tube
Sleeve pipe, outer tube both ends connect with base tube outer wall into closing, certain space are formed between outer sleeve inner wall and base tube outer wall, activity
Pipe is embedded in the fixation pore opened up on outer tube, and can along fixed pore interior axle to moving and connection closed at both ends, Gu
Determine magnetic cell and be embedded in one end that outer tube fixes pore, activity magnetic cell is embedded in one end of adjustable pipe, activity magnetic cell with
Fixed magnetic cell has same pole.The structure of the embodiment employs magnetic coupling technology, using the movable magnetic list of same pole
Member and fixed magnetic cell, are separately positioned on the end of adjustable pipe and fixed pore, utilize the interaction between two magnetic cells
Adjustable pipe stress is in poised state, and can be adjusted in the case that adjustable pipe changes in stress by the motion of adjustable pipe
The distance between whole two magnetic cells, can be to underground by the action real-time change of adjustable pipe so as to continue to poised state
Quicker reaction is made in fluid flow state change, and viscosity is applied widely, reaches the effect of real-time flow control, highly effective
The appearance of water cone gas coning is prevented, improves ultimate recovery.
Further, we coordinate water-swellable material technology, i.e., in adjustable pipe while using magnetic coupling technology
Water-swellable unit is set on wall, and when flowing into aqueous fluid in pit shaft, water-swellable unit is met water and is radially expanded, radially swollen
Caliber diminishes at water-swellable unit after swollen, and the local resistance of convection body becomes big, fluid-pressure drop increase.Water content is bigger, meets water
Expansion cell expansion is bigger, and the local resistance of convection body is bigger, and now total pipe range is determined by fluid water content and flow combination, always
Pipe range refers to that fixing pipe hole length subtracts the two plus movable length of tube and overlaps length.Physical principle i.e. of the present utility model is logical
Cross：Journey resistance combination local resistance is adjusted by the pressure drop after pipe.
In the present embodiment, as shown in figure 4, the excessively stream bore dia that base tube one end is set is determined by flow in real well.
