It is connected with change housing and shunting body, connecting portion has sealing element mutually to seal.Shunting body is one with mutually disconnected ten
The variable diameter cylindrical body of word cross-channel, one end are connected with piston, and another end seat is on spring pressure cap.Its inner wall has ball seat, steel
Ball seat is thereon.Upper and lower casing is connected on the external screw thread of upper and lower connector, and Qi Bishang has liquid flow hole.
The working principle of the utility model is: a certain layer is first exploited after driving a well, and when needing to change layer production, fixed tubular column, set
Pipe liquid feeding pressure pushes track pin to slide in the track, and changes layer by the realization of switching track switch state.When changing layer and obscuring,
It is different using high-low pressure track compression distance, low pressure is beaten by being repeated several times, track switch is returned to down fashionable switch state.
Compared with prior art, the utility model has the advantage that
1, the utility model is applied in combination, it can be achieved that multiple zone changes a layer control.
2, control realization is combined by high and low pressure and changes layer, because of compression distance difference, reduced switch state False Rate, change
Layer accuracy is high.
3, different using high-low pressure track compression distance when changing layer and obscuring, can by repeat to beat low pressure be restored to down it is fashionable
Original switch state, so as to avoid repeat change layer construction, reduce operating cost and labor intensity of workers, enhance scene
Management level.
The utility model is applied to non-homogeneous multi-layer system oil reservoir fixed tubular column and changes layer production, not only increases that change layer accurate
Degree, and original switch state fashionable under track switch can be restored to by liquid feeding pressure, it effectively prevents changing a layer confounding issues.
