                            High Effective Hot Washing Anti-pollution String

1. Application 

It is used for wells with “low level, low liquid, low pump effective” to prevent leaking and protect layer during hot washing.

2. Structure and work principle

It is composed of Y221-114 self locking packer, sealing compensator,sieve tube and bottom ball seat. 

Y221-114 self locking packer:

   Total length: 1200mm     Max OD: φ114mm

Sealing compensator: 

   Total length: 16400mm    compensator length: 1100mm   Max OD:φ100mm  

3) Sieve tube: 

   Total length: 650mm       Max OD:φ73mm

Bottom ball seat:

   Total length: 270mm       Max OD:φ89mm

It’s installed under pump and above tail tube. It has no influence to uplink channel or liquid level monitoring during normal production. Meanwhile, reduce the back pressure of annulus to oil layer to produce in negative pressure. When hot washing, it can seal annulus and down channel of tubing below pump to prevent hot washing liquid leak into layer to pollute oil layer or make oil cannot be out. It saves washing water, improves efficiency and reduces cost. The most important is it prevents water go into oil. After hot washing, water discharging time is shortened, oil well production time is prolonged and crude oil output is increased.

3. Characteristics

 OD is Ф110mm and make it is easy to go down and not easy to stick pipe.

 Simple sealing, no need to add any other working process, low cost.

 Self-locking unit and sealing compensator are increased to eliminate influence to packer by string creeping in the pumping process and prolong the service life of string.

 Flushing channel is 100mm above rubber, so it’s easy to clean up sand or grits on the rubber completely and avoid packer stuck during washing.
