Some problems such as high cost of tripping the tubing string, limited injection pressure and insufficient gas supply will be faced when gas lift is used as an artificial lift method for deep Wells.
This plugging technology uses tubing to carry plugging agent, and is characterized by less volume of agent, thin plugging, highpressure bearing and easy unplugging.
该工艺采用油管携带堵剂的方式，具有堵剂用量少、堵得浅、承压强度高、工艺简便、易解堵等特点。

The fiction can prevent large loads caused by highpressure and high temperature from spreading, which can result in severe deformation in a short part of tubing.
