80S STAGE COLLOAR , STAGE CEMENTING TOOLS, DRILLING TOOLS
The stage collar, or stage cement injector, is mainly used in multistage cement injection and cementing projects to achieve the cementing effect through stage cement injection and solve the problem of poor one-time cementing effect.
mainly the stage collar can be divided into three types:
1- Mechanical stage collar
2- Hydraulic stage collar
3- Needless drilling stage collar
