PRODUCT DESCRIPTION

The stage collar is an essential oil drilling tool utilized to control the circulation of drilling fluid and isolate varying formation pressures during the drilling process. Commonly made of metal, it features multiple holes of varying diameters, designed to regulate the flow rate and pressure of the drilling fluid at different stages of the drilling operation. The primary function of the stage collar is to prevent the drilling fluid from flowing from high-pressure formations to low-pressure formations, thus avoiding formation collapse and wellbore instability issues. It also assists drilling engineers in gaining a better understanding of formation pressures and characteristics, enabling them to formulate more effective drilling plans and optimize drilling performance.
