Hydraulic Rotary Casing Guider

when the casing encounters some shoulder during RIH, the self-rotating design of the guide head can automatically change direction and guide the casing successfully downward. Due to rotating by using fl -uid, during the RIH, in case of any mud cake, sand accumulation or partial hole shrinkage, it can be solved by pumping to circulate the drilling fluid to rotate the guide head to remove mud cake or sand, s o as to guide casing downward

Detailed Description

APPLICATION
when the casing encounters some shoulder during RIH, the self-rotating design of the guide head can automatically change direction and guide the casing successfully downward. Due to rotating by using fl -uid, during the RIH, in case of any mud cake, sand accumulation or partial hole shrinkage, it can be solved by pumping to circulate the drilling fluid to rotate the guide head to remove mud cake or sand, s o as to guide casing downward

FEATURES AND BENEFITS
1. The guide head can self rotate, and pumping can also make it self-rotate by drilling fluid.
2. It is applicable for vertical, directional, large-deviated and horizontal wells.
3. The roller is impregnated, which can reduce the drag during casing RIH.
4. The material is 40CrMnMo, with excellent mechanical property, meeting the anti-impact requirement during casing RIH.
5. The large flow area can meet the requirement of cementing operation.
