ChenzhouCambered surface whipstock

The cambered whipstock is a normal type. The whipface is a circular arc surface, and has been super hardened. The whipface and the casing window milling cone have a high degree of agreement, and the righting effect is good. The opened window is regular, smooth and accurate; During the drilling process, the weight on bit is easy to control, which reduces get stuck and bit bounce, and reduces the occurrence of downhole accidents.

Product Description

The cambered surface whipstock (or the arc whipstock) is developed based no the ordinary whipstock. The whipface is a circular arc surface, and has been super hardened. The cambered surface whipstock and the casing window milling cone have a high degree of agreement, and the righting effect is good. The opened window is regular, smooth and accurate; During the drilling process, the weight on bit is easy to control, which reduces get stuck and bit bounce, and reduces the occurrence of downhole accidents.
