ROTARY STEERABLE TOOL

HH rotary steerable tool is the world’s first electronically controlled external pointing rotary steerable system with independent intellectual property rights and has applied for invention patents in many countries. HH rotary steerable system adopts oil seal technology, contact power and signal transmission technology, hydraulic control self-locking technology and mud hydraulic drive technology. It has the advantages of less electronic modules, independently-sealed compartment, simple and efficient mechanical structure, which can significantly reduce the energy consumption and cost. Battery power supply is available and the fabrication cost is less than 50% of that for existing rotary steerable tools in the market, which greatly reduces the use threshold and significantly improves the comprehensive economic benefits of complex and difficult drilling operations such as large displacement wells and horizontal wells.
