Latest Patents

One of Hualin Liao's latest inventions is the electromagnetic reversal downhole pressure intensifier. This device includes a pressure intensifier and a drill bit, featuring a nozzle and a bit waterway. The pressure intensifier consists of an electromagnetic valve seat, a pressurizing chamber, and a discharge flow pup joint. An electromagnetic valve is integrated into the valve seat, while a plunger in the pressurizing chamber separates it into non-rod and rod chambers. The drill bit connects to the discharge flow pup joint, enhancing drilling capabilities.

Another significant invention is the drilling speed increasing device driven by a downhole motor for generating shock vibration. This device utilizes the rotational energy of a screw motor to drive a lower vibration starter. The design incorporates vibration starting steel balls to reduce friction. The upper vibration starter undergoes axial reciprocating motion, compressing a spring to generate energy that periodically provides drilling pressure for the drill bit. This innovation results in periodic axial vibration, improving drilling efficiency.
