Title: Innovations of Jilei Niu in Downhole Technology
Introduction
Jilei Niu is a notable inventor based in Shandong, China. He has made significant contributions to the field of downhole technology, holding a total of 6 patents. His work focuses on enhancing drilling efficiency and effectiveness through innovative devices.
Latest Patents
One of Jilei Niu'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 comprises an electromagnetic valve seat, a pressurizing chamber, and a discharge flow pup joint. An electromagnetic valve is integrated into the valve seat, which also contains a flow channel. The design includes a plunger that separates the pressurizing chamber into non-rod and rod chambers, along with a conveying pipe in the discharge flow pup joint that forms a flow channel with it. The drill bit connects to the discharge flow pup joint, enhancing drilling capabilities.
Another significant invention by Niu is a 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 that reduce friction. During the axial reciprocating motion of the upper vibration starter, a spring compresses periodically, generating spring energy. This energy acts on the lower vibration starter and the main shaft connected to the drill bit, providing periodic drilling pressure. The periodic motion creates axial vibration on the tool, improving drilling performance.
