Downhole tools are complex electro-mechanical systems that perform critical functions in
drilling operations. The electronics within these systems provide vital support, such as …

Abrasive wear resulting from the microclastic rock is a common failure phenomenon in the
drilling environment that often limits the sealing ability and the service life of seals. In this …

The rotating speed of the downhole motor is very important to the drilling process, so it is
necessary to be measured in real-time. Here, a self-powered downhole motor rotating speed …

Pressure has a significant effect on rubber seal performance in the abrasive environments of
drilling. The micro-clastic rocks intruding into the seal interface are prone to fracture, which …
