发明名称 Reinforced directional drilling assemblies and methods of forming same
摘要 Reinforced directional drilling assemblies and methods of forming reinforced directional drilling assemblies are provided. Strengthening materials may be incorporated into a resilient layer and/or a polymer-based composite material within a directional drilling assembly to improve the durability and performance of a power section within the directional drilling assembly. Inclusion of strengthening materials within a directional drilling assembly may provide a method to detect the status of a power section and send a signal from downhole upon detecting status of the power section. Inclusion of strengthening materials also may provide a method to collect data about operating conditions, including pressure, temperature, torque, RPM, stress level, shock, vibration, downhole weight on bit, and/or equivalent circulating density to send to the surface or to MWD/LWD systems. The strengthening materials may collect data by themselves or in conjunction with a sensor.
