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.

主权项

1. A reinforced drilling assembly comprising:
at least one component with at least one strengthening material applied to a portion of at least one resilient layer to form at least one reinforced resilient layer, the at least one component having multiple axial sections with strengthening materials differing between at least two of the multiple axial sections; and a reinforced polymer composite adhered to the at least one reinforced resilient layer.
