Estimate the junction temperature by the temperature sensitive electrical parameter method, set the space thermal model of the extended state, and apply the Kalman filter to the junction temperature estimation.

Abstract: A system and method for acoustically profiling a wellbore while drilling, and which identifies depths in the wellbore where the wellbore diameter is enlarged or has highly fractured sidewalls. These depths are identified based on monitoring either travel time or signal strength of acoustic signals that propagate axially in the wellbore. Correlating wellbore depth to travel time of a signal traveling downhole inside of a drill string and uphole outside of the drill string yields an average signal velocity in the wellbore. Depths having a lower average signal velocity indicate where the wellbore diameter is enlarged or has highly fractured sidewalls. These depths are also identified by generating separate acoustic signals inside and outside of the drill string, comparing signal strengths of signals reflected from the wellbore bottom, and identifying the depths based on where there is an offset in the strengths of the reflected signals.

Abstract: Conventional practice for determining a life expectancy of a drilling tool has been based on simple static bending moment evaluation and/or conservative past experience life limits. This archaic practice has often led to premature scrapping of the tools and has proven to be overly conservative and cost-ineffective. Introduced herein is a BHA condition monitoring technique that combines both field data and advanced models in one system. The introduced technique is based on a combination of system and component level models to monitor and evaluate the current health and life of BHA components. The introduced technique can apply to all directional drilling BHAs, including mud motors and rotary steerable systems, and can be used at different levels of the tool's life cycle to improve efficiency, reduce downhole failure incidents, and maximize assets' utilization.
