Systems and Methods for estimating forces in a drill bit Drilling

摘要

The methods described include systems and Methods for estimating forces experienced in a Real Time Drilling drill bit and drill disconnect disturbance Force. The Forces of Drill in real time can be estimated on the basis of Observers using measurements of force of drill bit Adapters Sensors at the bottom of the well.The Adopted Model adapted observers estimate the drill forces from measurements of Adapters of Sensors at the bottom of the well. The measurements of tension and torsion as measured by sensor Adaptors are used to estimate the force of drill bit and drill torque.These Measurements can be observed using an effective Observer design with the force of drill bit and drill torque estimated according to Measurements of dual sensor to track the torsion force of drill bit and drill.You can use observations of Forces estimated disturbance force and drill bit identified for Dynamics modeling of drilling and drilling to identify the emergence of negative events.
