Research on the Correction Method for Measurement Data of WOB while Drilling Based on Strain Analysis

Abstract:

By detecting the axial strain at the near-bit, we can obtain the weight on bit(WOB), however, some other factors in the well such as hydrostatic force, circulating pressure, may also affect the measurement. Unless take these factors into consideration, derive the correction formula for the measurement data of WOB, eliminate the impact of other forces, we may not obtain the actual data of the weight on bit.
