Advanced Model for the Prediction of Tubular Shear Mechanics

摘要

Blow out preventer(BOP)manufacturers have conducted research and development for many years on how shear rams can shear drillpipe,casing and other tubulars passing through the BOP as a well is drilled. In this paper,a significant volume of data on the ability to successfully shear tubular goods is examined. Next,the commonly used and deterministically-based predictive equations for tubular shearing are re-examined and a probabilistic predictive model calibrated on a large test dataset is presented.
