US 12,760,606 B2 · Determination of tubular connection height above a rig floor

Abstract

A tubular connection position measurement system can include an acoustic transmitter secured with a rotary table, and an acoustic receiver secured with the rotary table. Another tubular connection position measurement system can include an acoustic transmitter, an acoustic receiver, and a controller configured to adjust a position of a tong assembly, based on a transit time of an acoustic signal transmitted in a tubular and received by the acoustic receiver. A method of determining a tubular connection position can include transmitting an acoustic signal through a tubular, a portion of the tubular being positioned above a rig floor, receiving a reflection of the acoustic signal, and determining a height of the portion of the tubular above the rig floor, based on a transit time of the transmitted and reflected acoustic signal through the portion of the tubular.
