METHOD OF DETERMINATION OF PIPE STRING LENGTH IN ROUND TRIP OPERATIONS IN WELL Russian patent published in 2003 - IPC

Abstract RU 2211921 C1

FIELD: oil and gas producing industry; applicable in determination of pipe string length. SUBSTANCE: method includes determination of pipe string length by summation of length of each pipe. Length of each pipe is determined by measuring its weight on hook of load-lifting plant and division of obtained weight by weight of running meter of this pipe. Value of running meter weight of each pipe is stored in controller memory. EFFECT: indirect determination of pipe string length with high accuracy without use of means for measuring length. 1 dwg
