Typical Pressure Drop Calculation Formula for the Applicability of the Pressure Drop of Gelled Crude Oil Hydraulic Suspension Transportation

Abstract

Abstract-The pressure drop is the main parameter which influences the safe operation of the gelled crude oil hydraulic suspension transportation system. According to the current specification for design of oil and gas gathering and transferring rules three types of frictional resistance coefficient calculation model (Colebrook formula, Isaev formula and Atlas Schur formula), contrast and analyse the pressure drop values measured in gelled crude oil hydraulic suspension transportation and calculated with the model. The results show that the pressure drop calculated with Colebrook, Isaev and Atlas Schur formulas error exceeding 71%, and they are not suitable for pressure drop calculation of gelled crude oil hydraulic suspension transportation. So new methods for pressure drop calculation should be found .
