USE DENSITY COEFFICIENT APPROACH TO CALCULATE SUSPENSION LOAD AT POLISHED ROD HANGER

    Graphical Abstract
    • Abstract
  • Based on the comprehensive analyses of previous suspension load calculation methods at polished rod hanger, the paper presents a new one named density correlation coefficient approach under the conditions to ensure calculation accuracy and simplify calculating procedures. The theoretical analysis, formula deduction and practical calculation procedures are also presented. Good results were obtained in fields use.
