Influence of installation coordinates of pressure measurement devices in the oil pipeline on accuracy in determining leak parameters

Abstract

The author proposes the method for determining leak coordinate and mass rate. The method is based on the analysis of indications of pressure gages located at the beginning and the end of a pipe, and along the pipeline. The paper describes the formulas for calculating leak coordinate and mass rate according to the offered modified method of hydraulic location. The experimental studies of the method and the rated formulas were carried out on the pipeline for pumping summer diesel fuel. The paper demonstrates the possibility of practical application of the described formulas on the offered method for determining leak parameters on the main pipelines. When analyzing the experimental results the author determined the dependences of calculation errors of leak coordinates and mass rate on location of pressure measurement devices in the pipeline.
