Diagnosis of the technological condition of the main gas pipeline according to the composition of the gas

Abstract

The (technological) condition of its inner surface is of great importance among the factors affecting the discharge capacity and hydraulic characteristics of the main gas pipeline. If natural gas is not prepared for transportation at the level of existing technical standards and requirements, the cross-section of the gas pipeline may be reduced or obstructed as a result of the condensation and precipitation of water and light hydrocarbon vapors inside the pipeline. Depending on the topography of the track, various sediments accumulate on the inner surface of the lower parts of the gas pipelines installed in complex geographical conditions and cause negative effects on the operation of the transportation system. The use of component composition of gas as an auxiliary tool, a sign for the diagnosis of various technological processes in oil and gas extraction, as well as for the prediction of transport parameters, has been studied in numerous research works.
