Scientists from Perm Polytechnic University (PNIPU) have developed a method for predicting hydrate formation in oil wells.
During the development of oil and gas fields, deposits – hydrates – form in the wells, which clog the equipment and reduce the flow rate.
Specialists from PNIPU have developed a methodology for predicting intervals of hydrate formation under conditions of constant and periodic operation of electric submersible pumps. The method proposed by scientists makes it possible to predict the depth of the onset of deposition with an accuracy of up to 90%
During the analysis, we identified parameters that affect the intensity of hydrate formation: a high gas factor, pressure at the intake of electric submersible pumps below the saturation pressure, and high water cut of oil.
Earlier www1.ru reported that KFU scientists have created effective inhibitors — substances that slow down chemical reactions. They will help prevent the formation of hydrate plugs in gas pipelines and technological systems during oil and gas production and transportation.
