METHOD FOR PREVENTION OF HYDRATE FORMATION AT DEVELOPMENT OF GAS FIELDS AND AT TRANSPORTATION OF WELL PRODUCT THROUGH GAS PIPELINE

摘要

Method for prevention of hydrate formation at development of gas fields and at transportation of well product through gas pipeline includes pumping-in to discharge line of the well and to the gas pipeline inhibitor of hydrate-formation. As inhibitor of hydrate-formation one uses 0,05 % solution of surface-active substance in fresh water. The 0,05 % solution of surface-active substance in fresh water is every day uniformly pumped-in to the discharge line of the well and to the gas pipeline in amount from 3,0 to 5,0 m3/day, this is set in those limits depending on the results of observations of the change of pressure gradient in discharge line of the well and the gas pipeline.
