Abstract

Deposits of solid gas hydrates in gas and gas-oil wells at the late stages of field development is one of the most common types of well complications. The formation of hydrate deposits in the well leads to clogging of the flow area of the lifting pipes, a decrease in well productivity, abrasive wear of the working bodies of the pumps and product emulsification. Methods for removing hydrate plugs are very expensive, and their effectiveness is low due to their recurrence. One of the most promising methods of dealing with hydrate deposits is a preventive method, which consists in maintaining thermobaric conditions in the well, under which hydrates will not form. This technique is proposed to be implemented using the Katz technique for determining the sum of molar components in the gas phase.
