Abstract

Technogenic hydrates are mostly a negative factor in the oil and gas industry. Their formation in the bottomhole well zone and in wellbores complicates the extraction, reducing their production rate. In the hydrocarbons collection systems, the hydrates in certain thermobaric conditions deposit on the gas pipeline walls and raise their hydraulic resistance, thus increasing energy costs. The presence of hydrates in the streams of the fluid, extracted from subsoil, increases the wear of production headers, reducing their resource. In the systems of field treatment of hydrocarbons, hydratation negatively affects the technological processes. Hydrate formation in machinery and aggregates of gathering facilities and processing systems leads to accidents. Hydrate deposition in gas pipelines decreases work efficiency. For solving the problems related to prevention and elimination of technogenic hydrates, it is necessary to be able to define the basic parameters of hydrate formation and dissociation. This article is devoted to the research of the processes of formation and dissociation of hydrates. The research was performed using the physical and mathematical models, published in several works, from which it is possible to calculate the main parameters of hydrate formation and dissociation in a wide range of thermobaric conditions. The most widespread conditions of formation and dissociation of hydrates in the development and exploitation of gas and condensate fields were analyzed in this article
