A series of experiments has been conducted to establish laws of gas hydrates creation using process intensifiers - active mixing of water-gas mixture in the reactor, using surfactants, electric field appliance and ultrasound. The methodology of gas hydrate formation intensification from gaseous mixtures of various content has been developed; phase transitions laws have been analyzed during gas hydrate formation considering influence of various physical fields. Mathematical model is developed for the complex understanding of various factors on thermobaric state of gas-vapor bulbs in the time of its oscillation in water. Another mathematical model has been developed for the forced conservation of hydrate samples by an ice coating (upper layer cementation). It has been developed and proposed the new method of gas hydrate blocks creation conserved by an ice layer. Areas with potential gaseous hoist rocks have been identified. Bedding of basic gas-production clays enriched with organic carbon is predicted in the Western, Central and Eastern troughs of Black Sea and in the Sorokin's cavity. Experimental-calculation procedure is proposed for the estimation of the wellbore critical ruining during gas deposits hydrate drilling having closed (external or internal) fracture. Another experimental-calculation procedure is proposed for the critical ruining conditions evaluation during lifting operations of longly exploited drill pipes having external or internal circle fracture.5481 Product Description popup.authors Витязь Олег Юлійович Зоценко Микола Леонідович Клименко Василь Васильович Максимова Елла Олександрівна Овецький Сергій Олександрович Овчинніков Микола Павлович Павленко Анатолій Михайлович Педченко Михайло Михайлович Сай Катерина Сергіївна Свєткіна Олена Юріївна popup.nrat_date 2020-04-02 Close
