METHOD FOR TRANSPORTING OIL WITH A HIGH GOR USING A CONTROLLED HYDRATE FLOW Russian patent published in 2021 - IPC C10L3/06 C10L3/10 F25J1/00 F17D3/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas industry and can be used in the production and transportation of oil with a high gas ratio without degassing by intentionally obtaining gas hydrates and creating a controlled flow of hydrate-containing oil. The invention relates to a method for transporting oil with a high gas ratio using a controlled hydrate flow, in which the equilibrium condition of hydrate formation is calculated using a computer program; the calculated equilibrium condition of hydrate formation is compared with the condition for transporting oil with a high gas-oil ratio; select the degree of temperature shift required to expand the stability region of the hydrate along the entire gradient of P, T-conditions for oil transportation; a suitable thermodynamic promoter of hydrate formation is selected, including its concentration for the selected degree of temperature shift; a selected thermodynamic hydrate formation promoter is added to shift the equilibrium temperature; a kinetic hydrate promoter is added to accelerate the formation of gas hydrates; if necessary, an anti-agglomerant is added to prevent agglomeration of the hydrate particles.

EFFECT: control of hydrate formation by selecting the optimal concentrations of reagents to ensure the stability of hydrates and a safe mode of oil transportation.
