Embodiment 1

[0027] Mix 3 volumes of crude oil and 1 volume of water, and add oπ-10 (alkylphenol polyoxyethylene ether) whose mass is 1% mass concentration of the water amount and span60 whose mass is 2% mass concentration of the water amount, and stir well to make It forms a stable emulsion. Then take 10ml of the emulsion and add it into a transparent sapphire kettle with a magnetic stirring bar. Then put the sapphire kettle into the air bath, connect the pipeline to evacuate, drain the air in the kettle, and then fill it with the composition of "CH 4 97%+C 2 h 6 2.5%+C 3 h 8 0.5%" of natural gas (simulated natural gas) to make the pressure reach 7MPa. Start the magnetic stirring, and set the temperature of the air bath to 4°C. With the formation of hydrate, the pressure in the kettle will decrease, and the piston will be moved upward by the manual pump to make The natural gas pressure is basically constant, and the amount of gas reacted and its relationship with the reaction time (r...

Embodiment 2

[0030] Adjust the oil-water mixing volume ratio to 2:1, and other operating steps are the same as in Example 1.

Embodiment 3

[0032] Adjust the oil-water mixing volume ratio to 1:1, and other operating steps are the same as in Example 1.

Abstract

A method for storing and / or transporting oil - gas in solid state mixture includes mixing water with oil product to form emulsion , contacting formed emulsion with natural gas for forming natural gas to be hydrate in oil product and water to obtain hydrate oil liquid , controlling temperature of said hydrate oil liquid at temperature of minus 1 to minus 15 deg.c for making it be solidified in order to store and / or transport oil - gas in its solidified state under constant pressure or low pressure .

Description

technical field [0001] The invention relates to a method for storing and / or transporting natural gas, in particular to a method for solid-state mixed storage and / or transport of oil-gas realized by utilizing hydrate technology, and belongs to the field of oil and gas storage and transport. Background technique [0002] Hydrates are small molecular gases (N 2 , CO 2 , CH 4 , C 2 h 6 , C 3 h 8 etc.) and water at a certain temperature and pressure to form a crystalline substance. The formation temperature of hydrates is generally between 0°C and 15°C, and the formation pressure varies greatly with the gas forming hydrates. In recent years, natural gas hydrate has attracted more and more attention from the international energy community, and many large-scale international conferences have been held to discuss the development prospects of natural gas hydrate as a potential new energy and new technology development (solid-state transportation, storage, environmental protect...
