Abstract
There is provided a method or a device for recovering oil economically and with little impact on the environment. With the present invention's method and device for recovering oil, a heat-generating means is installed inside one of at least two pipes that are parallelly inserted into the soil (for example, an oil sand stratum or a core stratum). The heat is exerted on the oil contained in the soil so as to reduce the viscosity of oil, which is then recovered via the other pipe. The heat-generating means reacts amphoteric metal or its alloy with an alkaline aqueous solution in the pipe and then combusts the hydrogen generated by the reaction.
Claims21
A method for recovering oil, wherein
- after amphoteric metal or its alloy is filled inside at least one of two pipes that are parallelly inserted into an oil sand stratum, an alkaline aqueous solution is supplied to react with the amphoteric metal or its alloy, and
- both the heat and the hydrogen that are generated by said reaction are exerted on the oil sand stratum so as to separate oil from the oil sand stratum, which oil is then collected and subsequently recovered via the other pipe.
A method for recovering oil, wherein
- after amphoteric metal or its alloy is inserted inside at least one of two pipes that are parallelly inserted into an oil sand stratum, an alkaline aqueous solution is supplied to react with the amphoteric metal or its alloy, and
- the hydrogen generated by this reaction is combusted, and the heat generated by said combustion is exerted on the oil sand stratum so as to separate the oil from the oil sand stratum, which oil is then collected and subsequently recovered via the other pipe.
A device for recovering oil, with said device consisting of
- at least two pipes that are inserted into the soil, one of which pipes is filled with amphoteric metal or its alloy, and
- an alkali tank that stores an alkaline aqueous solution, and
- with the other pipe supplying the alkaline aqueous solution from said alkali tank to said reaction pipe, applying and exerting on said oil the hydrogen and reaction heat that are generated by a reaction of the alkaline aqueous solution and amphoteric metal or its alloy, and then collecting and recovering the resultant flown oil.
A device for recovering oil, with said device consisting of
- at least two pipes that are inserted into said soil, one of which pipes is filled with amphoteric metal or its alloy,
- an alkali tank that stores an alkaline aqueous solution, and
- a combustion means that supplies the alkaline aqueous solution from said alkali tank to said reaction pipe and then combusts hydrogen that is generated by reacting the alkaline aqueous solution with said amphoteric metal or its alloy,
- and with the other pipe applying and exerting on said oil the heat that is generated by said combustion of hydrogen, then collecting and recovering the resultant flown oil that is produced due to the heat generated by said combustion of hydrogen.
