METHOD AND DEVICE FOR RECOVERING OIL

摘要

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.

1. 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.
