Description
Technical field：
It is specifically a kind of to be used for displacement of reservoir oil nano nickel catalyst the present invention relates to catalyst technical field.
Background technology：
Early in 1986, Canadian scholar Hyne found that oil sands bitumen can be split under conditions of steam injection is simulated
Solution reaction, can reduce the content of heavy component, irreversibly reduce the viscosity of viscous crude, be referred to as aquathermolysis
(Aquathermolysis).According to this discovery, domestic scholars, which are contemplated, carries out downhole catalytic reforming viscous crude, mainly pass through to
Oil reservoir adds appropriate catalyst and auxiliary agent, deepens the degree for the aquathermolysis that viscous crude occurs under EOR Conditions, can not
Viscosity of thickened oil is reduced inversely.
Nano material has unique crystal structure and surface characteristic, its catalytic activity and selectivity, which are much higher than tradition, urges
Agent.With the reduction of nanoparticle particle diameter, surface area gradually increases, and adsorption capacity and catalytic performance also strengthen therewith, this makes
Nanocatalyst can not only control reaction speed, greatly improve reaction efficiency, it might even be possible to make the reaction that cannot be carried out originally
Carry out.
The content of the invention：
An object of the present invention be to provide it is a kind of there is certain catalytic action to viscous crude, heavy group in viscous crude after reaction
Asphalt content is divided to reduce, molecular weight reduces, and viscosity of thickened oil is greatly lowered, and the displacement of reservoir oil of viscous crude part lighting is urged with nano nickel
Agent；The second purpose is to provide the preparation method of the displacement of reservoir oil nano nickel catalyst.
