Abstract
Disclosed is a hydrocyclone utilized underground oil-water separation device with power driven rotating blades. A tangent fluid inlet runs through the wall of an oil-string casing to be communicated with a pay zone. The top end of a centre output oil pipe extends out of a hydrocyclone, and an oil outlet is arranged above an oil reservoir packer and communicated with a sucking chamber of an oil extraction pump. The hydrocyclone, the rotating blades and the centre output oil pipe are arranged coaxially. A water injection hole communicated with a water injection target stratum is formed in the wall of the oil-string casing between an oil-water layer packer and a water layer packer. A lower cone of the hydrocyclone is communicated with a cyclone water outlet pipe, and outflow water of the cyclone water outlet pipe is pressured by an underground water-injection sand breaking pump assembly and then is injected into the water injection target stratum through the water injection hole via a water distributor. Before being extracted out of an oil well, oil of the oil reservoir is subjected to oil-water separation underground in advance; separated water is injected to the water injection target stratum directly, and residual oil with low water content is extracted out of the oil well; thus oil production cost is reduced greatly.
