Abstract
The utility model discloses an underground oil-water separated type water injection oil production device, which belongs to oil production equipment. The utility model can solve the difficult problems large water content of liquid for water injection oil displacement and lift, and high oil production cost of non-flowing oil wells. The utility model has the technical proposal that a coaxial oil-water booster pump 9 is arranged below a submersible motor 6; the lower part of the oil-water booster pump 9 is connected with a spiral flow type oil-water separator 11 which is provided with an oil discharge pipe 12 connected with an oil well pump, and a water discharge pipe 13 with a check valve 14 for the water. The utility model has the advantages of simple and compact structure and good oil-water separation, can greatly reduce the oil production cost, and is suitable for use in the non-flowing oil wells.
Description
The utility model provides a kind of underground oil-water separate type water flood recovery device, and it belongs to oil exploration equipment, is used for the oil exploitation of non-whale.
In the oil exploitation process, the blowing time of oil well only accounts for the sub-fraction of whole recovery process.After can not blowing, recover the oil with regard to the method that needs artificial lift because strata pressure reduces.Produce the later stage along with oil well enters, strata pressure continues to descend.When strata pressure is not enough to order about oil and enters well, just need the method displacement of reservoir oil with water filling.Like this, just made and contained a large amount of water in the lifting liquid, have unexpectedly up to more than 90%.At this moment, in order to improve oil well output, the common practice is to adopt the large discharge pump oil pumping on the one hand, then needs on the other hand the water that exploitation comes up is recycled into the stratum again.Circulation has caused a large amount of energy wastes and so forth, makes cost of winning rise greatly.
The purpose of this utility model is a kind of underground oil-water separate type water flood recovery device that can carry out water-oil separating in the shaft bottom of design.
Technical characterictic of the present utility model is that shaft coupling 7 is connected with a profit booster pump 9 under the warp of the lower end of the submersible electric motor 6 of traditional extracting device of oil, the other end of profit booster pump 9 has been installed a funnelform oil water separator 11, water discharge pipe 13 is arranged at oil water separator 11 bottoms, there is oily discharge pipe 12 centre, utilize the cross over pipe 15 between the intake 4 that connects oily discharge pipe 12 and oil well pump 3 that the fluid in the middle of the oil water separator 11 is transported in the oil well pump 3, supercharging enters oil pipe 20 through outlet opening 2 and gives rise to ground.
Structure of the present utility model is such, a kind of underground oil-water separate type water flood recovery device, submersible electric motor 6 by band power transmission cable 1, the oil well pump 3 of the band outlet opening 2 that is connected with submersible electric motor 6 through upper coupling 5 is formed, the main shaft connection that the bottom that it is characterized in that submersible electric motor 6 has following shaft coupling 7 and top to have the profit booster pump 9 of inlet valve 8 connects to form the profit booster body, the bottom of profit booster 9 has one-level spiral-flow type oil water separator 11 at least, top one side of oil water separator 11 has with the outlet opening 10 of the tangent inlet of cylindrical inner surface 22 with profit booster 9 and links, cylinder central authorities have an oily discharge pipe 12 to link through the intake 4 of cross over pipe 15 with oil well pump 3, and there is the water discharge pipe 13 of band one way valve 14 in funnel-form oil water separator 11 central authorities in bottom.
The utility model operating principle is to utilize the profit booster pump that oil-water mixture is sent in the oil water separator from inlet, liquid produces rotation in oil water separator, centrifugal force is discharged from sinking along inwall moisture from water discharge pipe, fluid accumulates in oil water separator central authorities and is inhaled into from oily discharge pipe 12 that supercharging is lifted to ground in the oil well pump.During use, this device and oil pipe 20 be fixed together deliver to producing horizon along oil well casing, use, lower packet delivers to producing horizon with itself and oil well casing, use, lower packet fixes itself and oil well casing, starting submersible electric motor is recverable oil.Isolated water directly injects the water filling layer of lower floor.
The utility model has the advantages that in the down-hole directly and can carry out water-oil separating, the fluid water content of extraction is little, has saved the energy consumption of oil recovery and water filling greatly, to reducing cost of crude oil production unusual effect is arranged.
