Description
Technical field
The utility model relates to the integrated oil well pump of a kind of super viscous crude steam injection oil recovery, is applicable to the exploitation of unitized production viscosity super thick oil well more than 50000mPa.s of steam soak thermal recovery and other heating, viscosity reducing measures.
Background technique
Under formation condition, viscosity is called super viscous crude greater than the crude oil of 50000mPa.s.Super viscous crude viscosity of crude is high, does not substantially flow, and can't exploit with conventional oil production technology.Because super viscosity of thickened oil is high especially, can not enter oil well pump with the method crude oil that heats on pump; Poor with crude oil fluidity on the method pump that heats under pump, efficient is low, and causes sucker rod roofbolt surface friction drag large, causes bending, disconnected takes off, the rod and tube partial-wear aggravation.Therefore need to mix on the steam soak proportioning pump under pump on hot water or pump the viscosity reducing measure such as electric cable heating and comprehensively reduce viscosity of crude, with super heavy oil recovery out.
At present, the most frequently used oil well pump is super heavy oil injecting-mining oil well pump, and its steam injection passage is the fluting on pump barrel, adopts long-plunger to coordinate with the pump barrel of fluting.But, in order to increase economic efficiency, needing as early as possible with the oil extraction after viscosity reduction out after having annotated steam, this just needs the long super heavy oil injecting-mining oil well pump of the large stroke of diameter.And long heavy oversize cannot the processing of long column setier of diameter big-length.Therefore former super heavy oil injecting-mining oil well pump cannot be realized the requirement of large pump long stroke, therefore can not satisfy the technique needs of exploiting super viscous crude more economically.
Summary of the invention
The purpose of this utility model be to provide that a kind of major diameter long stroke is suitable for the unitized production viscosity of steam soak thermal recovery and other heating, viscosity reducing measures super viscous crude is used more than 50000mPa.s extraordinary tubing pump.
the utility model is by the connecting-and-unconnecting device assembly, sealing locking assembly, the pump barrel assembly, plunger piston assembly, the standing valve assembly forms, its sealing locking assembly top is connected with hollow rod by the connecting-and-unconnecting device assembly, sealing locking assembly bottom is connected with plunger piston assembly by hollow connecting rod, the bottom of the plunger lower contact of plunger piston assembly has a groove and two spiral jaw chucks, push rod and the cross bar that a cross is connected is equipped with on the top of standing valve assembly, the upper-end surface of pump barrel assembly support ring has a conical surface that matches with the seal ring of sealing locking assembly, the lower end surface of pump barrel assembly support ring have one with and the conical surface that matches of the claw of sealing locking assembly.during steam injection, first transfer hollow rod, drive the connecting-and-unconnecting device assembly, seal assembly, plunger piston assembly is descending, form when sealing when walking to the seal ring that the makes sealing locking assembly conical surface with the upper-end surface of pump barrel assembly support ring, the claw spreading of sealing locking assembly and with the support ring lower end surface locking of pump barrel assembly, the push rod of standing valve assembly this moment upper end backs down the valve ball that moves about of plunger piston assembly, the cross bar of standing valve assembly enters in plunger lower contact groove, two spiral jaw chucks of plunger lower contact enter the standing valve assembly and fixed valve ball are picked up, then rotate hollow rod, because the cross bar of standing valve assembly enters in plunger lower contact groove, the rotation hollow rod can make the upper body of connecting-and-unconnecting device assembly and lower body throw off, reintroduce the upper body of hollow rod and connecting-and-unconnecting device assembly, steam is locked the assembly endoporus by sealing, the hollow connecting rod endoporus, the plunger endoporus, oil reservoir under standing valve assembly endoporus injection pump.Turn when taking out when having annotated steam, first transfer the upper body of hollow rod and connecting-and-unconnecting device assembly, deadweight docking connecting-and-unconnecting device assembly by hollow rod and connecting-and-unconnecting device assembly upper body, then go up exhaust heart sucker rod, assembly is locked in drive connecting-and-unconnecting device assembly, sealing, plunger piston assembly is up, the claw of sealing locking assembly and the support ring of pump barrel assembly are thrown off, and move about this moment valve ball and fixed valve ball automatically reset, and oil well pump can normally be pumped.Due to the connecting-and-unconnecting device assembly being arranged between oil well pump and hollow rod, can realize that steam injection again turns to take out, and can realize oozing on pump hot water technique and electrical heating process.
The utility model reasonable and compact in structure is united viscosity reduction together with can realizing the big pump diameter oil well pump and mixing the viscosity reducing measures such as hot water or electric cable heating on heat extraction by steam injection and pump, and high-efficiency mining viscosity is higher than the super viscous crude of 50000mPa.s.
