Abstract
The utility model provides a double-pump joint-operation heavy oil recovery device which is reasonable and practical in structure and high in recovery efficiency. According to the technical scheme, a hollow sucker rod (1) is connected with a solid plunger (5) through a check valve (4), the solid plunger (5) is connected with a connecting rod (6) through screw threads, the connecting rod (6) is connected with an oil well pump (10) through screw threads, the wall of a screen pipe (7) and the wall of an oil pipe (2) are connected through screw threads, a horn mouth (11) is connected with the oil pipe (2) through screw threads, an artificial well bottom (12) is arranged under the horn mouth (11), a first packer (8) and a second packer (9) are connected with the wall of a sleeve (3) through screw threads, and an automatic control system (13) is installed on the wall opposite to a heating device (14). The double-pump joint-operation heavy oil recovery device is reasonable and practical in design; viscous resistance to operation of the sucker rod is reduced, and therefore the sucker rod will not go down slowly; the lifting effect is improved; the double-pump joint-operation heavy oil recovery device has the advantages of reducing energy consumption and cost, being safe and convenient to use and suitable for being popularized and used generally and the like.
Description
Technical field
The utility model relates to oil drilling equipment technical field, and especially double pump connection is made device for producing thickened oil.
Background technology
At present, oil drilling device for producing thickened oil complex structure is loaded down with trivial details, and production efficiency is low, moreover is often to break down, and maintenance and inconvenience thereof, waste time and energy.In thickened oil recovery, conventional well wellbore lifting technology is to adopt electric heating rod, admixture hot water, interpolation chemical agent etc., but in application, all there is certain defect at the scene, intensification viscosity reduction output metering mixed with hot water is inaccurate, chemical viscosity reduction, electrical heating have pollution, energy consumption is large, and cost for oil production Gao，Gei enterprise brings economic loss.
Summary of the invention
The purpose of this utility model is to provide a kind of practicality rational in infrastructure, the double pump connection that production efficiency is high is made device for producing thickened oil, its technical scheme is: hollow rod is connected with solid plunger by ball-and-seat, solid plunger is connected with connecting rod screw thread, connecting rod is connected with oil well pump screw thread, screen casing is connected with oil pipe tube wall screw thread, horn mouth is connected with oil pipe thread, under bell-mouthed, be provided with artificial bottom of a well, the first packer is connected with sleeve pipe tube wall screw thread with the second packer, on the wall on heater opposite, automatic control system is installed.What the first packer adopted is connect+Y111-150 of peace packer; What the second packer adopted is connect+Y211-150 of peace packer.
The utility model practicality reasonable in design, reduced sucker rod operation viscosity resistance, realized sucker rod slow under, improved lifting effect, there is the energy consumption of reduction and cost, the advantage such as safe and convenient to use, is applicable to generally promoting the use of.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
The specific embodiment
As shown in the figure, double pump connection is made device for producing thickened oil, mainly hollow rod 1, oil pipe 2, sleeve pipe 3, ball-and-seat 4, solid plunger 5, connecting rod 6, screen casing 7, the first packer 8, the second packer 9, oil well pump 10, the second aviation plug 11, artificial bottom of a well 12 and automatic control system 13, consists of; Hollow rod 1 is connected with solid plunger 5 by ball-and-seat 4, solid plunger 5 is connected with connecting rod 6 screw threads, connecting rod 6 is connected with oil well pump 10 screw threads, screen casing 7 is connected with oil pipe 2 tube wall screw threads, horn mouth 11 is connected with oil pipe 2 screw threads, under horn mouth 11, be provided with artificial bottom of a well 12, the first packers 8 and be connected with sleeve pipe 3 tube wall screw threads with the second packer 9, automatic control system 13 is installed on the wall on heater 14 opposites.What the first packer 8 adopted is connect+Y111-150 of peace packer; What the second packer 9 adopted is connect+Y211-150 of peace packer.
The utility model workflow: during tubing string work, have two parts fluid to flow, oil pipe and hollow stem fluid are conduction oil, and oil jacket annular space is from oil well produced liquid.Conduction oil is heated to 150-220 ℃ of left and right by heater, is pumped in hollow rod, then by circulating valve, conduction oil is discharged in oil pipe by circulation pump, flows out well head enter and in heater, heat sealing and circulating by oil pipe.Produced Liquid is extracted into oil pipe by oil extraction pump, and by double pump continuous cropping device, by screen casing, to be discharged to oil jacket annular space up, by sleeve valve, enters petroleum pipeline.Whole process two fluids take their own roads, mixed flow not mutually.
