Abstract
The utility model relates to a combined sucker rod which is a working part of a lifting oil production system of an oil field and an oil well and is connected with an oil pumping unit and a reciprocating oil well pump. The carbon steel or alloy steel rod section of the combined sucker rod are butted with the composite material rod section of carbon fiber or glass fiber reinforced plastic and carbon fiber or glass fiber reinforced plastic; or the carbon steel or alloy steel rod segment is butted with the composite material rope of carbon fiber or glass fiber reinforced plastics and carbon fiber or glass fiber reinforced plastics. Thus, the resistance which needs to be overcome by the combined sucker rod for lifting the reciprocating oil well pump is greatly reduced; useless power consumption can be reduced. Accordingly, the speed of lifting the sucker rod can be enhanced and the work efficiency and the oil extraction yield of the lifting oil extraction system can be enhanced.
Description
The utility model relates to the workpiece that a kind of oilfield promotes oil extraction system, is the sucker rod that connects oil pumper and reciprocating oil pump.
The later stage of the well recovery in oil field is to adopt the reciprocating oil pump oil pumping, and the dynamic power machine of its oil pumping is the oil pumper that the rotary power of motor is converted into the reciprocal lifting power of low speed on aboveground ground.Because oil well is all deep, the transmission between oil pumper and the reciprocating oil pump is very long sucker rod.Traditional in the past sucker rod all is the carbon steel or the alloy steel pole section of screw thread butt joint.How dark well have, and how long sucker rod will have.This has just caused oil pumper in order to drive reciprocating oil pump, and must drive very heavy sucker rod.The sucker rod of an oil well on average is ten tons of weights, and what have reaches more than 20 ton.Oil pumper will be added with counterweight for this reason, but still reciprocating motion is very uneven, and impact is very big.When oil well pump was descending, very heavy sucker rod will impact the oil pumper motion on the contrary.Sucker rod has consumed the power consumption of significant proportion, has caused waste.Main is to make that the speed that promotes oil pumping is very slow, has influenced the operating efficiency that promotes oil extraction system widely, and the output that the lifting oil extraction system is recovered the oil is very low.In order to improve the oil recovery amount that promotes oil extraction system, people are not finding effective way and structure always.
For this reason, the purpose of this utility model provides and a kind ofly oil pumper is moved back and forth tend to balance, to reduce the oil pumper power consumption, to improve the sucker rod that promotes rate of pumping and promote the oil extraction system operating efficiency.
Sucker rod of the present utility model still has the carbon steel or the alloy steel pole section of screw thread butt joint.Its design feature is: carbon steel or alloy steel pole section are also to being connected to carbon fiber or glass fiber reinforced plastic and carbon fiber or glass fiber reinforced plastics composite material bar section; Perhaps carbon steel or alloy steel pole section are also to being connected to carbon fiber or glass fiber reinforced plastic and carbon fiber or glass fiber reinforced plastics composite material rope.
Like this with the carbon fiber of light-high-strength or glass fiber reinforced plastic and carbon fiber or glass fiber reinforced plastics composite material bar section and rope a part as sucker rod, the sucker rod of the multi-section multi-layer that the bar section of employing unlike material, different specific weight forms, can reduce the weight of sucker rod widely, significantly reduce oil pumper and promoted the resistance that reciprocating oil pump will overcome, reduced useless power consumption, thereby improved the speed that promotes oil pumping, improved the operating efficiency and the oil recovery amount that promote oil extraction system.
In order to guarantee to promote the descending speed of oil extraction system, overcome descending mechanical friction resistance effectively, the carbon steel or the alloy steel pole section of one section screw thread butt joint also will be arranged.The size that the carbon steel of screw thread butt joint or alloy steel pole segment length depend on running resistance.Carbon steel or alloy steel pole section are docked with carbon fiber or glass fiber reinforced plastic and carbon fiber or glass fiber reinforced plastics composite material bar section, and perhaps carbon steel or alloy steel pole section preferably also are to take the screw thread butt joint with docking of carbon fiber or glass fiber reinforced plastic and carbon fiber or glass fiber reinforced plastics composite material rope.For the ease of installation, the carbon fiber of butt joint or glass fiber reinforced plastic and carbon fiber or glass fiber reinforced plastics composite material bar section are also preferably in segmentation, and the carbon fiber of segmentation or glass fiber reinforced plastic and carbon fiber or glass fiber reinforced plastics composite material bar section also are to dock with screw thread.
Accompanying drawing has been represented two kinds of knockdown sucker rod structural representations of the utility model.Wherein, Fig. 1 is a rigid body combined type sucker rod schematic diagram, and Fig. 2 is a rigid and flexible body combined type sucker rod schematic diagram.Example below in conjunction with accompanying drawing further specifies the utility model.
The bottom of embodiment 1, rigid body combined type sucker rod is the carbon steel bar section 1 of screw thread butt joint.The top of rigid body combined type sucker rod is carbon fiber or fiberglass rod section 3, just more than the carbon steel bar section also to being connected to carbon fiber or fiberglass rod section.Carbon steel bar section adopts screw thread butt joint 2 with docking of carbon fiber or fiberglass rod section.Deep as oil well, carbon fiber or fiberglass rod section are long, and carbon fiber or fiberglass rod Duan Yingzai are divided into several sections, between each section also with being threaded.The proportion of carbon fiber or fiberglass rod is 1/10th of carbon steel or alloy steel pole section, and former average ten tons of heavy sucker rods can be relieved to nearly one ton of weight, can make the hoisting velocity that promotes oil extraction system double many.The common driving of nearly one ton gravity and oil pumper is arranged when descending, and speed is almost constant.So, adopted the deep-well of this rigid body combined type sucker rod to promote the oil recovery amount that oil extraction system can double, can also reduce the energy consumption of part drive motors.
Embodiment 2, rigid and flexible body combined type sucker rod, its underpart are alloy steel pole section 4, and epimere is a carbon fibre composite rope 6.Just more than the alloy steel pole section also to being connected to the carbon fibre composite rope.Alloy steel pole section adopts the screw thread butt joint with docking of carbon fibre composite rope.Carbon fibre composite rope lower end is the carbon fiber bolt 7 of rigidity, is connected with the screw of alloy steel pole section upper end.Descending resistance ratios as oil pumper is bigger, and alloy steel pole section requires long, and alloy steel pole Duan Yingzai is divided into several sections, between each section also with being threaded.The proportion of carbon fibre composite rope is 1/10th of carbon steel or alloy steel pole section, former 20 tons of heavier heavy sucker rods can be relieved to two tons multiple, can make the hoisting velocity that promotes oil extraction system double many.The lifting oil extraction system only overcomes the mechanical friction resistance of oil well pump when descending, and the not anti-oil pumper that drives, the gravity more than two tons can make equally and promote the descending speed maintenance of oil extraction system near original speed.So just make that the oil pumper operating ratio is more steady, significantly reduced useless power consumption, can make the efficient of oil pumping improve nearly one times.
