Abstract
The utility model discloses a novel high-pressure plastic spring tube, which relates to wellhead sealing of a pumping unit well in oil exploitation. The sealing structure of an existing pumping polished rod has the shortcomings of easy abrasion, leakage and large energy consumption. The novel high-pressure plastic spring tube is formed by arranging connection sleeves at two ends of a plastic spring telescopic tube, and respectively connecting a lower connection sealing structure and an upper connection sealing structure on the connection sleeves at the two ends of the plastic spring telescopic tube, wherein the plastic spring composite tube is formed by lining a steel wire spring on an inner layer of a plastic tube. By using the high-pressure plastic spring tube, traditional wellhead packing static sealing is converted into an elastic dynamic sealing, and a traditional sealing mode is replaced, thereby the purpose of saving energy is achieved. As the elastic tube is stretched and compressed along with a dip rod and can freely and relatively move, the novel high-pressure plastic spring tube can not apply work or consume electric energy because of the need of overcoming friction between the dip rod and an elastic body.
Description
Technical field
The utility model relates to the well head hermetically-sealed construction of rod-pumped well in a kind of oil exploitation, is exactly a kind of novel high-pressure plastics spring pipe of energy-saving and environmental protection type rod-pumped well well head specifically, is used for leakproof.
Background technology
At present recover the oil and mainly still have the beam type pumping unit of sucker rod in the oil field, this equipment in oil recovery process, in order to prevent the leakage of extraction liquid, employing be the structure of packing_seal in conjunction with oil pumping polish rod.Oil pumping polish rod packing_seal in pumping easily is worn and very fast inefficacy, causes leakage.In order to solve the packing filling wearing and tearing, the oil recovery workman must frequently compress or change encapsulant.Therefore, the working strength of workers of recovering the oil on the one hand is big and bring very big inconvenience to oil producing operation; On the other hand, cause the well head leakage to bring environment pollution owing to very easily missing, and, increased the energy consumption of pumping-unit motor owing between packing filling and the oil pumping polish rod very big frictional force is arranged.
The utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the big defective of leakage easy to wear, energy consumption that existing oil pumping polish rod hermetically-sealed construction exists, and the novel high-pressure plastics spring pipe of the energy-saving and environmental protection of a kind of oil pumper well head, leakproof is provided.For this reason, the utility model is by the following technical solutions:
Novel high-pressure plastics spring pipe, it is characterized in that: its two ends at the plastics spring telescoping tube are provided with adapter sleeve, and under connecting respectively on the adapter sleeve at plastics spring telescoping tube two ends, connect hermetically-sealed construction, on connect hermetically-sealed construction and constitute, described plastics spring clad pipe be the internal layer lined steel silk spring formation at plastic pipe.
As preferably, described plastics spring telescoping tube is a helical form.
As preferably, described wire spring cross section be shaped as tabular, and its minor axis direction is consistent with the bearing of trend of described plastic pipe, the position of described wire spring contact plastic pipe is a cambered surface.
As preferably, describedly go up that to connect hermetically-sealed construction be spherical sealing funnel or the sealing device that has male thread.
As preferably, described connection hermetically-sealed construction down is a sealed adapter sleeve.
Described down connection hermetically-sealed construction, on connect hermetically-sealed construction and described plastics spring telescoping tube two ends adapter sleeve by screwed connection together.
The beneficial effects of the utility model are: utilize the high-pressure plastic bourdon tube to transfer traditional well head packing static seal to flexible movable sealing, replaced traditional sealing means, thereby reached purpose of energy saving.Because elastic tube is with beam hanger Compression and Expansion and can free relative motion, therefore can not overcome beam hanger because of need and propose friction and the consumed power that does work with elasticity.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Number in the figure explanation: 1-plastics spring telescoping tube, 2A/2B-adapter sleeve, connection hermetically-sealed construction under the 3-, the last connection of 4-hermetically-sealed construction, 5-plastic pipe, 6-wire spring.
The specific embodiment
Below in conjunction with Figure of description the utility model is described further.
As shown in Figure 1, this novel high-pressure plastics spring pipe is at the two ends of plastics spring telescoping tube 1 adapter sleeve 2A and 2B to be set, and connect under on the adapter sleeve 2A at plastics spring telescoping tube two ends and 2B, being connected respectively hermetically-sealed construction 3, on connect hermetically-sealed construction 4 and constitute, plastics spring clad pipe 1 (referring to Fig. 2) is in plastic pipe 5 internal layer lined steel silk spring 6 formation of (as making with plastics such as PE, PU, TPE or materials such as modifying plastics material and rubber).Further, plastics spring telescoping tube 1 is a helical form; Wire spring 6 cross sections be shaped as tabular, and its minor axis direction (being exactly the less direction of size) is consistent with the bearing of trend of plastic pipe 5 so that the plastics spring telescoping tube has flexible preferably ability, the position of wire spring 6 contact plastic pipes 5 is a cambered surface; Last connection hermetically-sealed construction 4 is spherical sealing funnel or the sealing device that has male thread; Following connection hermetically-sealed construction 3 is a sealed adapter sleeve; Following connection hermetically-sealed construction 3, on connect hermetically-sealed construction 4 and plastics spring telescoping tube 1 two ends adapter sleeve 2A be in the same place by screwed connection with 2B.This novel high-pressure plastics spring pipe, wear-resisting, oil resistant, anti-high pressure (can reach 5MPa), drawing numbers 〉=5,000,000 time back and forth.
This novel high-pressure plastics spring pipe will connect hermetically-sealed construction down during use and be fixed on the polished rod, on connect hermetically-sealed construction and utilize well head wedge support or utilize screwed connection to buckle at the internal thread of wedge.Realize the nothing wearing and tearing of oil pumper well head oil pumping polish rod, oil pumper does not need to overcome the frictional resistance between packing and the oil pumping polish rod and does work; Well head does not have the leakage of extraction liquid fully, thereby when having got lost circulation prevention, has more the meaning of environmental protection and energy saving.
