Description
Technical field
The utility model belongs to oil extraction apparatus field, particularly relates to a kind of alloy wax control instrument of cone porous, is applicable to pumpingh well, flowing well and ground crude oil transportation system.
Background technology
In crude oil, generally all contain wax, there is the oil field that a lot of paraffin contents are very high in China, when oil producing operation, crude oil from the process of subsurface to surface because temperature constantly reduces, wax in crude oil can be separated out and condense on sucker rod and tube wall after temperature reaches wax precipitation point (generally 40 ℃ of left and right), the operation that finally causes pumping stops, and must remove the wax solidifying by " well-flushing " and could continue oil pumping, and clear wax control becomes the important technical links of crude oil production.
The most frequently used method of well-flushing is that heat is washed or paraffin removing with chemical method, this is no doubt effective, but after must stopping oil producing operation and experiencing the drainage period of a couple of days, just can restart the operation of pumping, have the discharge of a large amount of chemical substances simultaneously, have a strong impact on crude oil production efficiency and contaminated environment.
, there is following defect in the wax control instrument of prior art: crude oil can not form and repeatedly erupt jet at wax control instrument, and the wax in crude oil cannot fully contact with wax control alloy, suppresses and to slow down the efficiency that condenses into piece of wax low.
Summary of the invention
The purpose of this utility model is to overcome above-described problem.
The purpose of this utility model is achieved in that a kind of alloy wax control instrument of cone porous, comprises union, outer tube, and union and outer tube are threaded connection, and it is characterized in that: described outer tube inside is provided with metastable alloy porous cone; Before metastable alloy porous cone left end is provided with, hold out against lid, the front lid that holds out against welds with outer tube left end; After metastable alloy porous cone right-hand member is provided with, hold out against lid, after hold out against lid and outer tube right-hand member welding.
Described metastable alloy cone is made small-sized taper, conical surface porous type structure by extraordinary metastable alloy.
Described metastable alloy cone selects a plurality of alloy cones to be used in combination according to different specification size, and the connected mode being used in combination connects for embedding.
Before described, hold out against lid and after to hold out against the material that lid adopts be stainless steel.
Before described, hold out against lid and after to hold out against the material that lid adopts be low-alloy steel.
Before described, hold out against lid and after to hold out against the material that lid adopts be carbon steel.
The utility model has changed area of passage by metastable alloy porous cone, forms eruption jet while making crude oil pass through it, through repeatedly shearing and make its fluidised form form turbulent flow, has prevented separating out and reuniting of paraffin; When the metastable alloy porous cone of a plurality of series connection makes crude oil pass through it, crude oil is formed and repeatedly shears and spray, further strengthened cone tail end position crude oil has been formed to turbulent effect, guaranteed the unimpeded of pipeline, improved crude oil production efficiency, avoided the pollution that heat is washed, chemical well-flushing causes, effectively extended the cycle of wax removal sand removal, promoted the use of and there is good economic and social benefit.
Accompanying drawing explanation
Fig. 1 is mounting structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of the utility model metastable alloy porous cone.
In figure: 1. union; 2. before hold out against lid; 3. outer tube; 4. metastable alloy porous cone; 5. after, hold out against lid.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
An alloy wax control instrument for cone porous, comprises union 1, outer tube 3, and union 1 is threaded connection with outer tube 3, and described outer tube 3 inside are provided with metastable alloy porous cone 4; Before metastable alloy porous cone 4 left ends are provided with, hold out against and cover 2, front hold out against cover 2 with outer tube 3 left ends welding; After metastable alloy porous cone 4 right-hand members are provided with, hold out against and cover 5, after hold out against cover 5 with outer tube 3 right-hand members welding; Described metastable alloy cone 4 is made small-sized taper, conical surface porous type structure by extraordinary metastable alloy; Described metastable alloy cone 4 selects a plurality of alloy cones to be used in combination according to different specification size, and the connected mode being used in combination connects for embedding; Before described, hold out against cover 2 and after hold out against cover 5 employings materials be stainless steel; Before described, hold out against cover 2 and after hold out against cover 5 employings materials be low-alloy steel; Before described, hold out against cover 2 and after hold out against cover 5 employings materials be carbon steel.
During concrete enforcement, crude oil holds out against from afterwards and covers 5 and enter metastable alloy porous cone 4 end sections, from metastable alloy porous cone 4 tail ends, be ejected into outer tube 3 under pressure, along the area of space between metastable alloy porous cone 4 and outer tube 3, upwards flow, then enter oil pumping pipeline by union 3.
The chemical compound of metastable alloy porous cone 4 is (by weight percentage): Ni 5～10, and Cu 50～80, and Sn 2.0～8.0, and P 3.0～10.0, and Re 0.5～1.0, and wherein Re is rare earth element, is selected from Y and Gd one or a combination set of; Metastable alloy porous cone 4 tail end positions form eruption jet by changing when area of passage makes crude oil pass through it, through repeatedly shearing and make its fluidised form to form turbulent flow, to reach, prevent separating out and reuniting of paraffin; 4 series connection of metastable alloy porous cone form and repeatedly shear and spray crude oil while making crude oil pass through it, further strengthened cone tail end position crude oil is formed to turbulent effect; Crude oil forms turbulent flow and fully contacts with metastable alloy porous cone 4 surface courses; By electrochemical action, change the reunion behavior of wax electronic structure of molecule and then change wax crystalline substance, effectively suppress and slow down the piece that condenses into of wax, impel the wax of separating out to float on a liquid with small crystal habit and with liquid flow, therefore effectively prevent and delay wax condensing on tube wall, sucker rod, thereby extending the clean-out service cycle of oil well.
