Detailed description of the invention
Below in conjunction with the accompanying drawings vibration wax-proof viscosity reducing oil pipe of the present invention is described in further detail.A kind of vibration Wax-proof viscosity reducing oil pipe includes oil pipe body 3, is arranged with vibrating reed 8, the limit of vibrating reed 8 outside the lower end of oil pipe body 3 Edge is provided with at least one gap 9, and gap 9 includes the first area 91 being arranged in vibrating reed 8, and gap 9 also includes Connecting the second area 92 at the edge of first area 91 and vibrating reed 8, second area 92 is being perpendicular to Big width A is being perpendicular to Breadth Maximum B radially, as shown in Figure 1, Figure 2, Figure 3 shows less than first area 91.
Gap 9 is in the form of a duckbill in the direction being perpendicular to vibrating reed 8 surface, i.e. gap 9 includes being arranged on vibrating reed 8 Interior first area 91, gap 9 also includes the second area 92 connecting the edge of first area 91 and vibrating reed 8, As it is shown on figure 3, split with dotted line between first area 91 and second area 92, first area 91 is arch, and The arc length of this arch is long more than the semicircle of this arch place circle, and second area 92 is rectangle, the maximum of second area 92 Width is less than the Breadth Maximum of first area 91.Being proved by test, this duckbill gap has more preferable water conservancy diversion energy Power, has the effect slowing down sucker rod stress simultaneously, and wax crystalline substance destruction becomes apparent from.First area 91 is for bending Shape or rectangle or triangle.
In the present embodiment, the edge of first area 91 is circular arc, and the central angle corresponding to this circular arc is 270 °~300 °.Second area 92 includes two sides, and two sides are the straight line being parallel to each other, such as Fig. 2 and Fig. 3 Shown in, second area 92 is rectangle.The Breadth Maximum A of second area 92 is less than the Breadth Maximum of first area 91 B.Or, second area 92 includes that two sides, two sides can also be camber line, as shown in Figure 4.
In the present embodiment, the Breadth Maximum of second area 92 is the 1/2~2/3 of first area 91 Breadth Maximum. I.e. as in figure 2 it is shown, the Breadth Maximum A of second area 92 is the 1/2~2/3 of the Breadth Maximum B of first area 91.
Vibrating reed 8 is annular, 4~8 gap 9 being radially arranged along this annular, described 4~8 Gap 9 is uniformly distributed at the edge of vibrating reed 8, as shown in Figures 2 and 3.
Gap 9 is along the 2/3 of vibrating reed 8 a length of vibrating reed 8 internal-and external diameter difference radially.
Multiple vibrating reed 8, the gap of the plurality of vibrating reed 8 it is arranged with the most successively outside the lower end of oil pipe body 3 9 arrange in a spiral manner.The most as shown in Figures 2 and 3, the corresponding gap 9 of adjacent two vibrating reeds 8 staggers necessarily Angle, this angle is 30 °, the fluid in such oil pipe 3 pipe in move time be Flow Around, slow down flowing Resistance.
A kind of vibration wax-proof viscosity reducing oil pumping system, including above-mentioned vibration wax-proof viscosity reducing oil pipe, this vibration wax-proof viscosity reducing Oil pipe is contained within oil well pump 4, oil well pump 4 be arranged over sucker rod 5.Sucker rod 5 is outer to be arranged with the most successively Multiple vibrating reeds 8, the gap 9 of the plurality of vibrating reed 8 is arranged in a spiral manner.
During use, containing sleeve pipe 2 in oil well, having oil reservoir 1 outside sleeve pipe 2, this vibration wax-proof viscosity reducing oil pumping system is arranged In sleeve pipe 2, sucker rod 5 is outer and can be set with multiple vibrating reed according to actual needs on 3 outside the lower end of oil pipe body 8, as shown in Figure 1.
When upstroke, sucker rod 5 carrying, the fluid column weight in oil pipe body 3 is transferred to oil pumping by oil pipe body 3 On bar 5, when sucker rod 5 reaches upper dead center position, i.e. it is completely transferred to the moment of sucker rod 5 in fluid column weight, Fluid column weight on oil pipe body 3 discharges completely, and oil pipe body 3 produces and shrinks vibration, drives and oil pipe body 3 The vibrating reed 8 connected produces vibration, produces vibration wave and is delivered to oil reservoir 1, act on blocking after vibrating reed 8 vibration Grain, dredging duct, reach plugging removal effect.During down stroke, sucker rod 5 declines, in oil pipe body 3 fluid column weight by Sucker rod 5 is transferred on oil pipe body 3, when sucker rod 5 reaches lower dead point position, i.e. turns completely in fluid column weight Moving to the moment of oil pipe body 3, sucker rod 5 vibrates, and drives the vibrating reed 8 being connected with sucker rod 5 to produce and shakes Dynamic, it is brilliant that vibrating reed 8 produces wax in vibration wave acts on oil pipe body 3, plays destruction;Meanwhile, sucker rod 5 During up and down motion, liquid in oil pipe body 3 is played stirring action by vibrating reed 8, has certain viscosity reduction and prevents Wax effect;Additionally, there is gap 9 on sucker rod 5 vibrating reed, in oil pipe body 3, fluid produces one when gap 9 Fixed flow-disturbing effect, also functions to certain effect to viscosity reduction, wax control.
The advantage of this method, for vibration unplugging, wax control to be combined, serves dual function;Meanwhile, in oil well production During utilize the vibration of oil pipe, sucker rod self, do not increase extra work amount.
The above, the only specific embodiment of the present invention, it is impossible to limit the scope that invention is implemented with it, so its etc. With the displacement of assembly, or the equivalent variations made according to scope of patent protection of the present invention and modification, all should still fall within this patent The category contained.It addition, between technical characteristic and technical characteristic in the present invention, between technical characteristic and technical scheme, All can use with independent assortment between technical scheme and technical scheme.
