Detailed description of the invention
Understand for technical characterictic of the present utility model, object and effect being had more clearly, now contrast brief description of the drawings detailed description of the invention of the present utility model.
As shown in Figure 1, the compound wax-proofing apparatus of oil well of the present utility model, comprises body 1, spring leaf 2 and vibrating reed 4; Body 1 inwall has a necking part 3, and necking part 3 forms speed change passage; Multiple spring leafs 2 are arranged on the inwall of body 1, and are positioned at a side of necking part 3 fluids inflow ends; Vibrating reed 4 is positioned at a side of necking part 3 liquid outflow ends.
In a specific embodiment, on the inwall of body 1, be provided with multiple grooves 12, one end of spring leaf 2 can be set and is fixed in groove 12.
Be arranged on the stability on body 1 inwall in order to improve spring leaf 2, the projection that can match towards a side end setting and the groove 12 of groove at spring leaf 2, by this projection, spring leaf 2 can be stably embedded in groove 12, the other end of spring leaf 2 is to the center curvature of body 1.The elongated end of spring leaf 2 is no more than the center line of body 1,, the elongated end of spring leaf 2 equals the distance of described inboard wall of tube body to center line to the distance of body 1 inwall of fixing this spring leaf one side, to ensure that each spring leaf 2 can produce vibrations under the percussion of liquid stream, can not produce hooking each other.Otherwise, if the elongated end of spring leaf 2 is long, extend to body 1 center line opposite side,, in vibrations process, the elongated end of spring leaf 2 easily produces intersection hooking mutually, thereby will affect the vibrations paraffin removal effect of spring leaf 2.The fastness being connected with body in order to increase further spring leaf 2, also can be fixedly connected with spring leaf 2 at the side of groove 12 by fixed screw 21 with the inwall of body 1.In a described as shown in Figure 1, Figure 2 detailed description of the invention, spring leaf 2 be sheet, and wherein, spring leaf 2 sets that one end of being fixed in groove 12 is slightly wide and elongated end is tip.The spring leaf 2 of this device adopts groove 12 and the dual fixing mode of set bolt 21, has greatly extended the application life of this device.
A feasible scheme is, described groove 12 is arranged on the inwall of body 1 in the shape of a spiral, the multiple spring leafs 2 that are fixed in groove 12 are arranged in the shape of a spiral in body, have effectively extended and by spring leaf 2, liquid have been carried out the distance of mechanical paraffin removal, and be easy to install.
In addition, according to the diameter of body 1,8-12 flat spring sheet 2 can be set therein, cannot complete vibration back and forth when avoiding spring leaf 2 too intensive.In a preferred embodiment, spring leaf 2 is elected 8 as.
In the position that vibrating reed 4 is set, the inwall of the body 1 of the liquid outflow end of close necking part 3 is provided with the floor 5 radially connecting, and to fix vibrating reed 4, vibrating reed 4 is fixed on floor 5 and towards necking part 3.In a detailed description of the invention as shown in Figure 1-Figure 3, floor 5 is along the radially perforation setting of body 1 inwall, and what vibrating reed 4 adopted is wedge structure.Concrete, vibrating reed 4 is fixed on floor 5 by bolt 14.Because thereby vibrating reed 4 is produced sound wave by the high flow rate liquid flow impact vibration after necking part 3 accelerates, in order to ensure that vibrating reed 4 further destroys the effect of thin reduced wax crystal, is fixed on vibrating reed 4 on the axle center of necking part 3.
In the time using this device, use for the ease of connecting, the end that flows into one end at this device fluid is provided with connecting thread 6, and the termination of flowing out one end at this device liquid is provided with box cupling 7.
Use the compound wax-proofing apparatus of oil well of the present utility model in oil well production process time, be that this device is arranged under oil well pump, wax-proofing apparatus of the present utility model two ends are connected with sucker rod.In this device busy process, liquid stream first passes through the spring leaf 2 in body 1, and spring leaf 2 can produce vibration back and forth with throw of pump and under the effect of liquid stream, and wax crystalline substance is destroyed under the effect of vibration of spring leaf 2, can not condense, and reaches the first heavy wax control object.While flowing through the liquid of spring leaf 2 wax controls the speed change passage forming through necking part 3, accelerate to form high flow rate liquid stream, high flow rate liquid flow impact vibrating reed 4, vibrating reed 4 is subject to generation of vibration sound wave, further destroys thin reduced wax crystal, reaches the second wax control object weighing.
The compound wax-proofing apparatus of oil well of the present utility model has improved wax control result effectively by the double action of mechanical oscillation wax control and sound wave wax control, also has the effect of viscosity reduction simultaneously.Use this device can effectively reduce wax removal number of times, save production cost.
The foregoing is only the schematic detailed description of the invention of the utility model, not in order to limit scope of the present utility model.Any those skilled in the art, is not departing from equivalent variations and the amendment under the prerequisite of design of the present utility model and principle, done, all should belong to the scope of the utility model protection.And it should be noted that, each ingredient of the present utility model is not limited in above-mentioned overall applicability, each technical characterictic of describing in manual of the present utility model can select one to adopt separately or select the multinomial use that combines according to actual needs, therefore, the utility model has naturally been contained other combinations relevant with this case innovative point and specifically application.
