Abstract
The utility model relates to a disc-type churning-oscillation and viscosity-reducing antiwax apparatus for a pumping rod and belongs to the technical sphere of sucker-rod pumping equipment, which comprises an upper connector, a body of a center pole and a lower connector consecutively and is arranged on the pumping rod at any well depth, wherein 10-18 disc vibrating reeds are arranged side by side on the body of the center pole, 4-8 slotted holes are arranged on each disc vibrating reed, the width of each slotted hole is 3-5 millimeters, the width between every two disc vibrating reeds is 30-50 millimeters, and the adjacent slotted holes between every two disc vibrating reeds are not coplanar. In the process of the up-and-down movement of the pumping rod, the mechanical shearing and stirring action is taken between the disc vibrating reeds and fluid, reducing the viscosity of the fluid. When the fluid flows through the slotted holes on the disc vibrating reeds, the violent churning oscillation is generated because of the certain angles staggered by slotted holes between adjacent vibrating reeds and damages the wax-crystal structure, realizing the aims of the viscosity reduction and the antiwax.
Description
Technical field:
The utility model belongs to the adhesion reducing and wax preventing device that has in bar the oil production equipment technical field, particularly oil well.
Background technology:
High content of wax high freezing point oil Yin Wendu in process of production reduces and to cause the wax deposition phenomenon, and tube fluid viscosity increased, flow resistance are increased, when serious even cause oil well to stop production.Solve at present both at home and abroad this type of problem and mainly contain following several method: 1. heating, promptly regularly dissolve paraffin in the oil well, dredging pipe circulation road with deep fat or hot water circuit well-flushing.The weak point of this method is to increase operation to account for the well time and influence output, in addition, causes oil layer pollution easily and influences the oil well ordinary production with the hot water well-flushing.2. the clear wax control method of chemistry by the continuous or periodic chemical agent that adds in oil well, suppresses the brilliant growth of wax or removes the paraffin blockage phenomenon that pipeline section is stopped up in wax deposition formation.But this method will be selected suitable chemical agent according to different wax components, and the production scene is difficult to realize the high-efficiency and continuous dosing, and the price of chemical agent is higher.3. mechanical type paraffin scraper, utilize mechanism to wear and tear to remove institute's wax deposition piece to allow oil stream that it is carried out well head, but its problem is easily to cause card to block up, and also is difficult for being lowered to the serious position of wax deposition sometimes, and operation accounts for the long influence of well time and produces, and does not possess effectively anti-wax deposition effect.4. strong magnetic preventing wax device is a kind of wax-preventing method that utilizes magnetic field to be used for reaching to prevent wax deposition, but parameter such as magnetic field intensity and magnetic flux and fluid-mixing component content factors can influence wax control result, can reduce wax control result along with wax control device is aging.5. acoustic vibration adhesion reducing and wax preventing device, this technology are to utilize fluid dynamic energy excite sound waves generator and produce acoustic vibration, stop the brilliant crystalline growth of wax to reach a kind of anti-wax technique that delays wax deposition.But the structure of this kind wax control device has limitation, and it can only be connected under the oil well pump, is difficult to use in the tubing string on the pump, so cause the darker oil well paraffin prevention effect of wax deposition point undesirable.
Summary of the invention:
The purpose of this utility model is that a kind of disk type eddy oscillating viscosity-reduction paraffin control device for use in sucker rod will be provided, to solve the oil well paraffinication problem.
The purpose of this utility model is to realize like this, the eddy oscillating wax control device is installed side by side on the body of rod of center by 10～18 disk type vibrating reeds and is formed, be connected any well depth position on the sucker rod by upper and lower joint, have 4～8 slots on the every disk type vibrating reed, the width of every slot is 3～5 millimeters, distance between the two adjacent disk type vibrating reeds is 30～50 millimeters, and the slot of adjacent disc chip vibrating sheet is not at grade.
The utility model is owing to installed 10～18 disk type vibrating reeds side by side on same center-pole, at sucker rod up and down in the running, produce the mechanical shearing stirring action between disk type vibrating reed and the liquid, cause liquid viscosity to reduce, produced simultaneously multifrequency vibration ripple is propagated in liquid also to liquid generation effect.Owing to all have slot on slot and the adjacent vibrating reed certain angle that all staggers on the vibrating reed, so on the slot of liquid on vibrating reed during current downflow, can produce violent eddy oscillating, under the adjection of eddy oscillating field, liquid is further handled, destroy wax-crystal structure thus, reduce the purpose that viscosity of crude reaches wax-proof viscosity reducing.
Description of drawings:
Fig. 1 is the structural representation of the disk type eddy oscillating viscosity-reduction paraffin control device for use in sucker rod that proposes according to the utility model.
Fig. 2 is the sectional view of disk type vibrating reed shown in Figure 1 along the A-A line.
The specific embodiment:
Describe concrete structure of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1; this wax control device is linked in sequence and is constituted by top connection 1, the center body of rod 2, lower contact 5; 10～18 disk type vibrating reeds 3 are installed on the center body of rod 2 side by side; have 4～8 slots on the every vibrating reed 3; the width of every slot is 3～5 millimeters; distance between the two adjacent disk type vibrating reeds is 30～50 millimeters; the slot of adjacent disc chip vibrating sheet certain angle that staggers; the below of vibrating reed is installed near lower contact 5 places and is set upright protector 4, is used for protecting vibrating reed not broken when transferring.The two ends of the center body of rod are upper and lower joints, connect sucker rod respectively, can be installed in any well depth position.In the running, produce the mechanical shearing stirring action between disk type vibrating reed 3 and the liquid about sucker rod, cause liquid viscosity to reduce, produced simultaneously multifrequency vibration ripple is propagated in liquid also to liquid generation effect.On the slot of liquid on vibrating reed during current downflow, owing to the certain angle that all staggers of the slot on the adjacent vibrating reed produces violent eddy oscillating, under the adjection of eddy oscillating field, liquid is further handled, destroy wax-crystal structure thus, reduce the purpose that viscosity of crude reaches wax-proof viscosity reducing.This device is used for high content of wax high freezing point oil and adopts the oil well production of sucker rod pumping artificial lifting way.
