Abstract
The utility model discloses a demulsification and paraffin removal device for an oil well. The demulsification paraffin removal device comprises an upper joint, wherein the upper joint is connected with a joint that is connected with a central pipe; and the central pipe is connected with a lower joint; and a solid paraffin removal and inhibition agent is arranged in the central pipe. A spring piece bearing is arranged below the lower joint, and connected with a first spring piece and a second spring piece, wherein the first spring piece and the second spring piece are mutually overlapped. With the adoption of the demulsification paraffin removal device, the output liquid of the oil well is subject to the demulsification and paraffin removal, therefore, the viscosity of the output liquid of the oil well can be reduced, the flowing capacity can be improved, the demulsification and the paraffin removal can be achieved, the well-flushing period can be prolonged, and thus the output of the crude oil is increased.
Description
Technical field
The utility model belongs to the broken wax apparatus technical field of oil well, relates to a kind of oil well breakdown of emulsion paraffin removal unit.
Background technology
Gather in the oil process at oil pumping machine oil pumping, because oil well paraffinication, oil pipe endoporus area reduces gradually, and the sucker rod frictional resistance constantly increases, and causes the oil pumper load constantly to increase, and causes oil pipe to stop up oil well output and reduces, and the rod parting accident constantly increases.Solve at present both at home and abroad this type of problem and mainly be divided into machinery, chemistry, electric heating, heat and the broken wax of multiple mode such as wash, its effect has nothing in common with each other to different oil wells.
Heating is promptly regularly dissolved the paraffin in the oil well with deep fat or hot water circuit well-flushing, the dredging pipe circulation road, and this method weak point is to increase operation to account for the well time and influence output, causes oil layer pollution easily.The clear wax control method of chemistry through the continuous or periodic chemical agent that in oil well, adds, 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.The mechanical type paraffin scraper utilizes mechanism to wear and tear to remove institute's wax deposition piece to let oil stream that it is carried out well head; But its problem is to be prone to cause card stifled, is difficult for being lowered to the serious position of wax deposition, does not possess effectively anti-wax deposition effect.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.
The utility model content
The technical problem that the utility model solves is to provide a kind of oil well breakdown of emulsion paraffin removal unit, can carry out the breakdown of emulsion wax removal to produced liquid in oil well, reaches the reduction viscosity of produced liquid in oil well; Increase fluid ability; Breakdown of emulsion, wax control prolong time between well-flushings, thereby increase crude output.
The utility model is to realize through following technical scheme:
A kind of oil well breakdown of emulsion paraffin removal unit comprises top connection, and top connection links to each other with joint, and joint links to each other with central tube, and central tube connects lower contact, is provided with the solid Wax removing agent in the central tube.
The below of described lower contact is provided with the spring leaf bearing, and the spring leaf bearing is connected with second spring leaf with first spring leaf that is superimposed with each other.
Be provided with valve ball and valve seat in the described top connection, valve seat is positioned at the junction of joint and top connection.
Compared with prior art, the utlity model has following beneficial technical effects:
The oil well breakdown of emulsion paraffin removal unit that the utility model provides, when sucker rod up drew, oil well crude oil got into through lower contact; Successively through central tube, joint and top connection; When crude oil process central tube,, can reduce viscosity of produced liquid in oil well owing to be provided with the solid Wax removing agent in the central tube.
Further; First spring leaf and second spring leaf are set below lower contact, and crude stream is out-of-date, and spring leaf eddy oscillating effect changes the flow behavior of crude oil; Effectively brilliant the separating out of the gathering of paraffin molecule and wax in the crude oil for inhibiting; Effectively stop the brilliant formation of wax, the big acale wax that disperse, fragmentation has formed is brilliant, thereby reaches the effect of wax removal.
Further, in top connection valve ball and valve seat are set, under the oil well pump suction function, valve ball is just down blocked valve seat, and to reduce the leakage of the above crude oil of valve seat, crude oil is through being promoted to the joint simultaneously; When sucker rod walked downward, valve ball was pushed up from valve seat, and crude oil gets into top connection through valve seat, thereby enters into oil pipe.Thereby increase the suction of oil pumping, reduce the leakage of crude oil, improve oil well pump and render a service, particularly in deep-well, use, effect is more obvious, thereby increases crude output.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein: 1 is top connection; 2 is valve ball; 3 is valve seat; 4 is joint; 5 is central tube; 6 are lower contact; 7 is first spring leaf; 8 is second spring leaf; 9 is the spring leaf bearing; 10 is the solid Wax removing agent.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done to describe in further detail, said is explanation rather than qualification to the utility model.
Referring to Fig. 1, a kind of oil well breakdown of emulsion paraffin removal unit comprises connecing 1 that top connection 1 links to each other with joint 4, and joint 4 links to each other with central tube 5, and central tube 5 connects lower contact 6, is provided with solid Wax removing agent 10 in the central tube 5.
Further, below lower contact 6, be provided with spring leaf bearing 9, spring leaf bearing 9 is connected with second spring leaf 8 with first spring leaf 7 that is superimposed with each other.First spring leaf and second spring leaf are set below lower contact; When crude stream is crossed the spring leaf bearing; Spring leaf eddy oscillating effect can change the flow behavior of crude oil, and then the gathering of paraffin molecule and separating out of wax crystalline substance in effective crude oil for inhibiting, effectively stops the brilliant formation of wax; The big acale wax that disperse, fragmentation has formed is brilliant, thereby reaches the effect of wax removal.
Further, 1 is provided with valve ball 2 and valve seat 3 in top connection, and valve seat 3 is positioned at joint 4 and top connection 1 junction.Under the oil well pump suction function, valve ball is just down blocked valve seat, and to reduce the leakage of the above crude oil of valve seat, crude oil is through being promoted to the joint simultaneously; When sucker rod walked downward, valve ball was pushed up from valve seat, and crude oil gets into top connection through valve seat, thereby enters into oil pipe.Thereby increase the suction of oil pumping, reduce the leakage of crude oil, improve oil well pump and render a service, particularly in deep-well, use, effect is more obvious.
The oil well breakdown of emulsion paraffin removal unit that the utility model provides can carry out the breakdown of emulsion wax removal to produced liquid in oil well, reaches the reduction viscosity of produced liquid in oil well, increases fluid ability, and breakdown of emulsion, wax control prolong time between well-flushings, and improves pump efficiency, thereby increases crude output.
