Description
Technical field:
The utility model relates to a kind of oil well casing wax scavenge unit, particularly a kind of sleeve pipe paraffin cleaner that is used for the high-solidifiability oil well operation process.
Background technology:
In the oilfield process, in oil well casing, when the crude oil temperature in the pit shaft was lower than the crude oil freezing point temperature, the crude oil that adheres on the pit shaft inner surface will solidify.The crude oil that solidifies diminishes casing inner diameter, in the production operation work progress, easily cause under the flow string and do not go promptly to be hampered, at present, the method that adopts after being hampered is that drift size gauge tool heat is washed drifting down, there are deficiencies such as difficulty of construction is big, the cycle is long, cost is high, weak effect in this method, have a strong impact on oil well and normally reproduce, adopt a large amount of hot water well-flushings simultaneously, cause oil layer pollution easily.
The utility model content:
The technical problems to be solved in the utility model provides a kind of sleeve pipe paraffin cleaner, and this sleeve pipe paraffin cleaner has been realized can cold water removing casing wall and adhered to wax, and developing result is good, and cost is low, shortens the individual well construction period.Overcome prior art and can only use hot water injection's casing wax, developing result is poor, the high and big deficiency of difficulty of construction of cost.
Technical solution adopted in the utility model is: a kind of sleeve pipe paraffin cleaner, form by pipe, urceolus, upper bearing (metal) gland, sealing ring, OE rotating seal ring, deep groove ball bearing, transition joint, rotating shaft, y-type seal ring, lower bearing gland, back of the body cap, sealing ring, following valve body and ejectisome in top connection, valve ball cover, valve ball, valve seat, upper valve body, filtration body, the filtration; Be between top connection and upper valve body, upper valve body and urceolus, urceolus and the upper bearing (metal) gland and be threaded, be linked in sequence between upper bearing (metal) gland, transition joint, the lower bearing gland, the valve ball cover links to each other with upper valve body, valve ball places in the valve seat, pipe welding in filtering body and filtering, the lower end of filtering body is connected with the upper bearing (metal) gland, is deep groove ball bearing between transition joint and the rotating shaft, rotating shaft is connected with following valve body, and following valve body is threaded with ejectisome.
All adopt the sealing of sealing ring and OE rotating seal ring between upper bearing (metal) gland and transition joint, transition joint and the lower bearing gland.
Adopt the y-type seal ring sealing between rotating shaft and the lower bearing gland, adopt the sealing ring sealing between rotating shaft and the following valve body.
The beneficial effects of the utility model are: the utility model is because pipe welding in having adopted the filtration body and having filtered, the lower end of filtering body is connected with the upper bearing (metal) gland, it between transition joint and the rotating shaft deep groove ball bearing, rotating shaft is connected with following valve body, the structure that following valve body is threaded with ejectisome, thereby have and to remove casing wall adhesion wax, the advantage that developing result is good by cold water.The utility model has reduced the individual well operating cost, shortens the individual well construction period, improves the operation timeliness, and simple, the convenient and the utility model of site operation can be used repeatedly.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
As shown in drawings, a kind of sleeve pipe paraffin cleaner is made up of pipe 7, urceolus 8, upper bearing (metal) gland 9, sealing ring 10, OE rotating seal ring 11, deep groove ball bearing 12, transition joint 13, rotating shaft 14, y-type seal ring 15, lower bearing gland 16, back of the body cap 17, sealing ring 18, following valve body 19 and ejectisome 20 in top connection 1, valve ball cover 2, valve ball 3, valve seat 4, upper valve body 5, filtration body 6, the filtration; Be between top connection 1 and upper valve body 5, upper valve body 5 and urceolus 8, urceolus 8 and the upper bearing (metal) gland 9 and be threaded, be linked in sequence between upper bearing (metal) gland 9, transition joint 13, the lower bearing gland 16, valve ball cover 2 links to each other with upper valve body 5, valve ball 3 places in the valve seat 4, pipe 7 welding in filtering body 6 and filtering, the lower end of filtering body 6 is connected with upper bearing (metal) gland 9, be deep groove ball bearing 12 between transition joint 13 and the rotating shaft 14, rotating shaft 14 is connected with following valve body 19, and following valve body 19 is threaded with ejectisome 20.
All adopt sealing ring 10 and 11 sealings of OE rotating seal ring between upper bearing (metal) gland 9 and transition joint 13, transition joint 13 and the lower bearing gland 16.
Adopt y-type seal ring 15 sealings between rotating shaft 14 and the lower bearing gland 16, adopt sealing ring 18 sealings between rotating shaft 14 and the following valve body 19.
During the utility model site operation, top connection 1 is connected on the oil pipe below pin thread of oil well pipe, G.I.H.Arrive oil well casing paraffin-troubled well section, utilize cementing truck that High-Pressure Water is entered the utility model by oil pipe.Because 3 of valve balls are in valve ball base 4, High-Pressure Water enters urceolus 8 by the runner in the upper valve body 5, after filtering with the interior pipe 7 of filtration, body 6 enters upper bearing (metal) gland 9 by filtering, enter rotating shaft 14, following valve body 19 arrival ejectisomes 20 successively, become high-pressure spray through the injection runner that is provided with in the ejectisome 20, high-pressure spray is realized the cutting of casing wax.Wherein the high-pressure spray that ejects of ejectisome 20 drives rotating shaft 14 and ejectisome 20 etc. and is rotated, thereby realizes that casing wall 360 degree adhere to waxes and remove.Progressively transfer the sleeve pipe paraffin cleaner during construction, can realize that whole internal surface of sleeve pipe adheres to the removing of wax.Pipe 7 in the utility model adopts and filters has been realized High-Pressure Water is filtered, and prevents the purpose of plug nozzle; Adopt valve ball 3, valve ball cover 2, valve seat 4 and upper valve body 5, can realize the oil well anti-flushing well.
