The efficient emulsification one-way watering valve of the heavy oil well pump is of a cylindrical tube structure, internal threads are arranged on the upper portion of a central hole of the upper connector, the longitudinal section of the upper connector is Y-shaped, two stages of internal threads are arranged on the lower portion of the central hole, the internal threads and the two stages of internal threads are respectively connected with the outer working cylinder and the inner working cylinder, an upper-ring cavity is arranged between the outer working cylinder and the inner working cylinder, and cutting-line kerfs are evenly arranged inside the inner working cylinder. The lower end of the outer working cylinder is in threaded connection with the lower connector, the lower end of the inner working cylinder is in threaded connection with the inner connector, the spring and the seal ring are arranged between the inner connector and the lower connector, a lower-ring cavity is formed between the inner connector of the lower portion of the seal ring and the lower connector, a changeable nozzle is arranged on the lower connector faced with the lower-ring cavity, and external threads are arranged on the lower portion of the lower connector. The efficient emulsification one-way watering valve of the heavy oil well pump is reasonable in design and novel in structure, good in watering and oil flow emulsification mixing, improves the effect of a watering process on a pump, and increases the crude output of the heavy oil well.
Description
Technical field
The utility model relates to water mixing control device on the oil-field thick-oil well production pump, specifically efficient emulsification one-way watering valve on a kind of viscous crude well pump.
Background technology
Viscous crude has that viscosity is large, the characteristics of poor fluidity, and the exploitation difficulty is larger.Mainly adopt at present water mixing technique on the thickened-oil pump.Adopt screen casing as circulation water mixing connectivity points on the pump in the water mixing process pipe string structure always, therefore in the oil well daily management, often occur owing to cut off the water, have a power failure former thereby cause that viscous crude assembles at the oil jacket annular space, cause the water mixing pressure rise, stop up the problem of cased borehole.Simultaneously, in the water mixing process, because day watering quantity is at 20-40m
3, mix water and formation oil undercompounding, affect water mixing lifting effect.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and efficient emulsification one-way watering valve on a kind of viscous crude well pump is provided.
The technical scheme that its technical problem that solves the utility model adopts comprises: top connection, outer working tube, interior seating nipple, spigot, spring, joint ring, lower contact.Efficient emulsification one-way watering valve is the cylindrical tube body structure on its viscous crude well pump, the top connection centre bore top that the vertical section is " protruding " font is provided with internal thread, the bottom is provided with the two-stage internal thread, connecting respectively outer working tube, interior seating nipple, be upper annular space between outer working tube and the interior seating nipple, interior seating nipple is provided with the tangent line slot of equal section; The outer working tube lower end is threaded with lower contact, interior seating nipple lower end is threaded with spigot, be provided with spring, joint ring between spigot and the lower contact, form lower annular space between the bottom spigot of joint ring and the lower contact, be provided with nozzle in lower contact facing to lower annular space place, nozzle diameter can be matched as required, and the lower contact bottom is provided with external screw thread.
Operating principle:
Sewage through heating mixes from the tubing and casing annular space, because after downhole packer sets, pit shaft is divided into up and down two parts, mixes water and more than packer, build the pressure, when pressure surpasses spring pressure, back down joint ring, mix water through nozzle, lower annular space, upper annular space, and pass through the slot on interior seating nipple surface, be jet-like and fully mix with formation oil, return ground flow along oil pipe, realize the reducing viscosity by emulsifying of water mixing fluid and stratum viscous crude.When stopping well, joint ring can be closed rapidly the water mixing passage under the level pressure spring action simultaneously, avoids the interior viscous crude of oil pipe to enter the oil jacket annular space.
The beneficial effects of the utility model are: reasonable in design, and novel structure, the eddy flow design of slot can better mix water mixing with the emulsification of oil stream.Thereby water mixing technological effect on the raising pump reduces heavy oil wells production management difficulty, improves the heavy oil wells crude output, reduces cost of crude oil production.
