Description
Technical field:
The utility model relates to the used chemicals dosing plant of oil field petroleum production engineering well head, especially screw-pushing type solid chemicals well head chemicals dosing plant.
Background technology:
In oil recovery field, oil field, in order to prevent underground equipment wax deposition and fouling, need add the medicament of anti-wax deposition and fouling to down-hole well liquid, guarantee that underground equipment normally moves.And the oil well chemicals dosing plant mainly is the liquid dosing at present, mostly is the drip dosing, well head drop dosing major defect, and the one, medicament hangs on the casing wall easily, is stuck in sometimes on the wax deposition of liquid level, makes medicament can not bring into play effect; The 2nd, lose motor component easily; The 3rd, medicament viscosity increases in the winter time, can't operate as normal, accelerated the speed of underground equipment wax deposition and fouling, and influence is normally recovered the oil.
The utility model content:
In order to solve the problem in the background technology, the utility model provides a kind of screw-pushing type solid chemicals well head chemicals dosing plant, and this screw-pushing type solid chemicals well head chemicals dosing plant has the advantages that to delay underground equipment wax deposition and scale velocity.
The technical solution of the utility model is: this screw-pushing type solid chemicals well head chemicals dosing plant comprises that front end has the seating nipple of clip head, the seating nipple upper end is connected with the grug feeding jar that communicates with it, the water filling joint that the band valve is arranged on the grug feeding jar, the pressure relief opening that the band valve is arranged below the seating nipple, be connected with positioning sleeve in the seating nipple right-hand member, positioning sleeve is built-in with supporting positive cover, supporting positive cover is built-in with the dosing axle, be equipped with mechanical seal on the dosing axle in the supporting positive cover, the positioning sleeve right-hand member is externally connected with lock sleeve, and dosing axle left part external fixation has spiral hinge sheet in the seating nipple.
The stage through hole of lock sleeve right-hand member is built-in with bearing on the dosing axle in the such scheme; The pressure tappings that the band valve is arranged on the seating nipple; Be filled with the sealing ring that touches mutually with the dosing axle in the inner groovy of lock sleeve right-hand member hole; Between positioning sleeve and dosing axle and positioning sleeve and seating nipple sealing ring is arranged respectively.
The utlity model has following beneficial effect: this screw-pushing type solid chemicals well head chemicals dosing plant is owing to take such scheme, medicament enters in the seating nipple under the impact of water, again by rotation dosing axle, by cutting with scissors sheet medicament is cut with scissors in the oil pipe and sleeve pipe annular space of down-hole, and be dissolved in rapidly in the well liquid by spiral on the dosing axle.Thereby effectively delay the speed of underground equipment wax deposition and fouling, prolonged the underground equipment life cycle, reduced cost for oil production, and simple in structure, guaranteed the normal operation of oil.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-seating nipple among the figure, 2-grug feeding jar, 3-water filling joint, 4-positioning sleeve, 5-supporting positive cover, 6-dosing axle, 7-lock sleeve, 8-bearing, 9-spiral hinge sheet, 10-pressure relief opening, 11-pressure tappings, 12-sealing ring.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this screw-pushing type solid chemicals well head chemicals dosing plant comprises that front end has the seating nipple 1 of clip head, seating nipple 1 upper end is welded with grug feeding jar 2, be welded with the water filling joint 3 of band valve on the grug feeding jar 2, open inwardly adding medicine of grug feeding jar 2 loam cakes, and can the pharmacists be sent in the seating nipple 1 by the water of water filling joint 3, water filling joint 3 is connected with the water source, and by the valve control water yield and switch; Seating nipple 1 upper end is welded with the pressure tappings 11 of band valve, is welded with the pressure relief opening 10 of band valve below the seating nipple 1, can record oil jacket pressure by pressure tappings 11, can let out except that pressure and raffinate in the grug feeding jar 2 by pressure relief opening 10; Seating nipple 1 right-hand member is interior by the positioning sleeve 4 that has been threaded, positioning sleeve 4 is built-in with supporting positive cover 5, supporting positive cover 5 is built-in with dosing axle 6, be equipped with mechanical seal on the dosing axle 6 in the supporting positive cover 5, positioning sleeve 4 right-hand members are outer by the lock sleeve 7 that has been threaded, the 6 left part outside welds of dosing axle are connected to spiral hinge sheet 9 in the seating nipple 1, the stage through hole of lock sleeve 7 right-hand members is built-in with bearing 8 on the dosing axle 6, be filled with the sealing ring 12 that touches mutually with dosing axle 6 in the lock sleeve 7 right-hand member hole inner groovies, 6 on positioning sleeve 4 and dosing axle have sealing ring, 1 of positioning sleeve 4 and seating nipple have sealing ring, and sealing ring 12 is to prevent medicament and pressure leakage.By supporting positive cover 5 and bearing 8 in the positioning sleeve 4 dosing axle 6 is supported on seating nipple 1, be fixed by lock sleeve 7 and mechanical seal again, again by mechanical seal and sealing ring 12 to its sealing, at last with spanner rotation dosing axle 6, by the hinge of the spiral on the dosing axle 6 sheet 9 medicament is cut with scissors the annular space that oil-feed is overlapped, reach the destination of dosing in oil well.
During actual the use, at first the clip head on the seating nipple 1 is connected on the big four and is connected with oil well casing by clip, close sleeve valve then earlier, the cut-out pressure source, close oil well again and come penstock, cut off water pressure, open the valve on the pressure relief opening 10, bleed off pressure and raffinate in the grug feeding jar 2, open the loam cake dosing of grug feeding jar 2 again, close the loam cake of grug feeding jar 2 after the dosing again, close the loam cake of grug feeding jar 2 after, open valve and sleeve valve on the water filling joint 3 again, at this moment with spanner rotation dosing axle 6, dosing axle 6 rotation was closed valve and sleeve valve on the water filling joint 3 after 3-5 minute, opened the valve on the pressure relief opening 10 and the loam cake of grug feeding jar 2 again, observation adds dose, after confirming that dosing is finished, close the valve on the water filling joint 3, valve on the water filling joint 3 and sleeve valve and sleeve valve are finished the dosing process one time.Because of medicament enters under the impact of water in the seating nipple 1,, by cutting with scissors sheet 9 medicament is cut with scissors in the oil pipe and sleeve pipe annular space of down-hole, and be dissolved in rapidly in the well liquid by spiral on the dosing axle 6 again by rotation dosing axle 6.Thereby effectively delay the speed of underground equipment wax deposition and fouling, prolonged the underground equipment life cycle, reduced cost for oil production, and simple in structure, guaranteed the normal operation of oil.This screw-pushing type solid chemicals well head chemicals dosing plant has the advantages that to delay underground equipment wax deposition and scale velocity thus.
