Abstract
The utility model relates to a magnetic single flow valve, which is designed for washing pipe columns for low pressure oil well by heating washing. The magnetic single flow valve can improve the method of heating washing for traditional pipe columns. The heating washing of paraffin removal has good effect, and fluid for washing a wall can stop back flow; the oil layer can not be contaminated. The resistance force of a check valve for entering pump is reduced. Energy is saved, and the oil effect of oil pumping is improved. The magnetic single flow valve is composed of a valve body, a ball cover, a sucking block, a valve ball, a ball bse, a lower connecter, etc., wherein, the sucking block is composed of a magnetic block, a magnetism separating block, and a magnetism separating pad. The magnetic single flow valve has the advantages of simple structure, convenient pressure test, material saving, easy fabrication, and good effect on heating washing.
Description
The utility model relates to a kind of magnetic one-way valve that low pressure oil well heat is washed that is used for, and belongs to oil well downhole tool class.
Oil well is in order to obtain high yield, often to clean oil well, traditional cleaning oil well method is to wash tubing string with heat to wash one-way valve by heat, when the clear cured heat of oil well is washed, cause flushing fluid to pour in down a chimney easily to oil reservoir, and the severe contamination oil reservoir wastes energy, has reduced the oil pumping timeliness, simultaneously owing to overcome heat and wash the unlatching of one-way valve valve ball and cause that into the pump resistance is big.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and provides the low pressure oil well heat after a kind of the improvement to wash the magnetic one-way valve.
The utility model is achieved in that
When the utility model uses, be bound up on by the screw thread box cupling inside the oil pipe of packet bottom and oil well pump upper position, it comprises by valve body (1), ball cover (2), suction piece (3), valve ball (4), block (5), ball seat (6), O circle (7), lower contact parts such as (8) and forming.Wherein inhale piece by magnetic block, form every magnetic patch, magnetic isolating pad.Valve body (1) links to each other with screw thread with ball cover (2), lower contact (8); The ball cover side direction has four pressure guide holes.(among the figure draw) valve body has a step above (1), suction piece (3), block (4), valve seat (5) is arranged below the step, and valve body links to each other with the lower contact screw thread, and there are two O ring recess in lower contact (8) outside, encloses by O to reach sealing effect.Wherein the material every magnetic patch is a red copper, and magnetic isolating pad is H
68Red copper material, magnetic block are that permanent-magnet material is manufactured.
Tubing string is when ordinary production, and magnetic single current valve ball is in opening state, has reduced crude oil and has advanced the pump resistance, crude oil is from valve, and the inner chamber of cup packer enters pump barrel, is pumped into ground then, because packet has and bears unidirectional pressure reduction function, pressure reduction is zero instantly, and oil well still keeps producing fluid level.Draining when playing lift pipe string, the pressure release effect, and minimizing oil flows to pump resistance purpose.
During well-flushing, the flushing fluid of enough discharge capacities impacts ball valve (4), overcomes the magnetic attraction of inhaling piece, makes ball valve fall the ball seat below and closes the flushing valve attempt and enter formation channels, makes flushing fluid through pump, returns in oil pipe, reaches and does not pour in down a chimney the stratum purpose.
The utility model advantage is:
Owing to adopted magnetic one-way valve well-flushing to stop flushing fluid not pour in down a chimney to oil reservoir, play not polluted reservoir effect, in addition because the magnetic one-way valve is in opening state has reduced oil and flow to the pump resistance, the effect that is used in particular in the thick oil well is bigger.
The utility model is provided by following examples:
Illustrated below in conjunction with accompanying drawing
Accompanying drawing: the utility model structural representation
During assembling, at first will be with magnetic block, be embedded in the suction piece (3) that magnetic isolating pad is combined in simultaneously every magnetic patch, be placed in the valve body (1), then, put into a link stopper (5) again, put into a ball seat (6) again in the lower end in suction piece lower end, and valve ball 4 put into seat, subsequently " O " RunddichtringO groove is inserted in above the last screw thread groove of lower contact 8, be screwed in valve body 1 above, get final product.
Magnetic one-way valve among the embodiment is made up of valve body (1), ball cover (2), suction piece (3), valve ball (4), block (5), valve seat (6), O circle (7), lower contact (8).During work and tension force lock, anchor, rod pump, packet be used.(not drawing among the figure)
Claims (2)
1. one kind is used for the magnetic one-way valve that oil field heat is washed, and is made up of valve body (1) and the lower contact (8) that is bound up on valve body lower end; It is characterized in that being equipped with in the valve body magnetic block, be combined in magnetic isolating pad after simultaneously suction piece (3) is embedded in every magnetic patch; Put in the valve body (1), inhaling the piece lower end has a link stopper (5), and there is a ball seat (6) the link stopper lower end, puts into a ball valve (4) in the seat, and the lower contact 8 that has " O " RunddichtringO to be inserted in, and is screwed in valve body (1) lower end by screw thread.
2. magnetic one-way valve according to claim 1; The magnetic block that it is characterized in that inhaling in the piece (3) is a permanent-magnet material, magnetic isolating pad, is H every magnetic patch
68The red copper material.
