Abstract
The utility model relates to a device for washing a well, and discloses a fluid amount increasing device for washing the well. The fluid amount increasing device for washing the well comprises a body. The fluid amount increasing device for washing the well is characterized in that an upper fluid feeding hole is formed in the upper portion of the body, a fluid discharging hole is formed under the upper fluid feeding hole, the upper fluid feeding hole is communicated with the fluid discharging hole, a fluid feeding ball valve is movably arranged at the position of the upper fluid feeding hole, a ball valve chamber is formed at the position of the fluid discharging hole, and a moving ball valve is arranged inside the ball valve chamber. The fluid increasing device for washing the well can avoid the situations that when a traditional hot washing method is used, well washing fluid has a well killing function on an oil layer, and the oil layer is contaminated after the well washing fluid enters the oil layer, suction force of an oil sucking pump is enhanced, the loss of the pump is reduced, the amount of the discharged fluid is increased, and the efficiency of the pump is improved.
Description
Technical field
The utility model relates to a kind of well-flushing device.
Background technology
The old filed that more present development times are long, liquid level is dark, and is moisture low, content of wax height, freezing point height.Traditional sleeve pipe hot-washing wax remover is the main wax removal mode of this block Oilfield using, but there is following shortcoming in this wax removal mode: it is long that (1) heat is washed the time, and the oil well evenly heat that general well depth is 2000M is washed for up to 5h; (2) well-flushing efficient is low, and heat utilization ratio is low.Overwhelming majority heat was dissipated in casing wall and nearly borehole wall area thereof when sleeve pipe heat was washed, and also had the heat of part to be lost in the stratum with the flushing fluid of missing, and really was used for the shortage of heat 30% of hot-washing wax remover; (3) lost circulation is serious, and about 10 cubic metres of average individual well lost circulation has caused serious pollution to oil reservoir; (4) to the well of glass fiber reinforced plastic oil pumping rod is arranged down, the high flushing fluid of preventing is bigger to its infringement when heat is washed.At the problems referred to above, we once taked following measure: (1) cooperates heat to wash the clear wax control of enforcement chemistry, since this method is used, though prolonged hot washing period to a certain extent, but still have the problem of flushing fluid polluted reservoir.(2) the anti-pollution packer of supporting application, though it is this instrument can prevent that to a certain extent flushing fluid from entering the people stratum, because the packing element of packer is subjected to the influence of high temperature flushing fluid, easily aging cracked, use at the scene and caused many down-hole accidents, now potassium hydroxide.(3) supporting being applied in placed the switch of giving up under the pump, and this instrument can prevent effectively that flushing fluid from entering the stratum.But owing to reasons such as formation sand productions, often cause the overhaul accident, now need not.(4) to the well of glass fiber reinforced plastic oil pumping rod is arranged down, requirement flushing fluid temperature should not be too high when heat was washed, and washes not thorough but cause again like this to the wax deposition heat of oil well.Reached and increased the purpose that liquid is put forward effect.
Summary of the invention
At the problem that exists in producing, the utility model is intended to propose a kind of well-flushing and increases liquid device.
A kind of well-flushing fluid increasing device described in the utility model, comprise body, upper part of body is provided with inlet opening, last inlet opening bottom is provided with fluid hole, be interconnected between last inlet opening and the fluid hole, the described inlet opening place of going up is provided with the feed liquor ball valve, and the feed liquor ball valve is movably arranged on the inlet opening place, described fluid hole place is provided with ball valve chamber, and ball valve chamber inside is provided with movable ball valve.
Preferably, the smallest cross-sectional diameter of described ball valve chamber is greater than the ball valve diameter.
Preferably, described feed liquor ball valve is arranged on the body by spring.
Preferably, described fluid hole bottom is provided with down inlet opening, is interconnected between described inlet opening down and the fluid hole.
A kind of well-flushing fluid increasing device described in the utility model, flushing fluid has increased the pumping power of oil well pump to the kill-job effect of oil reservoir and the pollution that after immersing oil reservoir oil reservoir is caused in the time of can avoiding traditional hot to wash, and reduces the pump leakage, increases liquid outlet quantity, improves pump efficiency.
Description of drawings
Fig. 1 is the half sectional view of the utility model embodiment 2;
1-goes up inlet opening among the figure; The 2-fluid hole, inlet opening under the 3-; 4-feed liquor ball valve; The movable ball valve of 5-.
The specific embodiment
Embodiment 1.
A kind of well-flushing fluid increasing device described in the utility model, comprise body, upper part of body is provided with inlet opening 1, last inlet opening 1 bottom is provided with fluid hole 2, is interconnected between last inlet opening 1 and the fluid hole 2, and the described inlet opening place of going up is provided with feed liquor ball valve 4, feed liquor ball valve 4 is arranged on the body by spring, described fluid hole 2 places are provided with ball valve chamber, and ball valve chamber inside is provided with movable ball valve 5, and the smallest cross-sectional diameter of ball valve chamber is greater than the ball valve diameter.
A kind of well-flushing fluid increasing device described in the utility model, be arranged on the bottom of oil well pump, during well-flushing, lay down the plug of oil well pump earlier, the flushing fluid after the heating flows in the well-flushing fluid increasing device through well head, hollow rod, feed liquor ball valve 4 is moved down by well-flushing action of hydraulic force compression spring, to fluid hole 2, movable ball valve 5 moves to the ball valve chamber bottom flushing fluid, returns out from oil pipe through last feed liquor orifice flow.Movable steel ball is downward, and movement can prevent effectively that flushing fluid from entering in the well, after well-flushing finishes, decompress(ion), steel ball under spring action from horizontal reset.
Embodiment 2.
Present embodiment is substantially the same manner as Example 1, and difference is that present embodiment is provided with inlet opening 3 down in fluid hole 2 bottoms, is interconnected between described inlet opening 3 down and the fluid hole 2.
During normal the oil pumping, the down stroke stage: it is inner that well liquid enters this device by following inlet opening 3, and movable ball valve 5 is up under well liquid percussion, and well liquid flows to fluid hole 2, enters the annular space of hollow rod and oil pipe then, finishes the process of a feed liquor; The upstroke stage: feed liquor ball valve 4 is downward, can effectively seal well-washing device fluid increasing device upper liquid.Simultaneously, along with finishing of upstroke, the well liquid that sucks during by down stroke is pumped into ground, finishes the process of a discharge opeing.In the whole pumping process, this device is divided into two parts up and down with the well liquid in the oil pipe, thereby has reduced the head of liquid on the oil well pump, has reduced design of string pipe gap leaking loss amount.Simultaneously, take out utmost point liquid with oil pump plunger piston, increase the pumping power of oil well pump, realized increasing the purpose that liquid is put forward effect.
