Abstract
The invention discloses a blockage relieving device for an oil-water well, which comprises a barrel, a piston, a spring device, jet holes and a bolt. The upper end of the barrel is connected with an oil tube. The piston and the spring device are arranged in an inner cavity of the barrel. The outer wall of the barrel is provided with a plurality of jet holes. The blockage relieving device for the oil-water well has a simple structure and is convenient to connect. A special tool is not required. The blockage relieving device for the oil-water well is simple to construct, has low cost and is easy to popularize.
Description
Technical field
The present invention relates to a kind of de-plugging equipment of oil field machinery oil well, be specifically related to a kind of plug removal in oil and water well device.
Background technology
Along with the oil field gets into development late stage, stratum condition worsens, the water injection well overflow, shake out serious, survey transfer be hampered, the ever more important that the work of water injection well regular maintenance well-flushing is become frequently appears in problem wells such as packer inefficacy.In the prior art; The hot-washing wax remover device that a kind of oil field machinery oil well is arranged; It adopts sleeve pipe to connect the well-flushing pipeline, and flushing fluid is from being circulated to the oil reservoir position between the ring set, through the standing valve of oil well pump; Turn back in the ground flow from oil pick-up tube again, reach the purpose of removing sand, wax, salt and other dirts.Under the extremely low situation of formation pressure, a part of flushing fluid can get into oil reservoir, pollutes.The production fluid level that oil well after heat is washed will return to before heat is washed needed for 1 ~ 2 week usually; Even not fuel-displaced after heat is washed, so that need just can resume production after the operation.In recent years, real estate, low pressure oil well increase year by year, owing at the bottom of the strata pressure, in the process of cleaning, have the part flushing fluid to get into the stratum, cause formation damage, influence the oil well ordinary production, also can cause the pollution of environment simultaneously.
Summary of the invention
In order to solve the problem that exists in the background technology, the invention provides a kind of simple in structure, easy for installation, energy-conserving and environment-protective, plug removal in oil and water well device cheaply.
The technical scheme that the present invention adopts is:
A kind of plug removal in oil and water well device comprises cylindrical shell, piston, spring assembly, jet orifice, bolt, and said cylindrical shell upper end connects oil pipe, and piston and spring assembly are installed in the cylinder lumen, and said cylinder body outer wall is provided with a plurality of jet orifices.
Cylinder body outer wall below when said jet orifice is positioned at the piston extension state.
The invention has the beneficial effects as follows:
1) present device simple in structure, easy for installation, be convenient to constructing operation;
2) plugging removal effect of the present invention is good, and it is big to handle depth of stratum;
3) the present invention constructs simply, and energy-conserving and environment-protective, operating expenses are low, is easy to promote.
Below in conjunction with Figure of description the present invention is done further description.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
1. jet orifice 2. pistons 3. springs 4. cylindrical shells 5. bolts
The specific embodiment:
A kind of plug removal in oil and water well device as shown in Figure 1; Comprise cylindrical shell 4, spring assembly 3, piston 2, jet orifice 1, bolt 5; Said cylindrical shell 4 upper ends connect oil pipe, and piston 2 is installed in cylindrical shell 4 inner chambers with spring assembly 3, and said cylinder body outer wall is provided with a plurality of jet orifices 1.Cylindrical shell 4 outer walls below when said jet orifice 1 is positioned at the piston extension state.
During the work of this device, this device upper end is connected on the oil pipe, is lowered into the required target zone that de-plugging is handled that carries out; The liquid that pumps into through external power arrives low frequency hydraulic vibration generator through oil pipe, and the fluid pressure on piston top acts on piston 2, makes it descending; Jet orifice 1 is communicated with upper liquid stream when piston 2 descending certain distances; Flow is impacted borehole or oil reservoir from jet orifice 1 ejection at a high speed, and the stratum is imposed punching press.Simultaneously, owing to piston top flow is communicated with the oil-water well annular space through jet orifice 1, thereby cause piston top head of liquid to reduce, piston is up under the effect of lower springs 3, closes jet orifice 1.In this process,, concerning the stratum, experienced the counter motion process of a dilatational wave, formed the pressure pulse concussion so repeatedly, reached the purpose of oil layer unblocking because bottom pressure reduces by counter the spitting in the well of formation blockage thing of shake pine.
Though the present invention describes with reference to aforesaid specific embodiment; But those skilled in the art will be appreciated that; Above embodiment only is in order to explanation the present invention rather than restriction the present invention, as long as in the scope of in connotation scope of the present invention, the variation of the foregoing description, claims that modification all should fall into the application being asked for protection.
