Abstract
The utility model discloses a hydraulic blocking removal spraying stick for an oil-water well. Hydraulic impact blocking removal is performed on a stratum according to acidification measures of the oil-water well. The hydraulic blocking removal spraying stick is particularly suitable for blocking removal of the oil-water well with a plurality of layers of long well sections. The hydraulic blocking removal spraying stick comprises a sprayer body, wherein an end cover is connected to the bottom of the sprayer body; a bottom nozzle mounting hole is formed in the center of the end cover; and a body nozzle mounting hole is spirally formed around the sprayer body. A nozzle is arranged at the bottom of the spraying stick, and a second nozzle is spirally arranged around the sprayer body, so that the treatment range is expanded. The nozzle on the sprayer body is arranged according to a spiral line; meanwhile, another nozzle is also arranged under the bottom of the spraying stick, so that the problem of relatively small treatment range in a vertical direction in a well barrel because the nozzles are arranged on the same plane is solved; and different types of nozzles can be replaced on the sprayer body according to different treatment requirements.
Description
Technical field
The utility model relates to the downhole tool of petroleum industry, and particularly a kind of plug removal in oil and water well jetting rod cooperates oil-water well acidifying measure, and hydro-impact broken down is carried out on the stratum, is particularly useful for the plug removal in oil and water well of multilayer long well section.
Background technology
The high water-cut development period in the oil field after the oil-water well long-term production, is prone to have problems such as obstruction, fouling, causes oil well to fall product, well water filling difficulty to a certain extent.The long or multilayer oil-water well for perforated interval; Adopt conventional acid soak, generally squeeze measure such as acid; There are problems such as plug removal radius is little, acidifying is inhomogeneous, main at present employing hydrajet tool, and cooperate the acidifying measure; Through hydraulic blow power and acid corrosion action, to realize even acidification to dispel block to each interval.Still have following problem at the scene in the actual application: 1, the hydrajet tool nozzle arrange the position almost in one plane, the process range of vertical direction is less in pit shaft.2, when handling than long well section, need repeatedly play the lower tubular column adjustment process points degree of depth, or round-the-clock up and down tubing string, cause that execute-in-place is loaded down with trivial details, labour intensity is bigger.3, because the process points position is artificial control, the partial wells section handle less than or the processing time can't guarantee, do not reach the effect of uniform treatment.The scene needs a kind of hydrajet tool that is applicable to multilayer long well section plug removal in oil and water well.
Summary of the invention
The purpose of the utility model provides a kind of plug removal in oil and water well jetting rod, overcomes defective of the prior art, optimizes the layout of nozzle on head body, makes it adapt to the demand of long well section hydraulic blow acidification to dispel block, simplifies procedures, and guarantees construction effect.
The useful novel technical solution of this reality is: a kind of plug removal in oil and water well jetting rod comprises head body, connects end cap in its bottom, at the center of end cap the bottom nozzle installing hole is set, and around the head body spiral body nozzle installing hole is set.Nozzle has been installed in bottom in spray wands, around the head body spiral nozzle is set, and has enlarged process range.
Compared with prior art the utlity model has following useful effect:
1, the nozzle on the head body is arranged according to helix, simultaneously in the bottom of the utility model, a nozzle also has been installed under promptly, has avoided nozzle is installed in vertical direction process range problem of smaller in the pit shaft that causes on the plane;
2, abandoned the defective that this kind tool is in the past only installed the direct projection flow nozzle; Make full use of that rotating jet nozzle processing area is big, pulsing jet and the strong characteristic of cavitation jet impact effect; Nozzle adopts the modularized design of direct projection flow nozzle, rotating jet nozzle, pulse jet nozzle and cavitation jet nozzle, can on head body, change different types of nozzles flexibly according to different processing demands;
3, can control the rotary speed of the utility model comparatively accurately through the viscous liquid of filling different viscosities in speed control.
4, the head body that is lengthened out of the process points position on stratum is included, need not artificial control, makes to handle the well section and be guaranteed with the processing time, handles evenly, can increase work efficiency the assurance treatment effect.The length of lengthening head body, according to the various nozzles that stratum needs spiral is provided with, efficiently solve de-plugging needs of long well section Different Strata, need not repeatedly to rise again lower tubular column and adjust the process points degree of depth, or round-the-clock up and down tubing string.Only need progressively upper lifting pipe post, simple to operate, alleviated working strength of workers.
5, according to the needs of different well segment length, the length of design sprinkler body, the various nozzles of screw arrangement, when making the utility model be used for shorter well section, its hydraulic blow is handled more even, and effect is more obvious.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to accompanying drawing, a kind of plug removal in oil and water well jetting rod comprises head body 3, and head body 3 is connected with the axis of rotation 5 of damper.Speed control 7 is housed in the damper body 6; The viscous liquid that annotate different viscosities can for speed control 7 can be controlled the rotary speed of axis of rotation 5 comparatively accurately; Lubricating grease and butter mixture such as the filling different proportion; Can rotary speed be adjusted to per minute 20～100 changes, and regulates the speed of the shower nozzle that is connected with damper with this.The bottom of head body 3 connects end cap 2, at the center of end cap 2 bottom nozzle installing hole 1 is set, and around head body 3 spirals body nozzle installing hole 4 is set.Because it is unified that the screw thread of nozzle is installed in bottom nozzle installing hole 1 and the body nozzle installing hole 4, can change different types of nozzles as required at any time, can changes in the bottom nozzle installing hole 1 rotating jet nozzle, impulse jet nozzle or cavitating nozzle are installed.The nozzle of different types of nozzles or same type can be installed in the body nozzle installing hole 4 of spiral setting,, the rotating jet nozzle be installed preferably for guaranteeing the treatment effect of adjacent nozzles.As when the nearly well de-plugging such as fouling of pit shaft wall and sand screen obstruction, can on head body 3, only arrange the direct projection flow nozzle is installed, can satisfy the demand.If when carrying out the deep processing, then can arrange the installation different types of nozzles, like impulse jet nozzle, direct projection flow nozzle or cavitating nozzle.Perhaps arrange the nozzle that same type is installed simultaneously, like direct projection flow nozzle, impulse jet nozzle and cavitating nozzle.The length of head body 3 is arranged between 200mm～800mm.Can be according to the needs of different well segment length, change the design length of head body 3, make the utility model seriation, as with the Design of length of head body 3 at 200mm, 300mm, 550mm, 700mm or 800mm or the like.
