Technical field
The utility model relates to be acidified field, and in particular to ground liquid equipment in a kind of acid stimulation.
Background technique
Acidification is a kind of measure of intensified oil reduction (EOR), is an effective technology of well production increment, injection well augmented injection
Measure.Its principle is the dissolution and corrosion by acid solution to tamper in rock cement or formation pore, crack etc., extensive
Permeability that is multiple or improving formation pore and crack.Acidification can be divided into pickling, matrix acidifying and fracture acidizing according to technique difference
(also referred to as acid fracturing).Pickling is to inject a small amount of acid solution in pit shaft, removes acid-soluble particles and drilling cuttings and dirt etc. in pit shaft eyelet, and
Dredge preforation tunnel.Matrix acidifying is that acid is being injected stratum lower than under rock rupture pressure, extensive by the corrosion of acid solution
Permeability that is multiple or improving oil reservoir near wellbore larger range.Acid fracturing (acid fracturing) is will in the case where being higher than rock rupture pressure
Acid injection stratum, forms crack in stratum, forms high flow conductivity by the uneven corrosion of acid solution fracture wall surface substance
Crack.Acidizing treatment using such as cementing truck, pump truck one kind Construction traffic, by acidic aqueous solution (e.g., hydrochloric acid, hydrofluoric acid,
Organic acid) injection stratum.The acid solution of injection can dissolve formation rock or cement, to increase in-place permeability, make oil gas
Output, driven water-replacing injection are more convenient.In acidizing treatment, in order to improve acidizing effect, it can be infused using polymer viscous acid
Enter, organic retardant injection, become sticky acid acidification, viscoelastic surfactant acidification etc. new processes.It is needed during acid stimulation
A large amount of acidifying solutions are persistently injected to stratum, it is high for ground storage request, greater number of pump is mostly used in the prior art
Vehicle etc. matches liquid in advance, is injected after then arriving at scene.This mode expends vast resources, need more pump truck or storage tank into
The configuration in advance of row acid solution and storage, engineering cost are higher.

Value can all be shown on a display screen.When the utility model is specifically used, raw material is added into mixed flow container by each charge pipe
Acid solution is configured, acid solution after mixing enters in buffer reservoir and acid filling tank while being stored, logical first when needing acid filling
The solution that charge pump extracts in acid filling tank is crossed to carry out using while new acid solution being initially configured in mixed flow container, when in acid filling tank
Solution when soon being exhausted, open the valve between buffer reservoir and acid filling tank, the solution stored in buffer reservoir filled into
In acid filling tank.Configured acid solution new in mixed flow container is imported again spare in buffer reservoir.Each Ph tester in buffer reservoir
It monitors the Ph value of different liquid levels and shows on a display screen, staff can intuitively see different liquid in buffer reservoir
The Ph value of position height judges whether acid solution has phenomena such as sedimentation is layered in buffer reservoir during acid filling with this, thus
Reconfiguring occurs directly passing through bypass pipe when sedimentation layering and exhausting in acid solution, with ensure to inject the performance of acid solution on stratum stablize it is equal
It is even, improve acidizing effect.Turbulent device is used to ensure that the solution into acid filling tank to be in turbulent condition, avoids the formation of laminar flow layering
Phenomenon.Turbulent device includes several arc panels for being fixed on inboard wall of tube body, and several arc panels are distributed in tubular body along helix,
The solution for entering acid filling tank is upset by several arc panels and is broken up, it is ensured that solution is in turbulent condition, while can guide again
Flows downward.
Preferably, the width of the arc panel is the 1/10 of internal diameter of tube body.Arc panel is avoided to make the normal latus rectum of tube body
Situations such as leading to arc board ends pressure difference at interference appearance, width are that the arc panel of 1/10 internal diameter of tube body also can effectively upset pipe
Body marginal portion thoroughly prevents the wind that the utility model forms laminar flow to reduce interference of the tube wall viscous force to flow regime
Danger.
Preferably, the buffer reservoir is equal with the volume of acid filling tank.
The utility model compared with prior art, has the following advantages and benefits:
