Description
Technical field
It blocks water system the present invention relates to a kind of reusable drop, is mainly used for fine and close oil gas sandstone reservoir volume fracturing and changes
It makes.
Background technique
The low-pressure construction that the system that blocks water mainly realizes compact reservoir using the low frictional resistance effect of friction reducer, resistance-reducing yield drop
It is the key index of friction reducer.Currently, blocking water system friction reducer predominantly in polyacrylamide macromolecule for drop both at home and abroad
Polymer, wherein such friction reducer and can be subdivided into emulsion-type and two kinds of powder-type according to the difference of production and processing mode.Existing
In the work progress of field, powder-type friction reducer must be configured to aqueous solution using artificial or liquid equipment, this just gives fine and close storage
The massive hydraulic fracturing construction of layer brings inconvenience, as fracturing unit placing space is limited, flow container placing space is limited, Ren Yuanlao
Big, long construction period of intensity etc. before dynamic, and emulsion-type or Instant friction reducer at the scene in work progress discovery exist layering or
Caking phenomenon, properties of product are greatly reduced；Part drop blocks water, and sand carrying effect is poor, and scene need to improve pump note discharge capacity to make up system
Sand carrying effect cause a large amount of fracturing outlet liquid after Large Construction further, since the anti-hardness performance of polymer salt tolerant itself is poor
Cannot effective reuse, or using reuse after high price water treatment technology, the system is caused not to be well positioned to meet low cost development
Site operation demand.
Therefore, it develops that a kind of resistance-reducing yield is high, the row of helping performance is good, salt resistant character is good, construction and reuses simple process
Reusable drop block water system system, to solve prior art problem, and will have good popularization and application foreground.
Summary of the invention
In order to overcome the problems, such as that existing resistance-reducing yield is low, the row's of helping performance is poor, salt resistant character is poor and cannot recycle, the present invention
It proposes a kind of reusable drop to block water system, is liquid it is an object of the present invention to friction reducer and regulator, increases
The thick time is less than 10 seconds, it can be achieved that online mixture.
The second object of the present invention is of the invention under the normal temperature condition of ground, 1.3~30mPas of fracturing fluid viscosity, and
It can be according to construction demand, the instantaneous conversion of canbe used on line fracturing fluid viscosity.
The third object of the present invention is that the present invention can use clear water or salt content and match in the drain of returning of 100000ppm
Liquid, and without removing calcium ions and magnesium ions, resistance to bacterium it is anti-it is rotten, recycling technique is easier.
The fourth object of the present invention is that the system that blocks water provided by the invention that drops is faintly acid to neutrality, avoids pressing effectively
While splitting the corrosion of equipment and down-hole string, can effective acid etching reservoir carbonate mineral, injury rate is lower, and effect of increasing production is more
Obviously.
The technical solution adopted by the present invention is：
One kind is reusable to drop the system that blocks water, it is formulated in following mass component ratio：
Friction reducer：0.2 part~1.5 parts；
Regulator：0~1 part；
Surplus is with liquid water.
It is formulated in following mass component ratio：
Friction reducer：1 part；
Regulator：0.5 part；
Surplus is with liquid water.
The friction reducer is 40~55% surfactants, 4~15%, 10~20% solvent of salicylic acid, and surplus is water.
The solvent is one or more mixtures of methanol, isobutanol, ethylene glycol, glycerol.
The surfactant is dodecyl tertiary amine oxide, oleamide diemethylamine, erucyl amide propyl two
One of methylamine or a variety of mixtures.
The regulator is acidity.
The liquid water of matching is the fracturing outlet liquid of clear water or salt content in 100000ppm.
Fracturing outlet liquid of the salt content in 100000ppm is to drop to block water to return drain, corruption or uncorrupted
Guanidine glue returns drain, putrid and deteriorated or uncorrupted EM series returns drain or stratum pumping water or output water.
A kind of recycling drop prepared blocks water as faintly acid to neutrality.
The drop blocks water online mixture when site operation, prepares drop and blocks water the system thickening time lower than 10s, and online mixture
1.3~the 30mPas of system viscosity that blocks water drops.
Beneficial effects of the present invention are：
In the present invention, a kind of recycling drop blocks water by forming following weight percentage components：Friction reducer：0.2 part~1.5
Part；Regulator：0~1 part；Surplus is with liquid water.Friction reducer and regulator are liquid, thicken the time less than 10 seconds, it can be achieved that
Online mixture.
In the present invention, a kind of recycling drop resistance-reducing yield that blocks water reaches as high as 70% or more.
In the present invention, a kind of recycling drop system that blocks water is faintly acid to neutrality, is effectively avoiding fracturing unit and well
While the corrosion of lower tubular column, can effective acid etching reservoir carbonate mineral, injury rate is lower, and effect of increasing production becomes apparent from.
In the present invention, a kind of recycling drop blocks water under the normal temperature condition of ground, 1.3~30mPas of fracturing fluid viscosity,
And it can be according to construction demand, the instantaneous conversion of canbe used on line fracturing fluid viscosity.
In the present invention, a kind of recycling drop, which blocks water, can use the drain of returning of clear water or salt content in 100000ppm and matches
Liquid, and without removing calcium ions and magnesium ions, resistance to bacterium it is anti-it is rotten, recycling technique is easier.
In the present invention, a kind of recycling drop block water anti-dilative up to 85% or more, and after system pressure the row of helping is functional.
In the present invention, a kind of recycling drop system of blocking water can be avoided effectively during conventional surfactants construct at the scene
When not enough causing Efficient Adhesive Promotion undesirable due to matching liquid water salt ionic concentration or be fresh water with liquid water, KCL need to be manually prepared in advance
The drawbacks of aqueous solution.
It is further detailed below with reference to attached drawing.
