Description
Technical field
The present invention relates to the water base of oil field oil reservoir fracturing reform field more particularly to a kind of fine and close oil-gas reservoir low damage fracture
Fracturing fluid.
Background technique
Cellulose fracturing fluid has an application in Dagang Oilfield and Yumen Oilfield early stage, but because of cellulose dissolution slowly, difficult crosslinking,
The disadvantages of salt tolerance is poor, thickening effect is bad, residue is big to formation damage, does not obtain lasting development.
There are two types of developing direction for previous cellulose fracturing fluid tool, first is that fine by the way that conventional cellulose such as carboxymethyl is added
Dimension element, hydroxyethyl cellulose have the function that increasing apparent viscosity takes sand, hands over cellulose solution second is that screening dedicated crosslinking agent
If connection forms gel, but solid-carrying performance and endurance of cutting can be poor, are not suitable for big sand than construction.Also having will cellulose modified rear friendship
Connection forms the fracturing fluid of netted frozen glue, although residue, solid-carrying performance are significantly improved compared with traditional fibre element fracturing fluid, temperature tolerance
Can be poor, it is only applicable to 70 DEG C or less hole conditions substantially, it is single although increased fiber element gelatin concentration can meet 130 DEG C of hole condition constructions
Base fluid apparent viscosity is very big, and site operation frictional resistance is high, constructional difficulties, and fracturing fluid is with high costs, can not large-area applications.
Summary of the invention
It is an object of that present invention to provide a kind of easily preparation, low frictional resistance, Low Damage, low cost, safety and environmental protection it is instant without residual
Slag modified cellulose fracturing fluid and preparation method thereof.
It is described in order to solve the above-mentioned technical problems, the present invention provides a kind of instant no residue modified cellulose fracturing fluid
The constituent of fracturing fluid is matched by following mass parts:
MH-028 pressure break acidic thickener modified cellulose 0.2-0.6 parts by weight；
MH-031 pressure break stable regulation agent Triaethanolamine class 0.1-0.4 parts by weight；
MH-016 fracture acidizing cleanup additive 0.2-0.6 parts by weight；
MH-032 pressure break crosslinking agent modified cellulose zirconyl hydroxy class 0.2-0.5 parts by weight；
MH-030 crosslinking accelerator hydroxyacetic acid class 0.2-0.7 parts by weight；
Ammonium persulfate 0.003-0.001 parts by weight；
Water 99.1-97.2 parts by weight.
Further, the MH-028 pressure break is anionic grafting chemical modification hydroxyl second with acidic thickener modified cellulose
Base cellulose, molecular weight 4000000-7000000.
Further, the MH-031 pressure break is Triaethanolamine, carbon with the ingredient of stable regulation agent Triaethanolamine class
Sour sodium, sodium thiosulfate, glycerine, water；By weight percentage --- Triaethanolamine 20-2%, sodium carbonate 10-1%, sulphur
Sodium thiosulfate 10-1%, glycerine 40-10%, water 0-28%.
Further, the MH-016 fracture acidizing is alkyl glycosides, fluorine-containing surfactant, nonyl with cleanup additive ingredient
Phenol polyethenoxy ether, fatty alcohol polyoxyethylene ether, neopelex, water；Alkyl glycosides 10- by weight percentage
2%, fluorine-containing surfactant 6-0.5%, nonylphenol polyoxyethylene ether 10-2%, fatty alcohol polyoxyethylene ether 10-3%, 12
Sodium alkyl benzene sulfonate 20-5%, water 44-12.5%.
Further, the MH-032 pressure break with crosslinking agent modified cellulose zirconyl hydroxy constituents be lactic acid, zirconium oxychloride,
Aluminium chloride, glycerine, ethylene glycol, triethanolamine, citric acid, acetic acid, sodium gluconate, water；Lactic acid 15- by weight percentage
5%, zirconium oxychloride 8-2%, aluminium chloride 8-2%, glycerine 10-5%, ethylene glycol 10-5%, citric acid 10-2%, acetic acid 13-
3%, sodium gluconate 10-1%, water 16-70%.
Further, the MH-030 crosslinking accelerator hydroxyacetic acid constituents are formic acid, acetic acid, lactic acid, water；With weight
Percentage calculates formic acid 10-1%, acetic acid 15-2%, lactic acid 12-2%, water 61-95%.
The present invention separately provides a kind of preparation method of instant no residue modified cellulose fracturing fluid, comprising the following steps:
The MH-028 pressure break acid of 0.2-0.6 parts by weight is added in S1 into 99.1-97.2 parts by weight water under agitation
Property thickener modified cellulose, stir 5 minutes, obtain cellulose aqueous solution；
S2 promotees MH-032 pressure break crosslinking agent modified cellulose zirconyl hydroxy class 0.2-0.5 parts by weight, MH-030 crosslinking
Into agent hydroxyacetic acid class 0.2-0.7 parts by weight, MH-031 pressure break stable regulation agent Triaethanolamine class 0.1-0.4 parts by weight,
MH-016 fracture acidizing cleanup additive 0.2-0.6 parts by weight, water 99.1-97.2 parts by weight, it is successively mixed in proportion, it prepares and strikes a bargain
Join liquid；
S3, crosslinked fluid is added in cellulose aqueous solution by crosslinking ratio proportioning pump in pressing crack construction process, ammonium persulfate
0.003-0.001 parts by weight are added in the form of dry add, and netted frozen glue is formed after being stirred, and it is modified to be prepared into instant no residue
Cellulose fracturing fluid.
Compared with prior art, beneficial effects of the present invention:
1, modified on the basis of traditional hydroxyethyl cellulose to be grafted novel crosslinked group, change cellulose molecular structure and divides
Son amount, make the performance of modified cellulose with it is significantly different before modified, lower than 160 DEG C reservoir fracturing demands can be met.Folk prescription pressure
The significant decrease of liquid cost is split, it is close with your fracturing fluid price of conventional guanidine, it suits large area to popularize and applies.
2, the fracturing fluid system has and is crosslinked under instant, acid condition, easy preparation, low frictional resistance, Low Damage, low cost, peace
The features such as loopful is protected.
3, it is big to efficiently solve the problems, such as that conventional fracturing fluid residue height injures compact reservoir, changes traditional fibre element pressure
Split the disadvantages of liquid dissolution is slow, hardly possible is crosslinked, salt tolerance is poor, thickening effect is bad, residue is big to formation damage.It is preferred that dedicated
Medicament is used in combination with modified cellulose, and the disadvantage of traditional fibre element is preferably minimized, obtains the performance of fracturing fluid excellent
Change.
