Description
Technical field
The present invention relates to a kind of oil gas field auxiliary agent technical field, in particular to a kind of overall process takes the low frictional resistance slippery water of sand
Fracturing fluid and its preparation method and application.
Background technique
Oil-gas Layer hydraulic fracturing (Hydraulic Fracturing), referred to as oil-gas Layer pressure break or pressure break, are one and change
The technology for making oil-gas Layer seepage characteristic is an important process measure of well production increment, water injection well stimulation, is to utilize ground
Face high pressure pump group, by high-viscous liquid to be formed about high pressure in shaft bottom immediately in the discharge capacity injection well more than formation absorption ability,
After this pressure is more than the shaft bottom nearby tensile strength of reservoir stress and rock, crack is formed in the earth formation, it will be with proppant
In liquid injection seam, extend seam forward, and fills out the liquid injected into well with proppant, and in fracturing process and referred to as press
Split liquid, fracturing fluid is the important component of fracturing technique, generally to the performance requirement of fracturing fluid: viscosity is high, and lubricity is good, filter
Vector is small, to by the fluid layer of pressure break, without blocking and damage, pollution-free to fluid mine, general fracturing fluid has aqueous fracturing fluid, oil
The types such as base fracturing fluid, emulsus fracturing fluid, foam fracturing fluid and acid-base fracturing fluid.
Currently, common fracturing fluid is mainly the fracturing fluid using guanidine glue and its modifier as the aqueous fracturing fluid of thickening agent
It is widely applied in each oil gas field, and achieves good effect of increasing production, but celebrate oil gas field " batch production " pressure break with long
The it is proposed of work pattern and Environmental Protection Situation are increasingly severe, it is desirable that aqueous fracturing fluid in addition to Low Damage, low frictional resistance, low cost,
Except the easy row of returning, easily continuous mixed feature, there is the characteristics of easy recycling, high recycling rate, also to return drain after reduction pressure
The amount of conserving water while to environment and soil pollution.
However it is existing using guanidine glue and its modifier as the fracturing fluid of thickening agent, since guanidine glue and its modifier have plant
The putrefactive disadvantage of glue and to return drain processing difficulty after breaking gel big, it is at high cost, reuse poor feasibility, thus with guanidine glue and
Its modifier is that the fracturing fluid of thickening agent is unable to satisfy current " batch production " construction requirement.
Summary of the invention
The present invention provides a kind of fracturing fluid, solves in the prior art using guanidine glue and its modifier as the fracturing fluid of thickening agent
