Description
Technical field
The present invention relates to the preparation methods of a kind of fracturing fluid and the fracturing fluid.
Background technique
Pressure break refers to (to be injected fracturing fluid into oil/gas well and forms high pressure) using hydraulic action, and oil-gas Layer is made to form crack
A kind of method.Its main function is the percolation ability in order to increase oil gas, improves oil and gas production.Fracturing fluid (fracturing
Fluid) be hydraulic fracturing transformation oil-gas Layer during working solution, play transmitting pressure, formation and extend crack, carry support
The effect of agent.Fracturing fluid and its performance are an important factor for influencing pressure break success or failure, this factor is more prominent for massive hydraulic fracturing
Out.Can fracturing fluid and its performance be to have close pass to produce a sufficient size, the sand packed fracture of enough flow conductivities
System.In the general expenses of pressing crack construction, fracturing fluid will account for 1/2 or more, and the fracturing fluid using appropriate performance is also to improve
The important channel of pressure break economic benefit.Good fracturing fluid must have following performance requirement:
(1) leak-off is few: this is the important performance for making slit, wide seam.The leak-off of fracturing fluid depends primarily on its viscosity
With wave making machine, then leak-off is few for viscosity height.Fluid loss additive is added in fracturing fluid can improve wave making machine, greatly reduce filter loss.
(2) it is strong to hang sand ability: the outstanding sand ability of fracturing fluid depends primarily on viscosity, as long as fracturing fluid has sufficiently high glue
Degree, sand can suspend completely, this is very favorable to distribution of the sand in seam.
(3) frictional resistance is low: the frictional resistance of fracturing fluid in the duct is smaller, then using come seam under conditions of plant capacity is certain
Effective power it is more.The excessively high utilization efficiency for not only reducing equipment of frictional resistance, or even limited since well head pressure is excessively high
Construction.
(4) thermal stability and anti-shear stability: guarantee that liquid cannot be since temperature raises or under mechanical shearing effect
And viscosity is greatly lowered.
(5) compatibility: fracturing fluid contacts after entering stratum with the rock forming mineral in stratum, should not rise and be unfavorable for oil infiltration
Physically or chemically reaction, such as not cause clay swell or occur precipitating and block stratum.The requirement of this compatibility is
It is very important, it is often ineffective after some low permeability formation pressure breaks, caused by having partly cause precisely due to compatibility is bad.
(6) break glue quickly, thoroughly: guarantee after fracturing fluid construction can the quick row of returning, raising construction efficiency.
(7) residue content is low: reducing injury of the fracturing fluid residue to stratum.
(8) source of goods is extensively convenient for preparing, and moderate cost is economically practical.
Recently as the exploitation upsurge of shale gas, the research of formula and preparation for hydraulic fracturing is relatively more, research
In terms of hot spot is concentrated mainly on the research of various pressure break medicaments and integral formula.As CN1869149A proposes a kind of high density pressure
Liquid is split, can be used for the exploitation of ultradeep well.CN102676146A proposes a kind of super guanidine gum fracturing fluid, is able to satisfy high temperature, low
