Technical field
The invention belongs to fracturing fluid technical fields, and more specifically more particularly to a kind of clean fracturing fluid dedicated stream helps again
Agent.
Background technique
Fracturing fluid refers to the heterogeneous unstable chemical system formed according to a certain ratio by multiple additives, is to oil gas
Layer carries out the working solution used when fracturing reform, its main function is that the high pressure for forming ground installation is transmitted in stratum,
So that formation fracture is formed crack and conveys proppant along crack.
The process of oil formation hydraulic fracturing is that will be had using the pump of high-pressure large-displacement using the principle of liquid pressure transmission on ground
There is the liquid (normally referred to as fracturing fluid) of certain viscosity, is injected with being greater than the pressure of absorbability of oil reservoir to oil reservoir, and make
Well cylinder pressure gradually rises, so that high pressure has been suppressed in shaft bottom, when this pressure is greater than the crustal stress and formation rock near the borehole wall
Tensile strength when, just near shaft bottom stratum generate crack: continue injection have proppant load fluid, crack extends forward
And fill out with proppant, crack closure is on proppant after closing well, so that being formed near the shaft bottom in stratum has certain dimensioning
Very little and high flow conductivity sand packed fracture, is that well achievees the purpose that increasing yield and injection.Common proppant has quartz sand, haydite etc..
Fracturing fluid is very popular, wherein flowing multiple auxiliary agent is important ingredient in clean fracturing fluid, but traditional stream is multiple
