Description
Technical field
The present invention relates to a kind of " water-water " height of the fluorine-containing modification of hydrophobic and oil repellent returns row, Low Damage slippery water fracturing liquid
It is drag reducer, belongs to oil gas field engineering chemistry agent applied technical field.
Background technology
In recent years, with the extensive exploration and development of unconventionaloil pool, the slippery water for the purpose of improving reservoir permeability
Pressure break receives more and more extensive concern.Slippery water refers to and a small amount of drag reducer and some other chemistry is added in clear water or saline
The working solution of auxiliary agent.This working solution injects underground in the way of high-voltage high-speed, and pressure break oil and gas reservoir improves permeability, so as to
Increase oil-production capacity.However, slippery water pressure break drag reducer has series of problems, the such as row's of returning poor performance, reservoir at present
Injure serious etc..There are some researches show that the post-fracturing oil gas daily output is significantly less than expection, and fracturing fluid selects improper caused storage
Layer injury is likely to the key factor for producing this phenomenon.
The hydraulic fracturing drag reducer reported in document at present is the equal of water-soluble macromolecule, such as polyacrylamide etc.
The Chinese invention patent application of polymers or copolymer, such as Publication No. CN103013488A and Publication No. CN102977877A.
Although this kind of drag reducer has high water solublity, its intermolecular strong interaction based on hydrogen bond, and and reservoir
The affinity on surface also tends to the consequence for causing the low row of returning and high reservoir damage.That is after pressure break, drag reducer macromole is inclined to
Property viscous flow in reservoir micro-fractures, block gas channel, reduce the oil gas daily output.
