The visco-elastic surfactant acid liquid system of the quaternary ammonium alkyl salt surfactant of base containing erucic acid, according to quality include 25%HCL,
5%VES, 3% corrosion inhibiter and 1% ferrous stability, remaining is water.
The process of the well construction, as acid solution is gradually reacted with formation rock, in the case where discharge capacity is stable, construction pump pressure
There is up-trend；Illustrate as the progress of acid-rock reaction, the reduction of acid strength, acid liquid viscosity increases automatically, cleaning acid solution rises
The effect turned to has been arrived, has been conducive to the uniform transformation of heterogeneous reservoir, the ability of the potential volume increase of reservoir can be given full play to.The Bowl
After acidfracturing treatment, increase production 23 times.
In summary, the visco-elastic surfactant acid liquid system of the quaternary ammonium alkyl salt surfactant of base containing erucic acid of the invention has excellent
Delay acid-rock reaction speed ability and turning function, can effectively prevent acid solution to hypertonic part occur fingering, improve acid
Operating distance is lost, and the migration of the clay minerals illite etc. can be suppressed, permanently effective fracture condudtiviy is kept.Also simultaneously
With excellent heatproof, anti-shearing and low friction performance, well depth can be met more than 6000m, HTHP of the temperature more than 200 DEG C
The acid fracturing operation of layer.Field experiment shows the visco-elastic surfactant acid system acid with the quaternary ammonium alkyl salt surfactant of base containing erucic acid
Pressing element has significant effect of increasing production.The visco-elastic surfactant acid system of the quaternary ammonium alkyl salt surfactant of base containing erucic acid is tested at the scene
With application more than 100 Kou Bowl, significant effect of increasing production is achieved.
The specific embodiment of the present invention is the foregoing is only, but the technical characteristic of the present invention is not limited thereto, Ren Heben
The technical staff in field is in the field of the invention, and the change or modification made all are covered among the scope of the claims of the present invention.
