The preparation method of the thickener is：By the chain alkyl polyoxyethylene ethyl propylene acid esters and 2- aminobenzenes of formula ratio
Phenol -4- sodium sulfonates are added in the ethyl alcohol of formula ratio, are stirred evenly, and the clear water for then adding in formula ratio is uniformly mixed.
A kind of application method of the acidproof thickener of surfactant, it is characterized in that：It is as follows：
The first step：Configure stable sticky acid solution；
Second step：Service shaft well head is opened, which is pumped into underground by fracturing unit truck；
3rd step：Closing well 30-90min after the end of job, treating sticky acid solution, the reaction was complete in reservoir；
4th step：Well head is opened, controls open flow；
5th step：Construction terminates.
The first step：Configure stable sticky acid solution；It is 10%~25% to take the thickener and mass percent concentration
It is stirred evenly after mixed in hydrochloric acid, forms sticky acid solution；Wherein, thickener is with hydrochloric acid mass percent：Thickener is 3%-
8%, surplus is hydrochloric acid.
It is an advantage of the invention that：The present invention is one using the sticky acid solution that the acidproof thickener of surfactant is formed with hydrochloric acid
The low frictional resistance of kind breaks glue, the Low Damage system without residue automatically, and compared with prior art, beneficial effects of the present invention are shown：
（1）Acid liquor thickener is liquid, and convenient and efficient with hydrochloric acid mixture, bodying velocity is fast, and acid liquor thickener is mixed with hydrochloric acid
1-2min can be thickened the viscosity for reaching stable after closing uniformly, and viscosity is more than 30mPa.s, and temperature resistant capability is more than 100 DEG C；
（2）It is low with the sticky acid solution frictional resistance that hydrochloric acid is formed using the acidproof thickener of surfactant, operation pressure is reduced, is carried
The acidifying correctional effect of high reservoir；
（3）After construction, sticky acid solution breaks glue automatically in shaft bottom, breaks adhesiveness and is less than 5mPa.s.
