Proposition and the Environmental Protection Situation of celebrating oil gas field " batch production " fracturing work pattern are the severeest, it is desirable to water base pressure
Split liquid in addition to there is Low Damage, low frictional resistance, low cost, the easily row of returning, easily continuously mixture feature, also
Having easily recovery, the feature that recycling rate of waterused is high, to return discharge opeing to environment and soil pollution after reducing pressure
While the amount of conserving water.
But during using guanidine glue and modifier thereof as the thickening agent of fracturing fluid, guanidine glue and modifier thereof have plants
The putrefactive shortcoming of thing glue, after frozen glue relies on chemical crosslinking to be formed, returns discharge opeing intractability big after breaking gel,
Cost is high, reuses poor feasibility, so during using guanidine glue and modifier thereof as the thickening agent of fracturing fluid
Environmental protection pressure can not be alleviated and " batch production " construction requirement cannot be met.
Summary of the invention
The present invention provides a kind of fracturing fluid thickener, solves in prior art and makees with guanidine glue and modifier thereof
