By introducing polymer molecular chains composed of acrylamide(AM),2-acrylamido-2-methylpropanesulfonic acid(AMPS),N-vinylpyrrolidone(NVP),and diallyl dimethyl ammonium chloride(DADMAC) into the hyperbranched monomer pentaerythritol triallyl ether(PETAE),we developed a hyperbranched fracturing fluid thickener HTB-1.Moreover, we characterized the structure of HTB-1,and evaluated its comprehensive performance.The results show that the molecular structure of HTB-1 meets the design expectations, with a viscosity-average molecular weight of 206 717.The hyperbranched structure facilitates HTB-1 to easily form a stable three-dimensional network structure in aqueous solution, endowing it with good temperature-resistance and salt-tolerance.The apparent viscosity of 0.6% HTB-1 aqueous solution is 81.0 mPa·s at 170 s-1 and 200 ℃,and is 86.3 mPa·s at 25 ℃ and a salinity of 100 000 mg·L-1,which can meet the construction conditions of high temperature and high salinity.After gel-breaking of 0.6% HTB-1 aqueous solution, the residue content is only 42.7 mg·L-1,the surface tension is only 22.7 mN·m-1,the anti-swelling rate is higher than 70%,and the average permeability recovery value of the core after contamination is 88.65%,indicating good reservoir protection performance, which is conducive to the efficient exploitation of tight oil reservoirs.
