    摘要:

    以二乙醇胺(DEA)、丙烯酸甲酯(MA)、三羟甲基丙烷(TMP)、顺丁烯二酸酐(MAH)为原料,合成了一种端羧基超支化大单体HPAE-C。并以HPAE-C、丙烯酰胺(AM)、丙烯酸(AA)以及2-丙烯酰胺基-2-甲基丙磺酸(AMPS)为单体,在水溶液中进行自由基聚合得到一种四元共聚物稠化剂PHPAE-C。通过FTIR和1HNMR对其结构进行表征。评价了超支化稠化剂的溶液性质和交联性能。结果表明,稠化剂质量浓度为3000 mg/L(剪切速率为7.34 s-1,25℃)时,溶液表观黏度可达846.7 mPa·s,升温至90℃时,黏度仍为570 mPa·s,并且在Na+质量浓度为6000 mg/L、Ca2+和Mg2+质量浓度为600 mg/L时表观黏度仍能达到300mPa·s以上,说明PHPAE-C具有良好的增黏、耐温、耐盐和抗剪切性能;在交联比m(聚合物水溶液)∶m(乙酰丙酮锆)=100∶0.06、交联温度为55 ℃、pH=5时交联效果最佳。并对交联效果最佳的压裂液进行了性能评价,结果表明,在120℃、170s-1下剪切80 min后,该体系的表观黏度可达到450 mPa·s左右,并且是一种具有良好悬砂、破胶性能的低伤害压裂液体系。

    Abstract:

    A carboxyl terminated hyperbranched macromonomer HPAE-C was prepared from diethanolamine (DEA), methyl acrylate (MA), trimethylolpropane (TMP) and maleic anhydride (MAH). And quaternary polymer thickener PHPAE-C was synthesized from HPAE-C, acrylamide (AM), acrylic acid (AA) and 2-acrylamide-2-methylpropanesulfonic acid (AMPS) by aqueous solution polymerization .The structure of PHPAE-C was characterized with FTIR spectrum and1H-NMR spectrum, and the major performance and crosslinking ability of PHPAE-C were evaluated. The results showed that the viscosity of thickener solution with the concentration of 3000 mg / L was 846.7 MPa·s (The Shear rate is 7.34 s-1, 25℃), when the temperature rose to 90 ℃, the viscosity was still 570 MPa·s, and when the concentration of Na+ is 6000 mg/L and the concentration of Ca2+and Mg2+ was 600 mg/L, the viscosity was still more than 300 MPa·s.The above data showed that PHPAE-C had good viscosity increasing, temperature resistance, salt resistance and shear resistance; The optimum conditions of crosslinking were as follows: the crosslinking ratio was 100∶0.06, the crosslinking temperature was 55 ℃ and pH = 5. The performance of the fracturing fluid with the best crosslinking effect was evaluated. It was obtained that the viscosity of the system was about 450 MPa·s after continuously shearing at 120 ℃ for 80 minutes, and it was a low damage fracturing fluid system with good sand suspension and gel breaking performance.
