摘要 目前常规清洁压裂液主剂多为黏弹性表面活性剂十六(或十八)烷基三甲基氯化铵,该类清洁压裂液的抗温能力较差(一般低于60℃)。基于高碳链芥酸的季铵盐型表面活性剂(JS-VES)具有良好的耐温能力,以JSVES为主剂研制高碳链芥酸型清洁压裂液,其配方为(质量分数)(0.80%JS-VES+0.68%NaSal+2.60%KCl+0.40%Na_2S_2O_3),和常规清洁压裂液体系的性能进行对比。结果表明,高碳链芥酸型清洁压裂液体系(25℃、170s^(-1))表观黏度为25mPa·s,具有良好的耐剪切性能,在静态悬砂试验中可满足悬砂要求,具有良好的破胶能力(2mPa·s)和耐温能力(80℃)。 At present,most of the main agent of conventional clean fracturing fluids are viscoelastic sixteen(or eighteen)alkyltrimethylammonium chloride,which has poor temperature resistance(generally less than 60℃).The quaternary ammonium salt type surfactant(JS-VES)based on high carbon chain erucic acid has good temperature resistance.In this paper,a high-carbon erucic acid-type clean fracturing fluid(mass fraction)(0.80%JS-VES+0.68%NaSal+2.60%KCl+0.40%Na 2S 2O 3)was developed with JS-VES as the main agent,and compared with the conventional clean fracturing fluid system performance.The high-carbon erucic acid-type clean fracturing fluid system(25℃,170 s-1)has an apparent viscosity of 25 mPa·s.It has good shear resistance,and can meet the requirements of suspended sand in the static suspension of sand,with a good breaking capacity(2 mPa·s)and temperature resistance(80℃).
