摘要:用液体石蜡、甲醇、乳化剂 B 和分散剂 TW60 制备乳化液,向乳化液中加入超分子聚合物稠化剂 BCG-1H,
搅拌均匀后制得浓缩稠化剂 HBCG。通过观察乳化液的稳定性和流动性对乳化液内相、分散剂进行优选,通过
正交实验对 HBCG 各组分用量进行了优化,最终确定 HBCG 组成为:26.9 g 液体石蜡、30.4 g 甲醇、2.4 g 乳化
剂 B、0.3 g 分散剂 TW60 和 40 g BCG-1H。通过溶解性能、耐温耐剪切性能、破胶性能以及残渣含量对 HBCG
的溶解性能及由其配制的压裂液各项性能进行了测试。结果表明,HBCG 溶解时间仅为 0.8 min,溶解过程中不
会产生“鱼眼”,可实现现场快速配制。配制的压裂液具有良好的耐温耐剪切能力,当 HBCG 质量浓度为 16 g/L
–1
时,在 170 ℃、170 s 条件下剪切 90 min,最终黏度稳定在 40 mPa·s 左右;在 95 ℃下支撑剂陶粒(20~40 目)
的悬浮时间长达 3.6 h,表现出优良的悬砂性能,4 h 内可彻底破胶,破胶液的表面张力较低(27.5 mN/m)、残
渣含量极低(9.80 mg/L),表现出良好的清洁特性。

Abstract: An emulsion was prepared with liquid paraffin, methanol, emulsifier B and dispersant TW60.
Then, supermolecular polymer thickener BCG-1H was added into the emulsion and mixed well, and a
thickener HBCG was prepared. The internal phase and dispersant of the emulsion were optimized by
observing the stability and fluidity of the emulsion. The dosage of each component of HBCG was optimized
through orthogonal experiment. Final HBCG was determined to be composed of 26.9 g of liquid paraffin,
30.4 g of methanol, 2.4 g of emulsifier B, 0.3 g of dispersant TW60 and 40 g of BCG-1H. The solubility of
HBCG was tested. Various properties of the fracturing fluid prepared from HBCG were characterized by
the solubility test, temperature and shear resistance test, glue breaking performance test and residue content
test. The results showed that the dissolution time of HBCG was only 0.8 min, and no fisheye was produced
in the dissolution process, which could realize the rapid preparation on site. The prepared fracturing fluid
had good temperature resistance and shear resistance. When the mass concentration of HBCG was 16 g/L,
the final viscosity of the fracturing fluid was stable at about 40 mPa·s after shearing for 90 min at 170 ℃
–1
and 170 s . At 95 ℃, the suspension time of fracturing propping agent, ceramsite (20~40 mesh) was as
long as 3.6 h, showing excellent suspended sand performance. The glue was broken completely within 4 h.
The surface tension of the glue breaking solution was low (27.5 mN/m) and the residue content was low
(9.80 mg/L), indicating that the fracturing fluid had good cleaning characteristics.
