摘要:
为弥补常规压裂液破胶困难、残留多或黏度低、用量大等缺点,将疏水改性羟丙基瓜尔胶与双子表面活性剂进行交联复配,制得1种疏水聚合物/表面活性剂复合压裂液,从黏度、破胶性能以及对煤样甲烷吸附解吸能力影响等方面与常规压裂液进行对比分析。研究结果表明:在同等表面活性剂质量分数下,加入疏水改性羟丙基瓜尔胶的复合压裂液黏度是单组份表面活性剂压裂液的3倍,其破胶时间与表面活性剂压裂液几乎无差别,且仅为HPG压裂液的1/2;复合压裂液对煤样甲烷吸附解吸能力影响明显低于HPG压裂液,其吸附损伤因子虽高于表面活性剂压裂液,但比HPG压裂液低24%。研究结果可为矿用复合压裂液研制提供参考。
Abstract:
In order to make up for the shortcomings of conventional fracturing fluids,such as difficulty in gel breaking,high residue or low viscosity,and large dosage,a hydrophobic polymer/surfactant composite fracturing fluid was formulated by combining and cross-linking the gemini surfactant with hydrophobically modified hydroxypropyl guar gum,and it was compared with conventional fracturing fluids in terms of viscosity,gel breaking performance and influence on methane adsorption and desorption capacity of coal samples.The results show that under the same mass fraction of surfactant,the viscosity of the composite fracturing fluid adding the hydrophobically modified hydroxypropyl guar gum is three times as that of the single-component surfactant fracturing fluid,and its gel breaking time is almost indistinguishable from that of the surfactant fracturing fluid and only 1/2 of that of the HPG fracturing fluid.The influence of composite fracturing fluid on the methane adsorption and desorption capacity of coal samples is significantly smaller than that of HPG fracturing fluid,and its adsorption damage factor,although higher than that of surfactant fracturing fluid,is 24% lower than that of HPG fracturing fluid.The research results can provide reference for the development of composite fracturing fluids for mining.
