摘要:
研究了季铵盐型黏弹性表面活性剂用作煤层压裂液的增稠性能、携砂性能、滤失性能、流变稳定性能,并首次根据煤样的声波时差结果分析了煤样饱和各种流体前后的力学参数。试验结果表明,黏弹性表面活性剂VES-2-16和VES-4-16系列具有很好的增黏性能,在170 s-1下可达到30 mPa?s以上,并在高剪切速率下能够长时间保持较强的结构;陶粒在该类体系中的沉降速度为清水中的0.027%~0.3%;该类表面活性剂体系无残渣,初滤失量较大,滤失系数较小。煤样饱和液体后比没有饱和液体的煤样抗压抗剪切强度高,饱和该类压裂液后煤样的抗压抗剪切强度要比饱和水的煤样好。
Abstract:
This paper probes into the viscosity property, sands-carrying capacity, filtration property and steady rheological property of viscoelastic surfactant as fracturing fluid for CBM wells, and for the first time analyzes the mechanical parameters of coal samples before and after saturated by various fluid according to the acoustic time results. The results show that viscoelastic surfactants, VES-2-16 and VES-4-16, have good viscosity property and reach more than 30mPa·s at 170s-1, they also have stable structural viscosity at high shear rate, ceramic settling velocity in the type of viscoelastic surfactants ranges from 0.027% to 0.3% in clear water. The type of viscoelastic surfactants has no residue, large beginning filtration and small filtration coefficient. The coal samples of saturated liquid are more compressive and shearing resistance and the coal samples of saturated fracturing fluid also better than another of saturated water.
