| 摘 要： | 以膨胀性的粘土为主要研究对象,通过粘土浆体的流变性实验和填砂管渗流实验,并使用一种新研制的微流量测量工具,研究了低渗岩心在较低流速下的渗流特性;利用微尺度流动理论,Einstein粘度定律等进行了理论分析,对引起低渗透油藏低速非线性渗流的影响因素进行了初步的探索.结论认为,粘土的膨胀性以及其水化后形成浆体的流变性是引起低速非线性渗流的主要因素之一. |
| 关 键 词： | 低渗透油藏 低速非线性渗流 启动压力 粘土膨胀 微尺度 |

| Abstract: | Firstly,swelling clay was chosen as the main research target in this paper.Through theological experiment on clay slurry and flow experiment in sand packed model,the low-velocity flow characteristics in a low permeability core were studied by using the self-designed micro-flux measuring instrument.Based on the rheoretical analysis of micro-scale flow theory and Einstein's viscosity law,a preliminary study has been carried out on the mechanism of low-flux nonlinear flow in low permeability reservoirs.The final results showed that the expansibility of clay and the rheological property of clay slurry are the two main factors causing the low-flux nonlinear flow. |
| Keywords: | low permeability reservoir low-flux nonlinear flow starting pressure expansibility of clay micro scale |
