凝胶颗粒通过孔喉能力的物理实验研究

The study of physics experiments of the ability gelatinous particle through pore throat

通过岩心流动实验能够有效地研究凝胶体系在一定压差条件下的封堵情况,从而为现场调剖堵水提高科学可靠的实验依据。文章首先论述了转变压力的测试装置与测试原理,然后介绍了凝胶颗粒通过孔喉能力的实验准备及实验步骤,进而从不同粒径、不同矿化度、不同膨胀时间这三个方面分析了转向压力的确定。实验结果表明:凝胶颗粒在孔吼中具有较好的流动能力。

Core flow tests to study gel system closure under certain pressure conditions,thereby profile control for on-site water shutoff to improve scientific and reliable experimental evidence. This paper firstly discusses the test device and the test principle of transformation pressure,secondly,the experiment preparation and experiment step of gel particles that through pore throat ability are introduced,and then analyze the determination of steering pressure from three aspects of different size,different salinity and different expansion time. The experimental results show that the gel particles in pore throat has a good flow ability.
