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 pres-sure ,secondly ,the experiment preparation and experiment step of gel particles that through pore throat ability are introduced ,and then an-alyze the determination of steering pressure from three aspects of different size ,different salinity and different expansion time .The experi-mental results show that the gel particles in pore throat has a good flow ability .
