This paper presents a lot of static test in laboratory. We have researched the composite gel systems of the inorganic chromium cross-linking agent with HPAM and solid particles. The influence of various factors on the gel was investigated. The core plugging experiment showed that the plugging rate of cores is more than 98% and the breakthrough pressure measured for these cores is more than 30 MPa/m.
