Experimental Study on the Feasibility of PLC Cross-linked Polymer Gel Applied in Loess Layer Plugging
-
Abstract
According to the characteristics of low bottom hole temperature, serious leakage and poor sealing effect by con-ventional plugging materials and methods for loess layer leakage in Yanchang oilfield, PLC cross-linked polymer gel was de-veloped, which could realize rapid cross-linking in low temperature.Taking polymer gel solution with a concentration of 6.5% and organic compound cross-linking stabilizing agent with a concentration of 2%, according to the cross-linking ratio of 10∶1.3, the rapid gelling test was made under the temperature of 17.6℃~40℃.The test results show that PLC cross-linked polymer gel has the characteristics of rapid gelling, strong anti-pollution ability and good compatibility with bridging material, the match usage of polymer gel solution and organic compound cross-linking stabilizing agent has good application prospects for plugging leakage in loess layer.-
