Development and application of high temperature gel in Liaohe oilfield

Using resorcin and formaldehyde as cross linking agent,adding heat stabilizers,compounded with part polyacrylamide solution,which formed high temperature gel adjustable profile control agent.Research has identified adjustable profile control agent,inspected polyacrylamideof crosslinking agent volume influence to gel strength and gel time,the adding of heat stabilizers to gel system enhanced gel resistant temperature,and the core sealing test has been carried.High temperature gel adjustable profile control agent has been applied in liaohe oilfield 98 steam stimulation Wells and achieved good effect for oil increasing.
