MFR high temperature profile control agent consisted of 6.5% wood Fortunately sulfonic acid calcium (Ca-LS) and 6.5% crosslinker modified furfural resin (MFR),and the gel solution formed a stable performance gel in the 150~300°C.The higher the temperature, the shorter the gelation time; and the longer the heating time, the higher the gel strength. The gel is very stable at 300°C, and is well in acid and salt resistance. The core experiments showed that the blocking agent's blockage ratio is more than 99% ; the units of the breakthrough pressure was greater than 100 kPa / cm,which the gel solution is a good performance of high-temperature profile control agent.
