To solve water control problem in low permeability and low temperature reservoirs with water flow predominant channels, a multi-component crosslinked polymer (MCCP) gel was studied in the lab. The matching relationship between the gel’s performance and predominant channels in heterogeneous formations was studied from the aspects of static performance, rheology, diversion adjustment ability, plugging property and migration depth. The experimental results showed that, at the temperature of 40℃, the initial gelation time was of about 3 h, the completely gelling time was of 24 h, and the gel strength was more than 50000 mPa?s. The shear thinned phenomenon occurred before gelation. The selective plugging property of the MCCP gel was good in heterogeneous formation whose permeability differential was less than 10. After injecting 0.3 PV MCCP solution, for the predominant channels with permeability of 600×10^-3、1000×10^-3、10000×10^-3μm², the gel had good plugging property. Its final migration depth in sand filling tube with permeability of 10000×10^-3μm² could reach 3/5 of the total length; for sand filling tubes with permeability of 1000×10^-3 and 600×10^-3μm², the depths both could reach 2/5 of the total length.
