The invention provides a chrome aluminum ion compound profile control agent for a crack type oil deposit and a use method thereof and relates to the field of practical chemistry of oil fields. The profile control agent provided by the invention is prepared from the following raw materials: three partially hydrolyzed polyacrylamides in different molecular masses of 1200*10<4>, 1900*10<4> and 2500*10<4>, chromic acetate, sodium sulfite, aluminum citrate, oxalate and sodium potassium tartrate. Two profile control agent segments with different characteristics are prepared in the manner of adjusting the components of the raw materials, so that the double-segment synergic profile control effect can be realized. According to the invention, the crack type oil deposit is stably plugged in the manner of injecting the double-segment compound profile control agent into the crack type oil deposit, so that the water driven petroleum recovery efficiency after profile control can be increased. The profile control agent provided by the invention has the advantages of simple preparation method, high shearing resistance, low viscosity before forming glue, easiness in injection, adaptability to the prepared water in mineralization degree of 500mg/L-35000mg/L, and low-cost and easily-obtained raw materials.
