Aming at the development status of one high pour - point oil reservoir having high wax content, high wax precipitation point and freezing point, temperature sensitive of oil property, and the changes of seepage law as well as the large damages caused by the injection of room temperature water, etc. , the influence of water injection having different injection temperature, injection rate and well spacing on the temperature field distribution was studied by using the reservoir numerical simulation model to determine the reasonable water injection parameters. The results showed that the optimum water injection temperature is 66℃ ,injection rate is 600m3/d, and the optimum well pattern is five - spot well network.
