Abstract: Gas injection technology is used to improve oil recovery in Tuha oilfield, sensitivity evaluation has been conducted by means of numerical simulation orthogonal experiment method. The studies show that the prominence order of the factors is water saturation, injected gas composition, pressure maintenance, and input speed etc. The study provides the foundation for dynamic monitoring and scheme adjustment. It also has reference significance to IOR by gas injection.

Key words: gas injection, IOR, orthogonal experiment method, hydrocarbon injection, influence factor
