In view of the problem of huge computations and multiple solutions, a method for optimizing and accelerating the progress of history matching by using material balance analysis was established. Based on simple measuring data, such as average pressure, daily production rate and PVT test, a material balance model can be constructed for a three phase system of hydrocarbon reservoir. According to the material balance calculation, original oil in place and aquifer parameters can be obtained as optimized parameters for numerical simulation, which contributes to solve the multi-solutions problem of history matching. Besides, by conducting uncertainty analysis using Monte-Carlo simulation method, one can determine the adjustment range of input parameters, which helps the engineer definite a clear direction, reduce the number of computations and consequently accelerate the progress of history matching. The reliability of the proposed method was verified according to two examples.
