Abstract:

About 60% petroleum reserves are low-permeability reservoirs in China now. Fracturing is needed in order to improve productivity of these reservoirs. The research of optimizing fracturing parameters by the use of numerical simulation can offer theory guidance to actually working design. Firstly, mathematics pattern was founded. Then,  different values of radius,flow conductivity and direction of fractures were calculated,and their effects on productivity and water cut were analyzed. Computation results indicate that this method can improve the effect of fracturing in low-permeability reservoir, and optimal values of fracturing parameters do exist.

Key words: low-permeability, fracturing, parameter optimization, numerical simulation
