Based on detailed geological modeling of block M and the result of Numerical Simulation, the paper optimized the best well pattern in twenty-two well patterns between 5-spot well Pattern、Invert 7-spot well Pattern and Invert 9-spot well Pattern. The results show that: based on the principle of optimization well pattern, the WP1、WP7、WP15 are better. Considering the Production rate and time, Invert 9-spot well Pattern has a higher Production rate; but 5-spot well Pattern can enhanced energy supplement to improve the oil recovery. Considering the formation pressure and oil recovery, 5-spot well Pattern is the best well pattern in all. Reasonable Well Pattern can help improve oil recovery and keep formation pressure, which has great influence on development effect. In the process of developing low permeability reservoir, vertical wells combines with Horizontal Wells are widely used. Based on detailed geological modeling of block M and the result of Numerical Simulation, the paper optimized the best well pattern in twenty-two well patterns between 5-spot well Pattern、Invert 7-spot well Pattern and Invert 9-spot well Pattern. And choose the best well pattern, which will have leading guidance on developing M block.
