摘　　要：合理的井网和井距是油藏开发的关键参数,关系到油藏的开发效果及采收率等重要指标。通过采收率与井网密度的关系式计算了油藏的井网密度,并通过经济极限开发指标计算了合理的井距范围,在此基础上运用CMG油藏数值模拟软件,模拟了该稠油油藏六种井网及四种井距下的开发模式,并预测了含水率及采收率等指标,从中优选出了一套方案,为油藏的科学高效开发提供了理论依据。Reasonable well pattern and well spacing is the key parameter of reservoir devel- opment, related to the important index of reservoir development effect and recovery rate. In this paper, through the relationship between recovery rate and well density, calculating the well spacing density of reservoir, and calculating the the development index of economic limit. On this basi reasonable well spacing range through s, through the CMG numerical simula- tion software, simulation of the heavy oil reservoirs in six well patterns and four well spacing under the development mode, and to predict the water content and the recovery rate index, the optimum process of a set of scheme, provides a theoretical basis for the scientific and ef- ficient development of reservoir.
