摘　　要：以大庆外围超薄油层典型的水平井开发井网为例,选取实际油藏地质和工程参数,运用数值模拟方法,研究油层厚度、渗透率、井距、排距、水平段长及含油砂岩钻遇率等影响因素对水平井初期产能等生产指标的作用规律,并进行油藏实例分析评价。研究成果可为此类油藏的水平井钻井和开发设计提供理论指导和建议。Taking example for development well pattern of typical horizontal well of uhrathin reservoir in Daqing peripheral field, and selecting actual reservoir geology and engineering parameters, using a numerical simulation method studies the law of the effect of reservoir thickness, permeability, well spacing, well array spacing, the length of horizontal section and probability of oil sandstone drilled on horizontal well production index, such as initial productivity. The reservoir case is analyzed and evaluated. The findings can provide theoretical guidance and proposal for horizontal well drilling and development design of this kind of reservoir.
