水平井水平段长度优化设计与实践

Study on optimization design and practice of horizontal section length

  • 摘要: 根据对南美D油田的油藏特征及水平井开发效果分析,该油田适用水平井的开发模式;利用水平井产能模型,对不同渗透率下采油指数的敏感性、原油粘度敏感性和生产效率敏感性进行分析,计算出适合此类油藏的水平段长度;指出在确定最佳水平段长度时,应综合考虑水平井的经济成本、钻井工艺和地质风险等因素。

     

    Abstract: According to the reservoir characteristics and the analysis of horizontal well development effect of D oilfield,the field is suitable for horizontal well development mode.Using Joshi horizontal well productivity model,through the sensitivity analysis of the productivity index under different permeability and crude oil viscosity sensitivity analysis and sensitivity analysis,the horizontal section length suitable for low viscosity high permeability reservoir is calculated.Whendetermining the optimal horizontal section length,economic costs,drilling technology and geological risk factors should be comprehensively considered.
