摘　　要：利用数值试井技术,根据试井解释曲线表现出的外部边界响应特征,建立任意角度、形状及不同类型的多种外边界的组合,并通过不断调整、完善数值模型的结构、形状和相关参数,建立油藏动态数值试井模型,同时采纳试井技术中井点、储层渗流属性、外边界压力响应特征诊断和分析技术,并通过油水井压力历史拟合方式,成功实现了对不规则形状外边界及其变化情况、储层非均质性、优势渗流通道、低序级断层等复杂边界油藏属性的精确刻画。矿场应用实践表明,数值试井在复杂边界油藏的动静态边界描述方面具有明显的优势,为复杂边界油藏动态描述和评价提供了有效的技术支持,较适合于复杂边界及平面非均质性强的水驱油藏试井资料分析。According to well testing interpretation curve characteristics,by creating any angle,shape and the different types outer boundary,and through continuous adjusting and improving the numerical model structure,shape and related parameters,numerical well test technology creates dynamic reservoir numerical model.Numerical well test interpretation method successfully achieved on precise description the irregularly shaped outer boundary and the changes,reservoir heterogeneity,dominant flow channel,low-level faults and other complex boundary reservoir properties,by adopting well point and reservoir flow properties,the outer boundary pressure response characteristic diagnostic and analytical techniques,and through oil wells pressure history matching.Field application practices show that the numerical well testing in complex static and dynamic boundary description has obvious advantages,it provide effective technical support for complex boundary reservoir dynamic description and evaluation,and it is more suitable for complex boundary and strong plane anisotropy water drive reservoir well testing data analysis.
