摘　　要：在试井设计与分析中,调查半径是重要的参数之一,不但可以利用调查半径来估计测试到所要求的地层范围需要的时间,而且还可以利用调查半径来计算井点到特征边界的距离。建立条带形非均质碳酸盐岩储层的数学模型,应用边界元方法求解,得到了条带形非均质碳酸盐岩储层中调查半径随时间的变化规律,利用调查半径来估算井点到条带边界的距离,可以为油田制定合理的开发方案提供现实依据。In well test design and analysis,investigating radius was one of the important parameters,it could not only use the investigations of the radius to estimate the required well testing time,but also could use it to calculate the distance between the well point and characteristic border.A strip-shaped heterogeneous carbonate reservoir model was established,the boundary element method was deployed to obtain the relationship between the investigating radius and the response time in strip-shaped heterogeneous carbonate reservoirs.The investigating radius is to estimate the distance from the well point to the border strip,it can provide realistic and reasonable basis for setting up oil field development plans.
