油井探测半径的计算公式研究

Study on Calculated Equation of Investigation Radius of Production Well

压降漏斗的外部边缘即某一时刻压力波所能波及到的径向距离就是所谓的“探测半径”。油井实际的探测半径是无法计算的 ,所有计算探测半径的公式都是一种近似处理 ,从实用的角度出发得到了一个计算油井探测半径的新公式 ,该公式与计算测试井到断层距离的计算公式是统一的 ,概念上也更加便于理解 。

Investigation radius is so-called the radial range that pressure wave can sweep sometimes at the out edge of the pressure drop funnel. Actual investigation radius of the production well can not be calculated, and all the equations of investigation radius are approximately treated. A new equation of calculating investigation radius of the production well can be founded from usable angle. This equation is consistent to the equation that calculates the range between the test well and the fault, and also conceptually easier to understand and a valuable approximate one.
