对“基于流量的探测半径计算方法研究”一文的商榷

Deliberation on the paper “New computing method for radius of investigation based on flow rate”

为了给油田开发设计提供依据,须准确确定油井的探测半径。根据渗流力学的基础理论研究了油井探测半径的计算问题,分析了各种计算公式存在的问题。认为传统的探测半径计算公式是通过压力波的波峰进行定义的,其理论性很强。笔者提出的公式是通过地层压力变化的近似解的外部边缘进行定义的,并与计算断层到测试井距离的公式统一起来,其实用性较强。

Investigation radius of oil wells must be determined accurately for providing design parameters for oilfield development.Based on the basic theory of fluid seepage mechanics in porous medium,the calculation of the investigation radius of the oil wells is researched,and all the formulae of the investigation radius are analyzed.The conventional formula of the investigation radius is defined by the peak time of pressure wave,which is mainly on theory.The formula proposed by the author of this paper is defined by the out edge of approximate solution of the formation pressure,which is more practical.Moreover,the new formula conforms to the formula calculating distance of fault to testing wells.
