摘要： 目前常用的油井探测半径计算公式都是针对直井提出的,也只适用于平面径向流,对于平面单向流的情形并不适用。采用渗流力学方法,通过定井底流压的生产方式,定义了平面单向流探测距离的概念,然后,通过压力脉冲波的传播理论,推导出了平面单向流的探测距离计算公式。该式在水平井生产、排状井网生产或河道条带地层存在平面单向流的情况下,可用来研究压力的波及范围和探测距离问题,以便更好地指导油井生产。

Abstract: The conventional formula for calculation of investigation radius of wells is deduced for vertical wells, which can only be applicable for radial flows rather than for parallel flows. By means of the flow theory in porous media and the production scheme of constant bottom-hole pressure of a production well, the concept of investigation distance of parallel flows is defined. Then the formula of investigation distance of parallel flow is deduced with the propagation theory of pressure pulse wave in formation. This formula can be used for situations of horizontal wells, parallel well patterns and channel strip sands, solving the problems of the pressure propagation scope and the distance of investigation in order to guide the production better.

Key words: production well, investigation distance, parallel flow, radial flow, formula, formation
