摘要/Abstract

摘要：

油井压裂后，流体在地层中的流动不再是简单的线性流或径向流，流场变得复杂，无法直接运用解析方法求解。为了求解压裂直井的产量公式，将地层中的复杂流场进行了分解，划分成外区径向流、中间线性流和裂缝线性流3个简单流形；对简单流形分别进行求解，并采用水电相似原理和等值渗流阻力法，解析求解得到压裂直井的产量公式。该公式不仅可以计算和预测油井产量，还可以确定压裂裂缝的长度及压裂效果。

关键词: 压裂, 油井, 产量, 表皮因子, 线性流, 径向流, 水电相似原理, 等值渗流阻力法

Abstract:

Fluid flow in the reservoir is no longer merely linear or radial after fracturing, instead, the flow field becomes complex and cannot be directly solved using analytical methods. In order to derive a production formula for fractured vertical wells, the complex flow field in the reservoir was decomposed into three simple flow patterns: outer radial flow, middle linear flow, and fracture linear flow. Each of these flow patterns was separately solved, and by applying the principles of fluid-electric similarity and equivalent flow resistance method, a production formula for fractured vertical wells was analytically derived. This formula can be used to calculate and predict the production of fractured vertical wells, and also to determine the fracture length and fracturing effect.

Key words: fracturing, oil well, production, skin factor, linear flow, radial flow, fluid-electric similarity principle, equivalent flow resistance method
