摘要： 基于等产量一源一汇稳定渗流速度理论与最大压力梯度场分析结果, 获得了启动压力梯度与注采压差和注采井距的关系式, 并根据渗流启动压力梯度与储集层渗透率关系, 可确定出不同注采条件下油藏能够有效注水开发的渗透率下限。实例分析结果与油田开发实践基本一致, 说明建立的理论方法具有较好的实用性, 可为低渗透油田的有效开发提供科学依据。

Abstract: Based on stable flow velocity model with equal production one source and one gathering and analysis of maximum pressure gradient field, relationship between starting pressure gradient and injection-production differential pressure and producer-injector spacing is presented. And using starting pressure gradient vs reservoir permeability, the cutoff permeability suitable for effective waterflooding of reservoir under different injection-production conditions is given. The theoretical and practical results are generally identical, indicating its good practicability, which can be as a guide for effective development of low permeability oilfield.

Key words: low permeability reservoir, pressure gradient, spacing, cutoff permeability
