摘要： 为确定不同开发阶段影响采油速度的主要因素,利用我国26 个油藏的生产动态数据,采用偏相关性分析方法分析了渗透率、粘度、储量丰度、井网密度、注采井数比对采油速度的影响。分析结果表明:渗透率、粘度、储量丰度主要影响开发初期的采油速度,对开发后期影响较小;井网密度和注采井数比主要影响开发中后期的采油速度,初期影响小。

关键词: 采油速度, 偏相关分析, 影响因素

Abstract: In order to clarify the major affecting factors of oil recovery rate in different exploitation phases, this article analyzes uses the partial correlation analysis method to analyze the influences of permeability, viscosity, reserves abundance, well spacing density and injector-producer ratio on the oil recovery rate by using performance data from domestic 26 reservoirs. The result indicates that the permeability, viscosity and reserves abundance mainly affect the early oil recovery rate, seldom influence the late one; the well spacing density and injector-producer ratio mainly affect the late oil recovery rate compared with the early one.

Key words: oil recovery rate, partial correlation analysis, influencing factor
