摘要: 针对采油速度的影响因素,收集了130 个国内外中高渗碎屑岩油田及碳酸盐岩油田的生产动态数据,其中大部分采用注水开发方式开采。按照原油黏度和储集层渗透率将油田分为低黏高渗、低黏中渗、中黏中渗、中黏中高渗、中黏特高渗、中高黏特高渗油田。针对不同类型的油田,开展了不同开发阶段在不同原油黏度、储集层渗透率、油藏储量丰度、井网密度、注采井数比下的采油速度影响因素的分析。分析结果表明,原油黏度、油藏储量丰度、储集层渗透率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,对开发初期影响不大。

Abstract: In view of influencing factors of oil production rate, the production performance data collected from130mid?high permeability clastic rock oilfields at home and abroad are analyzed, among which the most oilfields are developed by water injection process. In terms of crude oil viscosity and reservoir permeability, the oilfields were divided into six types such as low viscosity and high permeability, low viscosity and medium permeability, medium viscosity and medium permeability, medium viscosity and high permeability, medium viscosity and extra?high permeability, and mid?high viscosity and extra?high permeability oilfields. For these different oilfields, the influencing factors of crude oil viscosity, reservoir permeability, reserves abundance, well spacing density, injector?producer ratio on the oil production rate were analyzed. The results indicate that the oil production rate at early stage of water injection development is mainly influenced by the oil viscosity, reserves abundance and reservoir permeability rather than that at late stage of it; the oil production rate at mid?late stage is mainly influenced by well spacing density and injector?producer ratio, the factors have little influence on that at early stage
