摘要
通过分析产液剖面和吸水剖面可以了解油藏的纵向动用程度,进而为改善油藏开发效果提供依据。阐述了常规产液剖面与吸水剖面的研究方法,详细论述运用洛伦兹曲线分析油藏产液剖面与吸水剖面不均匀程度的过程,提出定量刻画油藏产液剖面与吸水剖面不均匀程度的"不均匀系数"概念,并结合辽河油田和克拉玛依油田实例进行分析。该研究对于油藏产液剖面与吸水剖面的研究具有一定的借鉴意义。
Analysis of production profile and injection profile can reflect vertical producing degree of reservoirs and provide references for improving development response. This paper introduces traditional research methods of production profile and injection profile, discusses in detail the process of analyzing the uneven degree of production profile and injection profile by using Lorenz curve. The concept of 'nonuniformity coefficient' is put forward to quantitatively present the uneven degree of production profile and injection profile. This paper gives examples of actual oilfields such as Liaohe and Karamay Oilfield, and enriches the study of production and injection profiles.
