          摘要:
          海上油田生產管柱結構較為復雜,且RPM-C/O測井受環空流體影響嚴重。剩余油飽和度的解釋精度直接關系到綜合調整的決策部署,通過現有RPM-C/O測井資料分析,環空流體是影響渤海油田RPM-C/O測井解釋的主要影響因素。基于線性內插算法,提出了基于標志層刻度的環空流體“飄移”校正方法,建立了適合渤海油田的“扇形圖”解釋模型。在標志層刻度基礎上,得到了各目標油田的變骨架碳氧比值(C/Oma)井眼綜合校正系數,開發適合渤海油田的RPM-C/O剩余油飽和度解釋軟件。該方法通過復雜管柱井的實例分析,提高了RPM-C/O剩余油飽和度解釋精度,與生產動態資料相吻合,解決了渤海油田復雜管柱環境下RPM-C/O剩余油飽和度解釋誤差大的問題,對開發后期剩余油的挖潛具有重要的指導意義。
          Abstract:
          Abstract: The offshore production string structure is complex, and the RPM-C/O logging is seriously affected by the fluid in wellbore annulus. The interpretation accuracy of residual oil saturation is directly related to the decision-making deployment of comprehensive development adjustment. Through the analysis of existing RPM-C/O logging data, the annulus fluid is the main influencing factor affecting the interpretation of RPM-C/O logging in Bohai Oilfield. Based on the linear interpolation algorithm, the “floating” correction method of the annulus fluid based on the mark layer scale is proposed, and the “sector graph” interpretation model for the Bohai Oilfield is established. Based on the scale of the mark layer, the comprehensive correction coefficient of the changing value of C/O ratio of matrix(C/Oma)of each target oilfield is obtained. The RPM-C/O residual oil saturation interpretation software for Bohai Oilfield is developed. Through case study of complex production string wells, it is proved that the method improves the interpretation accuracy of RPM-C/O residual oil saturation, which is consistent with the production dynamic data. The developed method could address the large error of RPM-C/O residual oil saturation interpretation under the complex production string environment in offshore Bohai Oilfield, presenting important guiding significance for the potential tapping of residual oil in the later development stage.
