摘要:
A氣田B段儲層以石英砂巖和巖屑石英砂巖為主,含少量的巖屑砂巖。不同砂巖類型的氣層電阻率下限值不同,以電阻率為主的氣水識別圖版法適應性差,易導致部分石英砂巖儲層解釋偏高和巖屑石英砂巖儲層解釋偏低。基于實驗室的巖礦分析資料以及測井響應特征,優選反映儲層巖性的敏感性測井曲線,采用模糊綜合評價方法建立補償密度、光電吸收截面指數和深側向電阻率等3條測井曲線與石英相對百分含量之間的非線性映射關系,實現了巖性識別的快速定量評價。在巖性識別基礎上,分巖性建立電阻率和聲波時差的氣水識別圖版,給出不同巖性的氣層下限。應用不同巖性的交會圖版對42口新井進行流體識別,經13個層位試氣驗證,解釋符合率達到了84.62%,應用效果較好,有一定的推廣應用價值。
Abstract:
The reservoir in the B interval of A gas field is mainly composed of quartz sandstone and lithic quartz sandstone, and a small amount of lithic sandstone. Since different types of sandstone have different lower gas layer resistivity, the crossplot chart based on resistivity is invalid, it makes higher resistivity of quartz sandstone and lower resistivity of lithic quartz sandstone. In this paper, based on the laboratory data of rock minerals and the characteristics of logging response, the sensitivity logging curve that reflects reservoir lithology is optimized, and the nonlinear mapping relationship between three curves, i. e. DEN(compensative density), Pe(optoelectronic absorption cross section)and Rt(deep lateral resistivity), and relative quartz content is established by fuzzy comprehensive evaluation, to realize rapid quantitative evaluation of reservoir lithology. Then gas and water identification charts are built based on resistivity and AC data, and the lower limits of different gas reservoirs are proposed. Applied in 42 new wells, the chart provided the result of fluid identification coinciding with the tested result of 13 layers by 84.62%. The good application indicates the method is worthy popularization.
