摘要： 针对普光气田飞仙关组鲕滩储集层厚度大、埋藏深、非均质性强以及Ⅱ、Ⅲ类储集层与围岩物性差别小的特点,在分析稀疏脉冲反演方法和关键参数的基础上,重点加强合理子波提取、精细储集层标定、精确地质模型建立等方法研究,进一步利用储集层与非储集层岩石物理参数的界限,定量预测储集层的空间展布。该方法在普光气田主体开发井位设计中取得了很好的应用效果,预测符合率达83.9%,同时为普光气田周边区块的定量预测提供了借鉴经验。

Abstract: The oolitic shoal facies reservoir of Feixianguan formation in Puguang gas field is characterized by big thickness, deep burial, strong heterogeneity and small difference in lithology between II- and III-type reservoirs and neighboring rock. This paper analyzes carbonate sparse spike inverse (CSSI) method and the key parameters, and highlights the fair wavelet extraction, fine reservoir calibration and exact geologic modeling, etc. The spatial distribution of reservoir is predicted quantitatively using the limits between petrophysical parameters of the reservoir and non-reservoir. This method has been applied to the main development well locations design of Puguang gas field, with the prediction rate of 83.9%, which can be as a guide for quantitative prediction of surrounding blocks in Puguang gas field.

Key words: Puguang gas field, carbonate rock, oolitic shoal reservoir, CSSI, petrophysical modeling
