摘要:
鄂爾多斯盆地靖西地區下古生界碳酸鹽巖儲層晶間孔、溶孔及裂縫發育,儲層非均質性較強,儲層滲透率難以準確計算,常規測井曲線建立的滲透率模型精度難以滿足工業生產要求;跐B透性地層斯通利波的能量衰減機理,開展斯通利波能量表征方法的研究,優選與滲透率相關性最強的能量參數幅度衰減系數。通過時窗確定、幅度計算、線性擬合等方法求得該參數,建立實驗分析滲透率的定量計算模型,形成了精度較高的滲透率計算方法,適用于裂縫、溶孔、孔隙型的碳酸鹽巖儲層評價。
Abstract:
The Lower Paleozoic carbonate reservoirs in Jingxi of the Ordos Basin are characterized by well-developed inter-crystalline pores, vugs and fractures, and strong reservoir heterogeneity, making it difficult to accurately calculate the reservoir permeability. Moreover, the permeability model built using conventional logging curves cannot meet the required accuracy in industrial production. Based on the energy attenuation mechanism of the Stoneley wave in permeable formation, the energy characterization method of Stoneley wave is studied, and the energy parameter in the best correlation with permeability, namely, amplitude attenuation coefficient, is selected. The parameter is obtained by time window determination—amplitude calculation—linear fitting method, and then the quantitative calculation model of this parameter with the experimental permeability is built. Finally, a high-precision permeability calculation method is established, which is suitable for the evaluation of fractured, vuggy and porous carbonate reservoirs.
