摘要： 洞穴型储集层是塔中地区鹰山组碳酸盐岩油气藏重要的储集层类型，因其层位、规模、充填物类型、充填程度等复杂多变，使用单一的地球物理或测井模型难以对其定量刻画。利用地震属性确定储集层深度，应用成像测井与常规测井相结合，刻画洞穴垂向规模、充填物性质及充填程度，用试井、试采等生产资料及井间地震属性评价储集体横向层布。研究表明，塔中地区鹰山组洞穴型碳酸盐岩储集层地震反射特征以串珠状为主，占86%，发育在距鹰山组顶界面240 m的范围内，洞穴高度大多为0.5~2.0 m，多被泥质、角砾等充填或半充填，平均充填率达到62.8%；洞穴横向上呈孤立状分布，部分与裂缝构成缝洞型储集空间。

Abstract: Vuggy reservoir is one of important types of carbonate reservoirs, its complex and varied features in horizon, scale, filling matter type and filling degree, etc, make the reservoir difficult to be quantitatively discribed using single geophysical model or well logging model.This paper determines the depth of the vuggy carbonate reservoir of Yingshan formation in Tazhong area with the seismic attributes, discribes the vertical scale of vugs, filling matter property and filling degree by imaging logging?conventional logging combination, and evaluates the lateral distribution of vugs by means of the well testing, production test data and the interwell seismic attributes. The studies show that the vuggy carbonate reservoir in this area is characterized and dominated by moniliform seismic reflection, which accounts for 86%,with distribution range of 240 m away from the top Yingshan formation, and the vugs or caves mostly range from 0.5 m to 2 m in height, semifilled and/or fully filled with clay, breccia, etc, with filling rate of 62.8% in average. In lateral, the distribution of vugs is isolated, partly forming fractured?vuggy reservoir with fractures
