碳酸盐岩储层裂缝评价方法探讨

对于碳酸盐岩储层，裂缝是非常常见的一种储集空间类型，因此，裂缝以及裂缝类型的识别显得尤其重要。通常认为，识别裂缝最有效的方法是利用成像测井进行直观解释，不足之处就是测井成本较高，尤其对于已开发油气田来说。因此如何利用低测井成本方法识别裂缝，是能否提高碳酸盐岩油田开发能力的重要途径。以中东某油气田大量的常规以及成像资料为基础，以成像测井刻度常规测井，运用交会图技术建立了以常规测井为基础的裂缝以及裂缝类型识别方法，并在TAB油田取得很好的应用效果。

Discussion on Fracture Evaluation for Carbonate Reservoir

Fracture is one of reservoir types that often occur in carbonate,it is important to identify fracture and fracture type.In general,the best method to identify fracture is to use image logging to interpret it directly.The image logging can identify fractures and fracture types,but the high logging cost is its disadvantage especially for exploited oilfield.So the primary way to improve exploited potential is how to use low logging cost method to identify fractures in carbonate reservoir.In this paper,we use image logging to calibrate conventional logging,then use cross plot to establish the conventional interpretation module that identifies fractures and fracture types.
