远近偏移距属性差在碳酸盐岩储层裂缝检测中的应用——以流花11-1油田为例
|
摘要
碳酸盐岩储层裂缝对油气田开发生产影响较大。以流花11-1油田为例,在远近偏移距属性差检测裂缝的方法原理分析及岩石物理正演模拟的基础上,寻找能够识别裂缝的有效属性参数,最终利用远近偏移距属性差预测了该油田碳酸盐岩储层裂缝的分布情况,其结果与实际钻井相吻合,可为油田的后续开发提供有力的技术支持。
Fractures in carbonate reservoirs will have greater impacts on oilfield development.As a study case,the effective attribute parameters to detect fracture distribution in carbonate reservoirs were sought in LH11-1 oilfield,on a basis of analyzing the method and principle to detect fractures by differential attribute between far and near offsets and making the petrophysical forward modeling.Finally,the differential attribute between far and near offsets was used to predict fracture distribution in this oilfield carbonate reservoir,and the prediction accords well with the actual drilling results,providing a strong technical support for further development of the oilfield.
