| 摘 要： | 松南气田营城组为一套火山岩储层，岩石类型多而复杂，裂缝与孔洞分布不均，储层的各向异性强，常规测井方法难以准确评价这类储层。利用声电成像测井图像，可以有效识别火山岩的岩石结构与岩相，提取裂缝并计算裂缝参数，通过裂缝产状与最大水平主应力的关系评价裂缝的有效性。成像测井为火山岩地层的测井解释提供了更丰富的评价信息，提高了火山岩储层的解释水平。

| Abstract: | The Yingcheng formation in Songnan gasfield is volcanic rock reservoir with complicated lithology,unevenly developed fracture and pore,and very strong anisotropy.As a result,it is difficult to evaluate the reservoir correctly with conventional logging methods.However,acoustoelectric imaging logging can be of great help to effectively identify the structure and lithofacies of volca nic rocks,to obtain fracture for the calculation of fracture parameters,and to evaluate fracture effectiveness based on the rela... |
