交叉偶极声波测井资料在碳酸盐岩储层评价中的应用
The application of XMAC-Ⅱ log data in evaluation for carbonate rock reservoir
-
摘要: XMAC-II有效地综合了单极子和偶极子技术,提供了地层纵波、横波和斯通利波的丰富信息。总结了阵列声波资料在碳酸盐岩储层评价中的作用,尤其在洞穴型储层有效性判别、裂缝的识别、渗透性分析、流体识别以及各向异性分析等方面具有良好的应用效果。Abstract: XMAC-Ⅱ combines the monopole with the dipole ef-fectively.It can provide much information of compression wave,shear wave and Stonley wave.It is included that the XMAC-Ⅱ data has many functions in reservoir evaluation of carbonate rock,especially in estimating the validity of the cave reservoir,discriminate of fracture,analysis of permea-bility,identification of reservoir fluid and anisotropy analy-sis.The effect is remarkable.
