多极子声波测井资料在辽河油田硬地层中的应用
|
摘要
通过声波全波列测井中斯通利波的反射和差异能量分析,在辽河油田中进行了裂缝识别并评价了其有效性。利用由4个波列旋转得到的交叉能量成分可以描述碳酸盐岩中的有效裂缝。通过分析计算各向异性的最小和最大能量,并通过不同井的实际产量已证实这些计算结果的一致性,从而对有效裂缝进行了描述。用多极子声波测井可以提高地震资料解释的精度,确定岩性与岩石特征,并探测气层与裂缝。编制出适合辽河油田使用的岩石力学性质参数图并应用在生产中。
Sonic full waveform analysis techniques such as Stoneley reflections and differential energy analysis have been used to identify fracture and evaluate their effectiveness.The cross component energy from the four component waveform rotations is also used to describe the effective fracture networks in the carbonates,which can be achieved by analysing the minimum and maximum energy of the anisotropy computation and verifying consistent characteristics between different wells with actual production from those wells.The multipole array acoustic tool can enhance the precision of seismic interpretation. It's also useful in lithology identification and gas-bearing bed and fractures detection.To draw pictures of litho - mechanics parameters that are suitable for production of Liaohe oil field,this method was put into production.
