【摘要】 运用声波全波列分析技术中斯通利波反射和差异能量分析,在辽河油田进行了裂缝识别并评价其有效性。由4个波列旋转得到的交叉能量成份可以用来描述碳酸岩中的有效裂缝系统;通过分析计算的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井的一致性,从而对有效裂缝进行描述;用多极子阵列声波测井(MAC)可以提高地震资料解释精度,确定岩性与岩石特性,并探测气层与裂缝。编制出适合辽河油田的岩石力学性质参数图并在生产中得到了应用。更多还原

【Abstract】 Sonic full waveform analysis techniques suc h as Stonely reflections and differential energy analysis have been used to identi fy fractures and evaluate their effectiveness. The cross component energies from the four waveforms are also used to describe the effective fractures networks i n the carbonates. Both the calculated minimum and maximum energies of the anisot ropy and actual production have confirmed the MAC(multipolar array acoustic lo g) data can be used to describe effective fractures in hard formation. The multi polar array acoustic tool can enhance the precision of seismic data interpreta tion. It’s also helpful in lithology identification and gasbearing bed and fra cture detection. Illustrated is the figure of rock mechanics parameters in Liaoh e oilfield and it’s application in practice.更多还原
