| 摘 要： | 准噶尔盆地西北缘风城地区二叠系风城组岩性复杂,岩性主要以泥质白云岩为主,储层表现为裂缝—孔隙双重介质特点,预测裂缝发育走向和密度是油气勘探的关键环节之一。通过对比分析目前各类裂缝预测技术,选择了叠前方位各向异性裂缝检测技术。首先开展方位角各向异性正演模拟,确定该区各向异性的主要因素,其次进行了地震资料分方位角处理,完成叠前地震方位各向异性属性的计算。结合井资料对该区裂缝发育强度和走向进行预测,指明了进一步油气勘探的方向,后续钻探结果表明,裂缝预测结果与钻井结果吻合较好,证明此项技术在该区行之有效。

| Abstract: | Lithology is complicated in Permian Fencheng Formation of Fencheng Field in the northwestern margin of Junggar Basin. It is dominated by mud dolomite and has pore-fracture dual media reservoir. To predict fracture strike and density is one of the key parts of oil and gas exploration. The fractured reservoir prediction technique based on P-wave azimuthal anisotropy using prestack seismic data is selected by comparing all kinds of fracture prediction techniques. First, forward modeling based on azimuthal anis... |
