| 摘 要： | 变质岩潜山是辽东湾JZ区块重要的油气勘探开发层位.通过对JZ区块潜山裂缝储层的研究,提出一种通过裂缝地层在大、小偏移距地震资料中的衰减梯度差异(DALLO分析)检测裂缝储层的方法.DALLO分析方法实现了在窄方位角采集条件下三维区块的裂缝储层发育程度的预测.根据预测结果,JZ区块潜山裂缝储层分布在距离潜山顶面一定距离的"带"内,且具有显著的非均质特征.

| Abstract: | Metamorphics buried hill is the important prospective and developable layer in JZ oilfield.Through researching the fractured reservoirs in JZ oilfield,the authors present a method to use the difference of attenuation between little and large offsets(DALLO) to detect the fracture.The method can forecast the fractured reservoirs in the area with narrow azimuth seismic data.According to the forecasted results,the fractured reservoirs are distributed over the special zone being apart from the top of the buried ... |
