摘要
针对全球深水油气勘探中的深水弯曲水道形态刻画与描述问题,以巴西坎波斯盆地X油田Marlim组为研究对象,基于三维地震资料,运用地震沉积学分析方法,利用地震反射特征分析、谱分解、相干切片等技术手段进行研究。结果表明:Marlim组深水弯曲水道在不同发育时期形态特征不同,早期表现为低弯度窄水道,中期表现为高弯曲横向迁移复杂水道,晚期表现为低弯度宽水道。通过对深水弯曲水道形态特征的刻画和空间演化分析,为该类型储层精细描述提供了一套有效的表征技术,提高了该类型储层的油气勘探精度。
Based on the 3D seismic data,seismic sedimentology analysis,seismic reflection analysis,spectral decomposition,coherence slice and other technical means were used to conduct the morphological characterization of curved channels in global deep-water hydrocarbon exploration by taking the Marlim Formation in the X Oilfield of the Campos Basin in Brazil. Research indicates that the deep-water fan curved channels show various morphological patterns at different development stages,which is a low-curvature narrow channel in the early stage,a high-curvature complex water channel with lateral migration in the middle stage and a low-curvature side channel in the late stage. The morphological characterization and spatiotemporal evolution of deep-water curved channel could provide a set of effective characterization techniques for the fine characterization and the hydrocarbon exploration accuracy for this reservoir category.
