摘要
曹妃甸11-6油田是渤海海域以明化镇组河流相储层为主要目的层的油田。河流相储层岩性纵向和横向变化大,储层薄且往往叠合或交叉,连续性差,储层预测和描述是油田储量评价中的难点和关键点。由于受分辨率限制,基于反射层的传统三维地震解释往往不能满足河流相储层描述的需要,因此,各种深入发掘地震资料有用信息的地震储层描述技术飞速发展。本文在分析曹妃甸11-6油田河流相储层地质特征及地球物理特征的基础上,以测井约束反演及地震属性分析技术开展油田储层描述,经开发井证实,该套技术能够高效、准确的预测和描述该油田河流相储层分布,能够满足油田储量评价的需要,对该地区相同层位的河流相储层描述具有一定借鉴作用。
The CFD11-6 oilfield lies in the Bohai offshore area,the main zone of this oilfield is fluvial reservoir of Minghuazhen formation.The thin thickness,great lateral changes and poor continuity are the main features of fluvial reservoir,it is hard to describe the fluvial reservoir.Many seismic reservoir description methods of fluvial reservoir were applied widely now.According to study the geological and geophysical features of CFD11-6 oilfield,the log constrained inversion and seismic attribute techniques wer...
