The natural gas reservoir beds of different areas in China can be divided into three kinds, clastic natural gas reservoir bed, carbonate natural gas reservoir bed and special natural gas reservoir bed. They have different combination patterns controlled by deposition, diagenesis and tectonism. Our analysis indicates that the natural gas reservoirs are mainly distributed in the Precambrian, Palaeozoic, Mesozoic, and Tertiary-Quaternary. Craton basin, foreland basin and intracontinental rift basin which contain most of natural gas in China have special geological features and favorable accumulation conditions, and will be important exploration areas in the future.

曲流河点坝、废弃河道级次构型表征对丰富曲流河储层构型模式、指导油气田高效开发具有重要意义。为此,以渤海湾盆地孤岛油田中12—斜检3011井区馆陶组为例,基于分频智能反演技术识别曲流河点坝与废弃河道。首先,通过地震资料分频处理,依据振幅与砂体厚度之间的关系优选最佳频段地震资料,采用支持向量回归(SVR)的机器学习算法进行分频反演;其次,在利用反演数据体平面属性刻画复合河道砂体分布规律的基础上,根据河道边界的地震、测井等响应特征预测单一曲流带;最后,以废弃河道泥质半充填的样式为指导,选取目的层上、中、下部的反演属性切片进行RGB融合,建立废弃河道识别模板,并在定量模式约束下识别点坝和废弃河道。研究结果表明:(1)基于机器学习的分频反演技术能够充分利用不同频段地震信息与测井信息,提高了反演结果的分辨率,可指导河道边界识别;(2)采用RGB融合技术融合河道不同位置的反演属性切片,能够辅助判别砂体之间的空间组合关系,有助于井间废弃河道识别;(3)在地震资料主频为38 Hz的情况下,利用基于分频智能反演的曲流河点坝与废弃河道识别技术在研究区目的层复合曲流带中共识别了4个单一曲流带、13个废弃河道和15个点坝。开发动态资料验证了识别结果的准确性,该方法具有很好的应用前景。

The studies on fluvial reservoir architecture are mainly aimed at outcrop and modern deposition,but rarely at the subsurface reservoir,so there are few effective methods to predict the distribution of subsurface reservoir architectures. In this paper,taking the meandering river reservoir of Guantao formation Gudao Oilfield,Jiyang depression,Baohai Gulf Basin,East China as an example,the archi-tectural modeling method of complex meandering belt reservoir is proposed,that is hierarchy con-straint,pattern fitting and multi-dimensional interaction. Architectures of meandering river reservoir can be divided into three hierarchies: meandering channel sandbody,point bar and lateral accretion body. Different hierarchies of the quantitative architecture pattern are fitted to subsurface well data (including dynamic monitoring data) in different hierarchies through one-dimensional hole,2D profiles and plane and 3D space,which are verified by each other. And then 3D model in different hierarchies is established. At the same time,the quantificational relationship between width of active river and the scale of point bar is set up,and the scale of lateral accretion sand body and shale beddings is con-firmed with horizontal well data. The study not only has significant meaning on the development of geology,but also can improve the oilfield exploitation greatly.

地震属性蕴含大量储层信息,融合多种地震属性可提高储层预测精度。由于地下地质结构复杂、非均质性强,依据单一的地震属性融合方法难以精细刻画储层特征。为此,提出了一种基于Stacking集成学习的分频地震属性融合储层预测方法。该方法主要包括3个部分:①根据不同厚度储层的振幅与频率关系,利用多个频率的地震信息,降低地震属性的多解性;②联合相关性分析和无监督聚类技术优选地震属性,剔除冗余属性特征;③利用能够综合多个差异化模型优势的Stacking集成学习模型,融合不同频段的地震属性,提高地震属性的解释精度。将该方法用于渤海湾盆地埕岛油田,并使用线性公式定量分析法进一步评估Stacking模型的泛化效果。结果显示:与单类预测模型相比,Stacking模型的综合预测性能和可靠性均有显著提升;对应的地震属性融合结果高值区形态更加清晰,融合属性与砂体厚度的相关系数可达到0.92,这表明该方法具有良好的应用前景。
