摘要
沉积成因过程分析方法是少井区沉积体系研究的有效方法之一。综合利用钻井、测井、岩矿以及三维地震等静态资料,在不同时期湖平面变化框架下,通过古物源以及古沟谷体系研究,明确研究区物源面貌、母岩类型以及供源能力,认识物源区与沉积区之间主要发育的多种沟谷类型高效输砂通道,最终通过对有效物源区、母岩类型以及高效输砂通道三者之间的耦合关系研究,达到预测优质砂体展布的目的。沉积成因过程分析方法在渤中A区沙二段沉积体系研究中的成功应用,很好地指导了该区的中深层储层预测,为该区中深层油气勘探提供了有力支持。
Process analysis of sedimentary origen is one of the effective methods to research sedimenta ry systems in a region with sparse wells. Several static data, such as drilling, logging, lithology, mineral and 3-D seismic, were comprehensively used to research ancient provenance and channel valley system in a framework of lake-level change during different periods, so that the provenance feature, the parent rock type and the ability ofdebris supply were identified in the study region, and the main sand-transportation passages with multiple channel-valley types were recognized be tween the provenance and the sedimentary area. Finally, the distribution of high-quality sandbodies was predicted through analysing the coupling a mong effective provenance, parent rock type and efficient sand-transportation passage. A successful application of this process analysis of sedimentary origen in Member E2s2, BZ-A block, has effective ly guided the middle-deep reservoir prediction and provided strong supports for the middle-deep hy drocarbon exploration in this region.
