Songliao basin is located in north west of the Pacific continental margin,its main area lies in the middle of Heilongjiang plates.The compression stress field of the upper crust in Songliao basin is different from place to place especially from north to south of the area.With plate tectonics,the authors studied the regional tectonic characteristics of North Harbin in Songliao basin using the long seismic profiles.With seismic analytic interpretation the authors gained that there are uplifts and depressions...

Songliao basin is located in north west of the Pacific continental margin,its main area lies in the middle of Heilongjiang plates.The compression stress field of the upper crust in Songliao basin is different from place to place especially from north to south of the area.With plate tectonics,the authors studied the regional tectonic characteristics of North Harbin in Songliao basin using the long seismic profiles.With seismic analytic interpretation the authors gained that there are uplifts and depressions in East and West of the area,and most of the depressions are in the middle part of the basin.From South to North the sedimentary thickness gradually becomes thin.The earlier fault movements resulted in the tectonic characteristics of the area with alternating uplifts and depressions.

松辽盆地位于西太平洋大陆边缘北部,其主体部分位于黑龙江板块群的中部。松辽盆地整个上部地壳所受到的挤压应力场在南北两大地区存在空间差别。在板块构造理论指导下,利用研究区内的地震长剖面资料,研究松辽盆地滨北地区区域构造特征。通过分析认为,滨北地区东、西部多为隆起或斜坡区,而中部多是凹陷,从南向北,地层沉积厚度逐渐变薄。早期的断层活动导致了凹陷内凹隆相间的构造特点。

Shortly after the constitution of this project,in order to verify the feasibility of the theoretical research implementation,we proposed an additional requirement of direct involving in the production of oil and gas reservoirs in the outer part and deep part of Daqing,so that the overall merit of both theoretical research and practical application of this project can be improved.With the successful construction of PC-clusters and development of the seismic data parallel processing system plus assistant software packages in 1998,we built up the 3D wave equation pre-stack depth migration algorithm and the corresponding software in 2000,which is synchronous with international seismic exploration community.Such an achievement greatly improves the capability of seismic imaging in China.In the year of 1999,we assembled an eight-node PC-cluster and processed 150 km-long seismic profiles.In paticular,on the depth map of line 82,we clearly imaged the internal structure and fault character of an uplift in a depression area.After a rearrangement of 3D seismic exploration and with many research works,a great break through was achieved accomanying the drilling of the Xushen No.1 well and leading to the discovery of the huge gas field in Daqing.This success remarkably improves the continuable development foreground of Daqing oilfield.We have also built up two reservoir geophysics research centers in Beijing and Daqing,respectively.It has been proved that proper and reasonable research organization and activity will benefit the integration and application of the products of a great scientific project,and is key to make progress with combined efforts consecutively and efficiently.

本项目立项不久,为验证所开展理论研究的有效性,从各课题优选内容,提出直接介入大庆外围及深部油气储量预测工作的额外研究内容,旨在于提升本项目的理论研究水平和应用价值.1998年研制集群计算机、研发叠前地震资料并行处理平台及辅助软件包,促成本项目与国际同步(2000年)生成“三维波动方程叠前深度偏移成像”算法及软件,提升了我国在勘探地球物理研究领域地震成像的能力.1999年,在大庆组装8个节点集群机,处理150km地震资料,在82线的深度剖面上,发现“凹中隆”内部结构和断裂特征.后经布署三维地震勘探及多项研究,大庆决定钻探“徐深1井”并获得重大突破,揭开了大庆发现大气田的序幕,极大地显现并提升了大庆油田的可持续发展空间.分别在北京和大庆两地设立“油储地球物理研究中心”,业已表明,合理的科研组织思路及举措,有利于重大项目成果的集成与应用,以及形成研究团队的群体突破态势.
