【摘要】 论文以大庆葡萄花油田为例,论述了应用三维连片高分辨率地震地震资料进行构造精细解释和低级序断层研究,结合钻井和开发动态资料,对已开发油田进行油藏构造精细描述的内容、思路、方法和技术。葡萄花油田构造是大庆长垣二级构造带南部最大的一个构造,构造向南部分延伸为敖包塔构造。葡萄花油田于1979年投入开发,自1999年进入综合开发调整阶段。随着油田勘探开发的深入,小断块、小砂体及其隐蔽圈闭所形成的油气藏成为油田滚动扩边的目标,幅度5-10m的低幅度构造、断距3-5m的低级序断层、1-2m薄砂体对油田开发的注采井网和剩余油分布起着控制作用而成为油田剩余油挖潜的目标。利用三维高分辨率地震资料对开发中的油田展开连片构造精细解释和低级序断层研究,对油田的滚动扩边和开发调整部署具有重要指导作用。论文以高分辨率三维地震资料精细解释应用为主,将已开发油田的外围滚动扩边和油田内部的剩余油挖潜结合起来,充分发挥地震资料在油田滚动开发和精细油藏描述中的作用。主要采用地震资料的剖面解释、相干数据体解释、三维可视化体解释等层位和断层的精细解释技术以及连片变速成图技术,完成了葡萄花油田的连片三维地震资料的精细解释和构造成图,落实了大量的断层和低幅度构造、小断块和断鼻构造。在连片三维精细构造解释的基础上,以油田的精细地质及低幅度构造研究成果为依据,采取多种低级序断层地震资料识别与解释技术,落实了低幅度构造研究断块的四、五级断层。论文然后根据连片三维构造精细解释的成果描述了研究区的构造及断裂特征,并对圈闭的要素进行细致的描述,分析了葡萄花油田葡I油层的区域、局部构造特征,结合构造演化特征、构造发育史以及油藏类型和油气成藏特征;研究了低幅度构造研究区的低级序断层分布特点,结合油田开发动态资料分析低级序断层对开发的影响。论文最后根据连片三维构造精细解释和低级序断层的研究成果提出了葡萄花油田的外围构造有利区和低幅度构造研究断块的有利剩余油挖潜目标。更多还原

【Abstract】 This paper taking Putaohua oilfield in Daqing as an example, discusses the application of three-dimensional sectors-connecting high resolution seismic data interpretation and low-level tectonic sequences, in combination with drilling and fault to develop dynamic data are already oilfield development, the structure of the reservoir description, thought, method and content.Putaohua oilfield is Daqing Changyuan second-order tectonic belt south, one of the biggest tectonic structural toward the south tower structure for Aobao outspread part. Putaohua oilfield in 1979, Putaohua oilfield development since 1999, put into comprehensive development adjustment stage. With the further exploration and development of oil fields, minor fault blocks, small sand body and hidden trap forming reservoirs become oilfield of rolling extension, 5-10m target range of low amplitude structure, broken away from 3-5 m low-level sequence faults, 1-2m thin sand body of oilfield development of injection-production patterns and residual oil distribution and become plays control potential residual oil target. Using three-dimensional high resolution seismic data of the oilfield development on structure and low sectors-connecting sequence of oilfield, study the development adjustment rolling extension and deploy play an important guiding role.Taking high resolution of 3-D seismic data interpretation, application of peripheral oilfield has rolling extension and internal residual oil combined, full potential seismic data in oilfield development and fine role in reservoir description. Main USES of seismic data interpretation, coherent body of data section explains, 3d visualization body interpretation and fault of technology and mapping technique, variable shall finish the three-dimensional sectors-connecting Putaohua oilfield of seismic data interpretation and tectonic mapping, carry out a lot of faults and low amplitude structure, small fault block and broken nose. In sectors-connecting of 3-D fine structure interpretation on the basis of geological and low oil fine structure based on research achievements of amplitude, adopt various low-level sequence fault earthquakes material identification and interpretation techniques, implement the structural study of low amplitude of the fault block 4, 5 faults. Paper and then according to the structure of three-dimensional sectors-connecting described the research achievements in construction and fracture characteristics of traps, and meticulous description of the elements are analyzed, Putaohua oilfield of reservoir area, the Portuguese I local structural characteristics, combining the characteristics of structural evolution, the development and the reservoir type and hydrocarbon accumulation characteristics, The research of tectonic zone of low amplitude, low fault distribution characteristics of sequence with dynamic data analysis of oilfield development sequence of development of the lower fault. Based on the three-dimensional sectors-connecting paper structure and low sequence of fault proposed research achievements of Putaohua oilfield construction advantageous area and the periphery of the structural study of low amplitude of fault block potential targets.更多还原
