摘要
针对大民屯凹陷沙三段及潜山等有利目标区的精细采集、处理及解释技术攻关工作,分别采用了最佳岩性激发技术、大型障碍区特观设计技术、提高地震资料信噪比和成像精度处理技术及地震属性三维可视化解释技术的攻关应用,地震资料品质有了显著的提高,信噪比在2.5~3.5 s由以前0.5~0.7提高到1.0~1.5;频带宽度由10~50 Hz提高到8~90 Hz,潜山构造形态更加可靠。新发现和落实有利圈闭45个,面积156 km2,发现了沈262、沈628等百吨级高产油流井,上报探明石油地质储量3 574×104t。为寻找岩性及潜山油气藏积累了宝贵的经验。
For the research on the acquisition,processing and interpretation of prospects in Sha3 Member of Damintun depression and buried hills,the optimum lithology shooting techniques,special design technique for massive barrier area,processing techniques for improving signal-to-noise ratio of seismic data and image accuracy,and 3D visualization interpretation technique have been applied.With the application of the techniques,the quality of seismic data has been increased obviously: The signal-to-noise ratio at 2.5-3.5 s has increased from 0.5-0.7 to 1.0-1.5;The bandwidth has increased from 10-50Hz to 8-90Hz,and the geometry of burial hill structure is more reliable.45 favorable traps are found and established with the area of 156km^2,high oil flow production wells with production over 100 tons,such as Well Shen262 and Well Shen628,have been discovered,and the reported proven oil in place is 3574×10~4t.The research can provide the discovery of lithologic and burial hill reservoirs with valuable experience.
