地震技术创新在大庆油气勘探中的实效性分析

ANALYSIS ON THE EFFECTIVENESS OF SEISMIC TECHNICAL INNOVATION IN DAQING PETROLEUM EXPLORATION

介绍了松辽盆地中浅层、深层以及海拉尔盆地的地质特点，总结了2000年以来地球物理研究人员针对地质问题开展持续不断的攻关，形成保持振幅、频率特征的高分辨率处理技术，扶杨油层河道砂体地震识别技术和薄互层砂岩油藏地震反演技术，在扶杨油层见到了清晰的河道和点砂坝，实现了扶杨油层勘探的突破；形成了超大数据体三维地震连片叠前时间偏移和深层火山岩及储层地震识别技术，并发现了庆深大气田；发展形成了复杂断块三维地震叠前深度偏移技术，实现了海拉尔盆地复杂构造良好成像，先后成功部署了贝16、贝14等井，实现了苏德尔特构造带勘探的重大突破。

This paper briefly introduces the geological characteristics of mid-shallow layers, deep layers in Daqing Oilfield and that of Hailaer Basin; also it reviews the study course of geophysical researchers aiming at geological problems since 2000. Through hard work, high resolution processing technology of maintaining amplitude and frequency characteristics, seismic identification technology for Fuyang channel sand reservoir and seismic inversion technology for thin interbedded sandstone reservoir have been developed, with which fiver channel and point par in Fuyang oil layers were displayed clearly, implying a breakthrough in the exploration of Fuyang oil layers. 3D prestack time migration technology with ultra-large seismic data volume, as well as deep volcanic rock and seismic identification technology, have been generated , with which Qingshen gas field was discovered. 3D pre-stack depth migration technology for complex fault block is formed to achieve a good imaging of Hailaer complex structure, with which Well Bei 16 and Well Bei 14 have been successfully deployed, being a major breakthrough in the exploration of Suderte tectonic belt.
