摘要

华北油田冀中探区深层构造复杂、表层结构变化快,区内大型障碍物众多,环境干扰严重,在该区进行地震资料采集技术难题多。早期采集时受采集技术及装备的制约,资料品质较差,近几年在高精度三维地震采集时通过针对性设计优化观测参数、野外合理实施、精细表层结构调查、逐点设计激发参数、环境噪声压制、网格化资料品质分析等技术及措施的应用,获得了较高的信噪比及分辨率地震资料。
The Jizhong exploration area in Huabei Oilfield features in complicated deep structure,variable near surface structure,numerous large obstacles,and severe interference environment.So it is extremely difficult to conduct seismic data acquisition here.Restricted by techniques and equipments,the quality of data acquired in the early stage was poor.In recent years,the techniques including the optimization of observation parameters based on pertinent design,the reasonable implementation in the field,the fine investigation of near surface structure,the roll-along design of excitation parameters,the environment noise suppression,and the quality analysis of grid data have been applied to the high-precision 3D seismic data acquisition. As a result,seismic data with high signal-to noise ratio and high precision have been acquired.
