黄土塬地区地震勘探采集技术研究与应用

Study and Application on Seismic Prospecting and Acquisition Technology in Loess Plateau Area

为解决黄土塬地区地震勘探资料采集过程中存在的问题,以王家岭煤矿为例,通过总结分析以往地震资料及近年来发展的黄土塬区地震勘探系列新技术方法的有效性,在模拟分析和野外试验的基础上,针对不同的采集技术难点和施工难点提出了相应的解决对策,总结了在规则化三维数据观测条件下的黄土塬地震采集技术的系统集成应用方法,值得在类似区域推广。

In orcler to solve the difficulties of the process of seismic data acquisition in the loess plateau area, take the Wangjialing coal mine as an example. Through summarizing and analyzing the past seismic data and the effectiveness of the recent development of the new methods of seismic exnloration in loess nlateau area. the and based on the simulation analvsis and field test. put forward corresponding countermeasures for the difficulties of different acquisition techniques and the construction, and a new technique of stereo combination excitation for suppressing refracted multiples is proposed, and summarize the system integration method of seismic acquisition for loess plateau area under the condition of regular 3D data observation, which is worth popularizing in similar areas.
