摘　　要：在彬县-长武区块以往资料分析的基础上,结合地质情况特点,通过系统激发和接收试验,进一步明确适合该地区地震勘探的激发和接收参数。阶梯式微测井调查方法,适用于厚黄土塬区,能够提高表层结构调查精度;采用优选激发点的观测系统设计方法,不仅能保证激发能量的均衡,而且还能保证覆盖次数的相对均匀;采用大组合激发方式,可压制表层干扰波,提高地震资料信噪比。Based on the analysis of former data on Binxian--Changwu block and through system shooting and receiv- ing trial combined with geological condition, shooting and receiving parameters suitable for seismic exploration in this region have been further identified. Ladder--microlog survey method suitable for loess yuan region helps enhance survey precision of surface structure. The adoption of recording geometry design method based on optimized shot point can ensure the balance of shooting energy and relative uniformity of folds. Using grand assembly shooting mode helps suppress surface disturbing wave to improve signal to noise ratio of seismic data.
