17、ZE3K1V6V3N2-地震勘探实验报告四、主要步骤1.在物探楼后,从东至西开始布置 36 道检波器,道间距为 1m,用两台地震仪相连进行数据采集与接收;2.用铁锤敲击放炮,检波器接收记录,并观察地震记录,若发现有错误道,相反道进行相应测线位置道的检波器检查,直至所接收的地震记录良好(性噪比较好,在 30-60db 范围内前段时间资料平坦无波动);3.完成上述步骤后,首先观测未激发震源时的地震记录,观察随机干扰波;4.放炮,观察地震记录,观察声波,面波,直达波,折射波以及高能干扰的范围位置及形态;5.根据面波,折射波,反射波的出现位置选择最佳窗口然后依据最佳窗口使炮点移动来进行相应的反射波与面

18、波勘探从而得到明显的反射波与面波;6.(实验二内容)6、1 简单连续观测系统设计简介:单次覆盖观测系统:双边激发、单边激发、中间激发、间隔单次覆盖。如果震源固定在排列的一端激发,每激发一次,排列沿测线方向向前移动一次(半个排列长度),这种观测系统叫做单边激发(或叫单边放炮)简单连续观测系统。如果震源位于排列中间,也就就是在激发点的两边安置数目相等的检波器同时接收,这种形式的观测系统称为中间激发观测系统(或叫中间放炮观测系统)。简单连续观测系统的最大特点就是接收段靠近激发点,能避开折射波干涉,便于野外施工,但受面波与声波干扰较大。简单连续观测系统（a）双边激发;(b)单边激发;(c)中间激发;(

33、次要高,不过俩次实验测得的数据基本一致,我们可以瞧出首波均很明显,均在 13 道左右发生转折,我们可以判断,在这之前的首波为直达波,在这之后的首波均为速度更大的折射波,因此我们在折射波勘探中要考虑到观测窗口的大小对实验的影响,要求最小炮检距要大于十三道的位置,即大于转折点对应的炮检距,这样便压制了直达波对地震勘探的影响。6、3 双边放炮、中间放炮观测对比:图(3)正向追逐炮图(4)反向追逐炮文档编码:CL5O9E1X3Z5 HH4R1Z3M4J2 ZE3K1V6V3N2文档编码:CL5O9E1X3Z5 HH4R1Z3M4J2 ZE3K1V6V3N2文档编码:CL5O9E1X3Z5 HH4R1Z

40、3M4J2 ZE3K1V6V3N2-地震勘探实验报告图(5)中间放炮从图(5)中我们可以瞧到在中间激发时,我们可以同时观测到炮点俩侧的地震数据,具有宏观对称性,这样在一定程度上避免了因炮点与检波点相距太远导致能量衰弱的现象。从图(3)与图(4)中我们可以清楚地辨别各种波形,从反向追逐炮中明显地瞧到前面有几道可能就是在移动炮点时碰到了检波器,使检波器出了些问题,但就是对整体影响不大。我们可以瞧到下图所示的情况:在折射波法地震勘探中,比较流行的就是采用相遇追逐观测系统。O1就是 O2的追逐炮,O4 就是 O3的追逐炮;若测线方向为 O1 O4方向,则 O1称为正追逐炮,O2称为正相遇炮,O3 称为

41、反相遇炮,O4 称为反追逐炮。追逐炮的作用:(1)可以利用追逐时距曲线与相遇时距曲线的平行性延长解释区间;文档编码:CL5O9E1X3Z5 HH4R1Z3M4J2 ZE3K1V6V3N2文档编码:CL5O9E1X3Z5 HH4R1Z3M4J2 ZE3K1V6V3N2文档编码:CL5O9E1X3Z5 HH4R1Z3M4J2 ZE3K1V6V3N2文档编码:CL5O9E1X3Z5 HH4R1Z3M4J2 ZE3K1V6V3N2文档编码:CL5O9E1X3Z5 HH4R1Z3M4J2 ZE3K1V6V3N2文档编码:CL5O9E1X3Z5 HH4R1Z3M4J2 ZE3K1V6V3N2文档编码:CL

48、激发点与接收排列,对地下界面反射点多次重复采样的观测形式叫多次覆盖观测系统。多次覆盖观测系统与简单连续、间隔连续观测系统的区别就是移动激发点与接收排列的距离较短,可以重复观测地下界面。对地下界面重复观测多少次就称为几次覆盖。多次覆盖观测系统炮点移动距离与覆盖次数与地震仪器的接收道数满足:NSnv2式中 表示炮点每次移动几个道间距;n 就是地震仪器的接收道数 ;N 就是覆盖次数;S=1表示单边放炮;S=2 表示双边放炮。本次实验所采用的就是六次覆盖,道数选择12 道,单边放炮,我们可以据此算出 =2;因此我们从零炮检距位置开始依次隔俩个道激发一次,相应的电脑文档编码:CL5O9E1X3Z5 HH
