Description
本发明属于地球物理勘探领域的综合地球物理勘探技术领域，具体涉及一种集成地震波场、电场、磁场的多勘探地球物理场并行采集系统，实现非同场源的综合物探技术。
地球物理勘探是通过不同地质体的物理属性差异，探测不同地质体与异常体的勘探技术与方法，地球物理勘探仪器(简称物探仪器)是地球物理勘探的核心，物探仪器是以地球物理勘探理论为基础，结合传感技术、数据采集技术及计算机技术等多学科技术的融合而形成的专业仪器。地球物理勘探按照物理场源的不同，一般分为地震勘探、电法勘探、电磁法勘探、重力勘探、磁法勘探和放射性勘探等。还可以进一步细分，如地震勘探可以分为主动源及被动源地震勘探；电法勘探可以分为电阻率勘探与激电勘探；电磁法勘探可以分为瞬变电磁勘探、无线电波透射勘探及大地电磁勘探等。每种物探方法均有对应的仪器设备，导致综合物探时所需的设备多、线缆复杂，不同物探方法要先后施工，不仅制约了综合物探的现场实施效率，而且造成各物探方法在采集时空分离、时间分辨率降低。
现有的物探设备中，一般只能同时实现同源场的综合物探，如地震勘探的反射波、折射波及地震面波同时勘探；电法勘探中电阻率法、激发极化法和自然电场法的同时勘探。要实现不同源、多地球物理场勘探，需要复杂的多种物探装备，装置类型复杂，施工效率低。不同源的综合物探具有场源响应的正交性，如震电勘探是指震源激发下的电响应，与震源作用下的地震信号不相关，震源激发下的电信号与震信号具有正交性，这一正交属性具有评价地层渗透性 的作用，是目前非常规能源勘探的热点问题；类似的电震勘探，目前还在探索中。
时不变系统物理上代表结构和参数都不随时间变化的一类系统。严格地说，由于内部影响和外部影响的存在，时不变系统只是时变系统的一种理想化模型。但是，只要这种时变过程比之系统动态过程足够地慢，那么采用时不变系统代替时变系统进行分析，仍可保证具有足够的精确度。传统物探也假设探测对象为时不变系统来简化，但对于正在受工程施工影响较大的探测目标来讲为时变系统，能够适应时变系统进行同源和非同源的综合地球物理勘探装备具有重大创新意义，是物探新方法、新装备的源头。
