复杂地区电磁法勘探远参采集系统的应用

近年来，连续电磁剖面法（CEMP）在西部复杂山区的油气勘探应用效果日益突出，特别是在地震勘探困难区，油气电磁法勘探技术已成为首选的非地震勘探技术之一。在复杂区开展电磁法勘探工作，主要得力于电磁法采集系统的发展和技术进步，特别是便携式采集系统的出现和GPS卫星同步控制技术的应用。该文主要介绍无线网络式CEMP远参采集系统，远参采集技术及应用。

Application of Acquisition system with remote reference in complex area for electro-magnetic exploration

In recent years, effect of application of continuous electro-magnetic profile method (CEMP) in complex mountainous area in west China, especially the areas which is difficult for seismic exploration, for oil and gas exploration has been becoming increasingly prominent. Techniques for electro-magnetic exploration for oil and gas have become one of the indispensable priority in that of non-seismic exploration. Moreover, EM exploration in complex area benefits from development of acquisition system of EM as well as improvement of related techniques, in particular, the appearance of portable acquisition system and application of satellite synchronization of GPS. In this paper we will introduce CEMP acquisition system with remote reference in the form of wireless network, techniques for remote acquisition as well as its application.
