电磁阵列剖面法(EMAP)在阿尔凹陷构造研究中的应用

EMAP Application on Study of the Aer Sag Structures in the Erenhot Area,Inner Mongolia

本文论述了电磁阵列剖面法(EMAP)在二连浩特地区阿尔凹陷岩性分层、断裂及基底构造研究中的应用。采用电磁阵列EMAP测量,有效的避免了静态位移难以有效校正等问题。通过有效的资料处理,反映了阿尔凹陷地层结构特征与空间展布,落实了凹陷的基底埋深,对区内控陷断层的位置、性质、展布及发育特征进行了划分,达到了较好的预期效果,为勘探空白区油气远景预测提供了可靠的基础资料。

In this paper, the authors state the EMAP （Electro-Magnet Array Profiling） application in the geological survey of lithological hierarchical, fracture and basement tectonic in the Aer Sag located in Erenhot, Inner Mongolia. It is effective to avoid the problems caused by the static shift which are hardly solved with using EMAP method. And through effective data processing, it could not only display the stratum structure and space distribution of Aer Sag, find the depth of basement of the sag, but also reflect the location, properties, distribution and development characteristics of the faults controlling the sag, and also provide reliable initial data for forecasting the resources prospect in the exploration blank space.
