Abstract

Haoran Qaidam region is located in the western part of Hanggin Banner. According to the analysis of previous work, there exists great potential for prospecting in the lower Cretacteous Huachihuanhe Formation. Based on CSAMT sounding data obtained along five lines in 2019 and combined with geological and drilling data, the authors analyzed the sand body development characteristics of Huachihuanhe Formation. The research results show that the sand bodies in this area are well developed and widely distributed, with a roof buried depth of about 200 m, a thickness of 400~700 m, a local thickness of 750 m, and a NW strike. The overall development and distribution characteristics are thin in the northeast and thick in the middle southwest. The result obtained by the authors provides deep geological information for the layout of drilling projects.

Key words： Haoran Qaidam CSAMT Huachi-Huanhe Formation sand body
