摘要
浩然柴达木地区位于杭锦旗西部,区内下白垩统华池—环河组具备较好的找矿潜力。依托2019年完成的5条面积性的CSAMT测深数据,结合地质及钻孔资料,对该地区下白垩统华池—环河组砂体发育特征进行了分析。研究结果表明,区内该组地层砂体十分发育,分布范围较广,顶板埋深200 m左右,厚度400~700 m,局部达750 m,走向NW,整体表现为北东部薄、中部—南西部厚的发育分布特征,为钻探工程的布置提供了深部地质信息。
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.
