以李粮店矿井工业广场新近系流沙层探测与研究为例,总结了全数字高密度三维地震勘探技术在查明新近系松散沙层和隔水层的的空间水力联系、确定井筒透水溃沙形成的充水空洞,判断新近系沙层结构变化及透水溃沙影响范围方面的应用效果,取得了突破性技术成果。
Taking the exploration and research of the newly developed strata of the Liyuandian Mine Industrial Square as an example, this paper summarizes the full digital high-density 3D seismic exploration technology to identify the spatial and hydraulic connections between the newly developed loose sand and the aquitard, Formed water-filled voids to judge the application effect of the structural changes of the sand system and the influence range of water-permeability and sand-breakage, and achieved breakthrough technical achievements.
