陡倾角地层地震资料解释与成图技术研究与应用

摘要

The article introduces the seismic interpretation and mapping technology in steep dip seam. Reflection layer calibration method was used for complex surface condition in seismic exploration areas in Honghui, Wangjiashan and other mines of Jinyuau Group. Under the condition of sparse drills, Forward Modeling Calculation was used to synthesize the seismic record. The artificial synthesis recording method was discussed under non-sonic logging curves. For rapid change of horizontal velocities in the steep dip seams, the stack velocity mapping was used to achieve better effects in the process of geology （such as fault） structure interpretation.%本文主要介绍陡倾角地层地震资料解释与成图技术，并在靖远矿业集团的红会、王家山等矿区地震勘探区地表条件复杂的地段使用陡倾角地层反射波地质层位的标定方法，在钻孔稀疏情况下应用正演模型计算合成地震记录，重点阐述了在无声波测井曲线条件下人工合成地震记录的方法。在成图技术中，针对陡倾角区地层横向速度变化大的特点，应用叠加速度辅助成图，在断层等地质构造解释过程中取得了较好的效果。
