【摘要】：随着浅部找矿难度的增加,金属矿的勘探将进一步向深部进军.受勘探深度与精度的限制,常规地球物理勘探技术难以准确刻划深部金属矿控矿结构.作为深部探测的核心技术,反射地震技术具有探测深度大、分辨率高等特点,正逐步成为解开深部构造矿床勘探难题不可或缺的重要手段.本文回顾了近年来反射地震技术在深部金属矿勘探中的取得的重要进展,包括了岩石物性基础、三维地震技术、井中地震技术以及正演模拟等方面.这些事例表明,反射地震技术在金属矿勘探中具有很高可行性与广阔的应用前景.然而,相比于油气行业,现阶段金属矿反射地震勘探无论在岩石物性测量还是数据采集、处理与解释等方面都存在着明显的不足,还需要不断地认识和改进.最后本文就金属矿反射地震勘探应用中存在的这些问题提出了该技术进一步发展的主要方向,旨在为我国典型成矿带深部金属矿勘探工作提供一些借鉴.
[Abstract]:With the increasing difficulty of shallow prospecting, the exploration of metal ore will move further into the deep.Due to the limitation of exploration depth and precision, conventional geophysical exploration techniques are difficult to accurately characterize the ore-controlling structure of deep metal deposits.As the core technology of deep exploration, reflection seismic technology has the characteristics of large depth of exploration and high resolution, which is becoming an indispensable and important means to solve the difficult problem of deep structural deposit exploration.This paper reviews the important progress made in the exploration of deep metal deposits by reflection seismic techniques in recent years, including the physical properties of rocks, three-dimensional seismic techniques, in-well seismic techniques and forward modeling.These examples show that the reflective seismic technique has high feasibility and broad application prospect in metal ore exploration.However, compared with the oil and gas industry, at present, there are obvious shortcomings in the seismic exploration of metal ore reflection, such as the measurement of rock physical properties, data acquisition, processing and interpretation, etc., which need to be continuously recognized and improved.Finally, this paper puts forward the main direction of further development of this technology in the application of reflected seismic exploration of metallic ore deposits, in order to provide some references for the exploration of deep metallic deposits in typical metallogenic belts in China.
