可控震源单台高密度采集技术及应用效果

摘要/Abstract

摘要： 针对国内勘探区域地表起伏大、部署面积小、目的层埋藏深、地层薄等特点，要求所采集的地震资料具有较高的信噪比和分辨率。利用可控震源激发信号可控的特点，开展了基于陆上可控震源单台高密度采集的攻关试验，同时也是国内第一块低频、多道数陆上地震采集系统野外试验。试验结果表明，该技术可以有效解决目前仪器带道能力和外设装备不足的现实问题，在国内首次实现可控震源单台高密度采集的工业化生产。同时通过技术推广应用，完成了多块三维地震采集工作，并取得了较好的地质效果。

Abstract: The acquired seismic data are required to have high signal-to-noise ratio and resolution because the domestic exploration areas have large surface fluctuations, small deployment area, large buried depth of target layer, and thin layer. Based on the characteristics that the signal excited from the controllable vibrator is controllable, the research and test is conducted on single onshore controllable vibrator high-density acquisition. Meanwhile, it is also the first block for field test of low frequency multi-channel onshore seismic acquisition system. Based on the test results, this technology can effectively solve the problem that the channel capacity of present instruments and peripheral equipment are inadequate. Industrialized production by means of single controllable vibrator high-density acquisition is carried out for the first time at home. Meanwhile, this technology helps complete 3D seismic acquisition work in a number of blocks, achieving good geological results.
