传统的有线地震资料采集技术发展至今,形成了“高密度观测+可控震源高效采集”的有线仪器地震采集技术,在国内各个探区得到了广泛应用并取得较好效果,但在施工中暴露出有线仪器排列容易中断、复杂工区布设困难、效率提升难、高密度采集成本高等问题。为克服有线仪器带来的一系列问题,引入无线节点仪器,开展了无线节点现场实施技术、可控震源生产控制(VPM)系统高效采集技术和质控技术等方面研究,形成了无线节点采集技术序列。该技术在准噶尔盆地页岩油高分辨率勘探和山前复杂构造勘探中的应用结果表明,无线节点采集技术生产日效比有线采集技术提升了50%以上,是一种可以提升中浅层分辨率和深层构造成像的最新地震采集技术。该技术在成本基本不变的条件下,采集的资料品质得到了提升,推广前景广阔。
Traditional wired seismic acquisition technology is now mature,providing high-density observations and vibration-efficient acquisition.This technology has been widely used in various areas in China and provides accurate results.However,this technology still experiences some problems:the wired instrument arrangement is easily interrupted,the layout in complex areas is challenging,improving efficiency is difficult,and the cost of high-density acquisition is high.To address these problems,in this study,we constructed a wireless node instrument,implemented it in the field,developed an efficient vibrator production control system (VPM) for acquisition and quality control,and finally designed the technology supporting the wireless node.Through the application of this system to the high-resolution exploration for shale oil in the Junggar Basin and the imaging exploration of complex piedmont structures,we proved that the daily production efficiency of wireless node acquisition technology is more than 50% higher than that of wired technology,providing higher deep-structure imaging resolution of the medium and shallow layers.This technology improves the quality of the obtained seismic data without notably increasing cost,so has broad prospects for practical applications.
