2014年以来, 随着国际市场原油价格的低迷和高密度地震采集技术的推广应用, 油公司和油服公司面临巨大的采集作业成本压力。地震节点仪器因其适应复杂地表施工、适应灵活观测系统部署、施工效率高、HSE风险小、作业成本低等优势而得以迅速发展, 地震节点采集技术成为国内外地震勘探行业研发和应用的热点之一。此外, 节点仪器比有线仪器价格低, 适应“单点、高密度、大道数”采集技术发展趋势。近年来, 中国石化持续推进节点仪器及节点采集技术的研发与应用。介绍了中国石化地球物理公司研发的第一代、第二代Ⅰ-Nodal节点采集系统性能特点, 总结了节点采集技术在中国石化的应用进展。结合节点与有线仪器混合采集、全节点独立采集以及全节点与激发新技术配套采集等多种作业模式, 展示了其应用效果。与有线采集相比, 节点采集面临着数据无法实时回传、噪声无法实时监控等难题。为适应油气勘探高密度、高效率、低成本施工需求, 节点采集将向小型化、轻量化、低成本化、自动化方向发展。面临高密度、高效率、低成本物探采集技术需求, 节点采集展现了广阔的应用领域和良好的应用前景。
After 2014, with the low crude oil price in the international market and the application of high-density acquisition technologies, oilfield corporations and service companies faced significant cost pressures on their acquisition operations.Nodal instruments have developed rapidly, and have become a hot topic of research and application in the oilfield service industry worldwide owing to their advantages of facilitating easy-access surveys on complex surfaces and their ability to adapt to flexible changes in geometry design, as well as their high operation efficiency, low HSE risk, and low operating cost.Furthermore, the price of nodes is lower than that of cabled instruments, and nodal instrumens can better adapt to the development trend of acquisition technology that is "single point, high density, and amount of channels." In recent years, Sinopec has continuously promoted the development and application of nodal instruments.Herein the performance characteristics of the first-and second-generations of the Ⅰ-Nodal node acquisition systems developed by Sinopec Geophysical Corporation were introduced.Furthermore, the progress in the application of nodal acquisition technology in Sinopec was summarized.The application effect was demonstrated by combining various acquisition modes, such as the hybrid acquisition mode of the node and cable system, the independent acquisition mode of all nodes, and the matching acquisition mode of all nodes and new excitation technologies.The data quality was improved by increasing the number of receiving channels and coverage times.Compared with cabled systems, node acquisition technology faces some problems, such as data cannot be transmitted back in real time, and noise cannot be monitored in real time.To meet the requirements of low cost, high density, and high efficiency in oil and gas exploration efforts, the nodes will be miniaturized, lightweight, cost less, and automated.Moreover, the degree of integration and automation of the node acquisition system will progressively increase.With the development of high-density and high-efficiency acquisition technologies, node acquisition has widespread application fields and good application prospects.
