油气储层潜能的太赫兹光谱研究

Oil and gas resource is the main energy in the industrial and social development process, and the exploration of oil-gas resources depends on the accurate evaluation of the oil-gas reservoir potential. The oil and gas resources have been exploited to a certain extent nowadays, and the oil-gas reservoir presents many new characteristics so that the traditional methods cannot meet the increasing needs of technology characterizing and evaluating the oil-gas potential. Terahertz (THz) spectroscopy bridges the gap between the microwave and infrared with the high signal-to-noise ratio, time-resolution and safety features. In this project, the research is of great significance because of the national demand of technology evaluating the oil-gas reservoir potential. The interaction mechanism between terahertz radiation and oil-gas reservoir will be initially studied based on our existing work. All the aspects of oil-gas reservoir potential evaluation will be considered and explored in depth, including geological evolution, the surface layer of the desert sand, pore structure, adsorption dynamics, oil rate of shale and the pyrolysis process as well as products of oil shale. Then the THz fingerprint database will be established related to the potential of oil-gas reservoir. Combined with mathematical statistical methods, new principles and technologies will be obtained about the evaluation of oil-gas reservoir potential with the independent intellectual rights.

油气资源是现代工业和社会发展过程中的主要能源，油气资源的勘探开发源于油气资源潜力的准确评价。在油气资源已被开发利用到一定程度的今天，油气储层呈现出许多新的特点，传统的方法已不能完全满足油气储层潜力表征与评价过程中不断增长的技术需求。太赫兹光谱在电磁频率上衔接了微波与红外之间的间隙，具有信噪比高、时间分辨率高、安全等特点。本项目针对国家油气资源勘探开发对光学新技术的重大需求，研究太赫兹波与油气储层物质的相互作用机制，对地质演化、沙漠表层沙样、储层岩石孔隙结构、吸附、油页岩含油率、油页岩热解过程及产物等涉及油气储层潜力评价的各个方面进行综合表征，发展太赫兹计量学方法，提高油气储层潜能表征评价技术的多样化和高效化，解决热解、地震波等传统方法难以实现或成本高、效率不高的实际问题，期望太赫兹光谱能成为油气储层潜能表征技术的有效补充，为油气资源潜力评价提供具有自主知识产权的新原理和新方法。
