1 山区地震资料采集技术“八五”期间,采集参数计算机辅助设计、山区测量、山区提高分辨率资料采集技术和转换波勘探均有新进展;浅层勘探技术和现场处理技术进步较快。2 高陡构造资料处理解释及山区静校正技术多年来在消化引进技术的基础上针对山区、高陡构造特点,积极开发先进技术,如非正规观测系统、不等道距、拟弯线资料处理的预处理和选排技术;静校正、去噪、叠加、偏移及特殊处理技术等。“八五”期间共编制数十个软件,其中以射线变速深度偏移、串级深度偏移软件及CFW静校正技术处理效果最好。3 储层横向预测技术“八五”期间,针对四川的地质特点和储层特点,开发以碳酸盐岩储层及其缝洞发育带为主要预测目标的技术,包括以高分辨处理为基础,提取储层物性参数,直
1 Mountain seismic data collection technology During the “Eighth Five-Year Plan” period, new advances were made in computer-aided design of acquisition parameters, mountain surveying, mountain resolution data collection technology and conversion wave exploration. Shallow layer exploration technology and on-site processing technology improved rapidly. 2 High-steep tectonic data processing and interpretation and mountain static correction technology Over the years, based on the digestion and introduction of technologies, aiming at the characteristics of mountainous and steep structures, advanced technologies such as non-formal observation systems, unequal-distance and quasi-curved line data processing Pretreatment and sorting technology; static correction, denoising, stacking, offset and special handling techniques. During the “Eighth Five-Year Plan” period, a total of dozens of softwares were compiled, of which the best effect was achieved by using ray-shift depth migration, tandem depth migration software and CFW static correction technology. 3 Lateral Reservoir Prediction Techniques During the Eighth Five-Year Plan period, based on the geological characteristics and reservoir characteristics of Sichuan, technologies that mainly target carbonate reservoirs and fractured vugs are developed, including those based on high-resolution processing , Extract reservoir physical parameters, straight
