胜利油田高精度地震勘探采集技术及应用实例
|
摘要
随着勘探的不断深入,常规地震采集技术已不能满足油气田开发的需要,高精度三维地震采集技术得到了迅速的发展。在胜利油田勘探开发实践中,发展了一套针对复杂地质目标的高精度采集技术。在理论上,从观测系统设计、震源激发、检波器接收、噪音压制等方面对高精度地震采集技术进行了系统的描述;在实际应用方面,针对胜利油田的田家地区、罗家地区、四扣地区和渤深6地区的不同地质目标和地质任务,从采集工艺上详尽地分析了所采用的方法和措施。对取得的地震资料,采用新老剖面对比的方法,分析了高精度采集技术的应
Conventional seismic acquisition technologies fail to meet the demands of oil-gas field development, which leads to the rapid development of high precision 3D seismic acquisition technology. In the exploration and development practice in Shengli Oilfield, a suite of high precision acquisition techniques has been developed. This paper theoretically described the aspects of high precision acquisition technology, such as layout design, shooting and receiving conditions, noise suppression. The applications of high precision acquisition technology were illustrated in terms of geological setting, geological objective, and acquisition technology, by the case histories of Tianjia area, Luojia area, Sik-ou area and Boshen 6 area in Shengli Oilfield. The effectiveness of the technology was analyzed through a comparison between new and legacy sections.
