APPLICATION OF MARINE MULTI AZIMUTH FUSION SEISMIC TECHNOLOGY IN YB OILFIELD OF THE EASTERN ZHUJIANGKOU BASIN
-
摘要:
针对珠江口盆地东部YB油田当前面临的高含水生产之压力，海上常规单方位拖缆地震资料难以满足对油田深层及周边滚动油气田开发目标的评价，故开展了海上多方位融合地震技术攻关。本次采取的主要技术方法是通过不同方位的三维二次地震采集，提高地下反射界面覆盖次数，增大地下反射点时距曲面能量面积。实践证明，海上多方位融合地震技术在研究区具有更好地压制采集脚印、提高信噪比、增加勘探目标照明度和改善地震资料成像品质等优势。研究结果表明, 海上多方位融合地震技术能够支持该油田现阶段稳产及推动周边的储量发现。
Abstract:Compared to conventional offshore streamer seismic technology, marine multi azimuth fusion technology has suppressed the acquisition footprint to improve signal-to-noise ratio, increase the illumination and improve the quality of seismic data imaging as well as other advantages. And the marine multi azimuth fusion technique can be easily realized with conventional offshore seismic streamer equipment only. Aiming at the high water cut and the production pressure in the late stage of YB oilfield and the difficulty for evaluating oilfield target in the east of the Pearl River Mouth Basin, the multi azimuth fusion seismic technology was suggested. It is proved by application that the multi azimuth fusion seismic technology is more favorable for the stable production of the oilfield and the discovery of the surrounding reserves.
