摘要
南堡1号构造位于南堡凹陷的西南斜坡带上,紧邻南堡凹陷的重要生油中心,其中浅层构造规模大,构造背景好,有利圈闭多,但是火成岩多期次广泛发育,屏蔽严重,岩下和通道成像困难,不确定性高,增加有利圈闭和火山岩精细识别的难度,直接影响勘探开发的部署.为解决高陡倾角成像问题,在GPU和存储设备的高速发展下,油田首次引入逆时偏移技术,在叠前精细处理的基础上,逆时偏移取得较好的成像效果,能量归位好,成像精度高,目的层信噪比、分辨率明显提高,在此基础上,开展的构造与储层的研究成果形成新的油气成藏模式,并取得较好的勘探开发效果.
Nanpu 1st structure is located in the southwest slope belt of Nanpu Sag depression,which is adjacent to the important oil source center of Nanpu Sag.It has the large shallow structures range,good tectonic setting and many favorable traps.However igneous rock developed repeatedlyand widely,which caused shielding seriously,rock and channel imaging difficultly and high uncertainty of the deployment in exploration and developing.In order to solve the problem of high steep dip imaging,with the high speed development of GPU and storage device,we firstly introduce reverse time migration（RTM） technology.Based on prestack fine processing,the result of RTM is better for good energy migration and high imaging precision.Which increased obviously the signal-to-noise ratio and resolution ratio of objective layer.On this basis,we carry out the study structure and reservoir and formed the new Oil and gas accumulation model,finally the result of exploration and developing is good.
