南孟潜山是一个经过长期勘探的老油田,三维地震的重新处理运用了叠前深度偏移技术,通过相干反演等方法求准了层速度,实现了共深度点叠加,使处理结果有所改观。处理后新剖面信噪比明显提高,潜山面反射清晰,内幕结构更清楚,断层清晰,同相轴连续性好,波组特征明显,可解释性强,主要目的层位和区段反射特征清楚。用新处理的三维资料解释结果,分别落实了府君山、龙山、雾迷山组顶面的构造,综合研究发现老井并未控制府君山组油藏的高点,并且龙山的构造也存在很好的圈闭,这是老资料未能发现的。根据地质综合研究结果,部署了滚动勘探井位,钻探后扩大了府君山组的含油面积,发现了新的含油层位——龙山组油藏,取得了潜山内幕勘探的新突破。
Nanmeng buried hill is an old oil field after long-term exploration. The pre-stack depth migration technique is applied to the re-processing of 3D seismic data. The layer velocity is obtained through coherence inversion and other methods. . The signal-to-noise ratio of the new profile after the treatment is obviously improved, the reflection of the buried hill surface is clearer, the inner structure is clearer, the fault is clear, the continuity of the phase axis is good, the wave group has obvious features and strong interpretability, and the main purpose is clear . According to the results of three-dimensional data processing, the top structures of Fujunshan, Longshan and Wumishan formations are implemented respectively. Comprehensive study shows that the old wells did not control the high point of the Fujunju group reservoirs, and the structure of Longshan also exists Good traps, this is the old data failed to find. According to the result of geologic comprehensive study, the rolling exploration well was deployed. After drilling, the oil area of Fujun Mountain Group was enlarged and a new oil reservoir-Longshan Formation reservoir was discovered. New breakthroughs in the exploration of buried hill were obtained.
