辽东湾北部滩海地区地下蕴藏着丰富的油气资源,勘探程度低,勘探潜力大,是辽河油田重要的产能接替区[1]。但是,滩海地区地表环境复杂多变,地震采集涉及气枪、炸药、水检、陆检等多种激发接收组合类型,导致不同区域地震资料在能量、相位、极性等方面差异很大,同时该区多次波干扰强烈,严重降低地震资料的信噪比,制约该区基岩潜山勘探。因此,如何有效提高滩海地震资料品质,对进一步深化滩海勘探具有非常重要的意义。 In the northern part of Liaodong Bay, there are abundant oil and gas resources underground in the beach area, with low exploration degree and great exploration potential, which is an important succession area of ​​productivity in Liaohe Oilfield [1]. However, the surface and sea environment in the beach area is complex and changeable. The seismic acquisition involves many kinds of excitation and reception combinations such as airguns, explosives, water inspection and land inspection, resulting in great differences in energy, phase and polarity of seismic data in different areas. Meanwhile, The multiple interference in this area is intense, which severely reduces the signal-to-noise ratio of seismic data and hinders the exploration of bedrock buried hills in this area. Therefore, how to effectively improve the quality of beach-sea seismic data is of great significance to further deepening beach exploration.
