Abstract: The wide-azimuth and high-density seismic exploration technique is widely used at the present time and has gradually become a main trend in the exploration sector. The processing methods for 5D seismic data have been well developed but the corresponding interpretation methods are still in the preliminary stage. The traditional software is not able to analyze 5D seismic data. Aiming at development of wide-azimuth and high-density seismic interpretation technique family, Bureau of Geophysical Prospecting (BGP), CNPC, has created GeoEast-Easy Track (ET) interpretation software for 5D seismic data. This interpretation software package has the unique modules for analysis, merger of data, comparison of slices, imaging of geological bodies, carbonate rock carving, interpretation of 5D data and interpretation of frequency, breaking the bottlenecks of loading, saving and calculating and displaying for the TB-level data. It perfects the company’s key seismic exploration technique series and becomes unique in three areas of software platform, 5D pre-stack interpretation and industrialization of carbonate rock reservoir recognition. As the company’s unique interpretation software platform, it has been widely used both at home and abroad. When used in Tarim Oilfield, it helped improve precision of fractures by more than 20 percent and drilling success by more than 10 percent, solving the complicated geological problems in China and playing an important role in improving oil and natural gas exploration and development success.

Key words: 5D interpretation, wide-azimuth, mass data, carbonate rock fracture-carving recognition

摘要： 目前宽方位、高密度地震勘探技术广泛被油公司接受, 逐渐成为主流。针对宽方位地震资料的五维地震 处理技术已经基本成熟, 但解释技术还处于起步阶段, 商业地震解释软件不具备五维地震解释能力的现状, 中国石油 集团东方地球物理勘探责任有限公司以打造宽方位高密度地震解释技术系列为目标, 形成了面向五维地震数据的Geo- East-EasyTrack 解释软件。该解释软件包含属性分析、数据融合、切片对比、地质体成像、碳酸盐岩雕刻、五维解释、 频率解释等特色模块, 突破了TB 级叠前数据的加载、存储、计算和显示瓶颈, 在软件平台、五维叠前解释和碳酸盐岩 缝洞雕刻工业化3 个方面形成了特色技术, 丰富了公司地震勘探关键技术系列, 成为公司的特色解释软件平台, 在国 内外得到了广泛应用, 通过塔里木油田应用对比, 综合裂缝精度提高20%以上, 钻井成功率提高10%以上, 在解决中 国复杂的地质问题、提高石油天然气勘探开发成功率方面发挥了重要作用。
