摘　　要：大港探区海域属于滩涂地带,地表条件较深海域更加复杂。随着陆上油田勘探开发程度的不断深入,剩余资源潜力逐渐减少,具有丰富油气资源的滩海区域逐步成为大港勘探重点区带。近年来,通过深化研究与探索实践,解决了大港滩涂区特殊的环境和海况条件下"陆上设备下不去、海上设备上不来"的难题,逐步形成了适合滩涂区域的地震地质、海洋工程建设以及钻完井等配套技术系列,并实现了高效开发。技术系列包括地质研究领域拓展应用地震一体化采集处理、精细构造解释、储层预测等关键技术;海洋工程建设领域创新形成环保型"实体"结构进海路、"透流"结构进海路、滩海域人工岛建设、滩涂区钻井平台建设等特色配套技术;钻完井领域集成应用磁感应防碰绕障、大斜度井、大位移水平井优快钻井、单筒双井井口槽利用等"井工厂"模式高速高效钻完井配套核心技术。这些油田建设配套技术及特色技术应用为大港滩涂区域油田优质高效开发提供重要技术保障,同时为类似油田建设开发提供技术借鉴。Dagang offshore exploration oilfield attributes to shoal area,where surface conditions are more complicated than deep sea.With the continuous exploration and further development of onshore fields,the potential of residual resources is gradually decreasing.Thus,the shoal area with abundant oil and gas resources has gradually become the key exploration area of Dagang.In recent years,deep research and exploration have been conducted to solve the difficulties of onshore and offshore equipment moving constraints under the special environment and marine conditions of Dagang shoal area.A series of applicable supporting technologies are gradually developed,such as seismic geology,marine engineering and construction,drilling and completion,thus realizing the high efficiency development.The key technologies involve the integrated seismic acquisition and processing,fine seismic structural interpretation and reservoir prediction,used for expanding the geological research field.The special supporting technologies are developed innovatively during offshore construction in the shoal area,involving environment-friendly solid-structure road through island,through-flow structure oversea road,artificial island and drilling platform.The integrated core technologies involving anti-collision magnetic induction,high deviated well,long extended reach horizontal well high-speed drilling and single-cylinder double well are developed and applied in well drilling and completion with high speed and high efficiency.The application of supporting and special technologies provides an important technical guarantee for the high quality and efficient development of oilfields in the Dagang shoal area,and also a technical reference for the development of similar oilfields.
