摘　　要：三维地震技术是致密油气藏勘探开发的关键技术,科学的地震采集、工程方案与组织管理是取得高品质地震资料的保障。以杭锦旗地区南部独贵加汗三维工区为例,从勘探中的关键地质问题、地震资料采集和工程施工等难点入手,制定了针对复杂地区三维地震采集、工程施工与组织管理方案。结果表明:(1)杭锦旗南部地区成藏主控因素是储层物性和源储配置关系,优势储层预测和岩性圈闭含气性评价是三维地震必须解决的关键地质问题;(2)"六统一"的三维地震施工方案与组织管理形式成功实施了陆地面积三维地震整体采集,取得了高品质的无痕连接的地震资料,可以为类似地区的三维地震采集提供借鉴。3-D seismic technology is the key technology in the exploration and development of tight oil and gas reservoir. The scientific seismic acquisition, engineering project and organization management are the guarantee of the high quality seismic data. Duguijiahan 3-D seismic area in Hangjinqi southern as an example, from the key geological problems in exploration, seismic acquisition and construction, and other difficulties of formulation for complex area 3-D seismic acquisition, engineering construction and organization management scheme. The results show that,（1）the main controlling factors of gas accumulations in south of Hangjinqi area was the physical property and the relationship between origin and reservoir. The reservoir prediction and evaluation of gas-bearing property was the key geological issues which have to been solved by 3-D seismic.（2）The large-area 3-D seismic was been acquisited integrally by the construction method and organization form based on ＂unified construction design, unified surface modeling, unified quality standard, unified device management, unified team management, unified construction organization＂. In this way, high quality and seamless connection of seismic data can be obtained, which can provide reference for 3-D seismic acquisition in similar area.
