【摘要】 工区位于在大民屯凹陷荣胜堡-前进地区工业繁华地带,地表水系发育,表层岩性复杂,深层各种油气藏圈闭类型众多,勘探难度大,以往采集资料质量差。本文详细介绍了为改进资料质量所采取的一系列措施,其中包括科学的观测系统设计、认真细致的表层调查、高精度的测量,选择最佳岩性组合激发、低噪声接收、大型障碍区特观施工、定量化质量控制等工作。成功地进行了二次三维采集,实现了二次采集资料质量的飞跃,减少浅层资料缺失,保证了深层资料品质,保证了资料解释的准确性。文中展示了了实际效果。更多还原

【Abstract】 The working area is located in the industrially developed region of Rongshengpu- Qianjin, where a surface water system is developed, surface-layer lithology is complicated, and various kinds of hydrocarbon traps are buried at depth. The seismic data acquired previously couldn’t be interpreted due to the complex surface and geological conditions. Taking secondary 3D seismic from the Rongshengpu-Qianjin area as an example, this paper describes a set of techniques designed to overcome these difficulties and improve the quality of seismic data. The applied techniques included flexible acquisition geometry, low-noise receiver conditions, quan- titative quality control, and so on.更多还原
