摘要
歧口凹陷张东构造带是大港油田扩大潜山勘探领域的重点地区,针对研究区古生界潜山目的层进行了叠前时间高保真地震资料处理。根据碳酸盐岩储层埋藏深,非均质性强,地震资料分辨率低、信噪比低、多次波发育等特点,采用了叠前多域分频去噪、Radon变换+内切除法消除多次波、振幅补偿处理、串联反褶积、迭代速度模型建立和双向聚焦叠前成像等关键技术,提出了一套适合于碳酸盐岩缝洞型储层的叠前时间偏移处理方法和技术流程,极大地改善了该区地震资料的反射品质,为提高张东潜山带碳酸盐岩储层预测和油气检测提供了资料保障。
the Zhangdong structural belt of Qikou depression is an important buried hill exploration area in Dagang Oilfield,the prestack time high fidelity data processing were conducted for the targets of buried hills.According to the features of the carbonate rock reservoir,such as deep reservoir,strong anisotropy,low seismic data resolution,low signal-to-noise ratio and developing multiple,etc,a series of key techniques were applied,such as prestack multi-domain separating frequency removing noise,Radon transform+ internal seiscrop to remove multiple,amplitude compensation processing,ascaded deconvolution,iteration velocity modeling and two-way convergence prestack image,and proposed a set of suitable prestack time migration methods and workflow,the quality of the seismic data were improved in the area,it has provided the quality data to improve the prediction and hydrocarbon detection of the carbonate rock reservoir of the buried hills in Zhangdong area.
