靖海凹陷位于珠江口盆地潮汕坳陷以南, 是洋陆过渡壳上的中-新生代叠合凹陷, 作为近几年新划分的构造单元,其中生界地质特征和油气勘探潜力评价是当前研究的重点.该区受岩浆活动影响, 地震资料品质较差, 很难利用现有资料完成构造解释研究进而评价凹陷勘探潜力.通过处理解释一体化的技术思路, 重点运用叠前信噪比技术、子波处理技术和偏移成像技术对该区进行针对性攻关处理, 处理效果达到了构造解释的要求.实践表明该技术在靖海凹陷的实践是成功的, 对于研究靖海凹陷结构和规模及其周缘凸起结构起到了重要的作用.

Jinghai Sag is located south of Chaoshan Sag in the Pearl River Mouth Basin, which is a Mesozoic and Cenozoic superimposed sag in the ocean-continent transition zone.As the new division of tectonic units in recent years, Jinghai Sag is the focus of current research in terms of Mesozoic geological characteristics and hydrocarbon exploration potential evaluation. This area is influenced by magmatic activity and has low-quality seismic data; it is difficult to use the current data to complete the structural interpretation research and evaluate sag exploration potential.In this paper, we used the integration of processing and interpretation techniques. We focused on using prestack SNR technology, wavelet processing and migration imaging technology to carry out test processing in this area. The processing effect was achieved by structural interpretation. The application showed that the technology used in Jinghai Sag was successful, and played an important role in studying structure and scale of Jinghai Sag and its adjacent area.
