琼东南盆地深水区具有巨大的勘探潜力,但该区地震资料大多为二维资料,且中深层资料品质普遍偏差,对评价古近系影响较大。处理解释一体化技术在琼东南盆地深水区的实践采用的方法是:以陵水凹陷为例,通过对该区地震资料的品质进行分类分析,优选出可能改善的测线进行针对目的层的试处理,对试处理结果和效果进行分析,最后进行批处理。处理解释一体化达到了提高地震资料品质,进而精细研究和评价圈闭目标直至井位研究的目的。实践表明该方法在琼东南盆地深水区的应用是成功的,对于研究陵水凹陷的内部结构和规模及其周缘的凸起结构起到了重要作用。

There is huge prospect potential in Qiongdongnan basin, but most seismic data of the survey is 2D and poor and it affects e-valuation of Paleogene strata. Therefore, the method of integration of processing and interpretation in deep water is applied in Qiong-dongnan Basin. Taking Lingshui depression as an example, part of the seismic data is selected for reprocessing by classifying seismic data and analyzing the probability of improving the quality of these seismic data through reprocessing, and the result is analyzed to see whether it meets the need of seismic data interpretation and prospect evaluation or not. At last, the seismic data of Lingshui depression and its adjacent area is reprocessed. The quality of seismic ata in this survey is greatly improved by using integration of processing and interpretation which proves that the technique is successful and effective. The seismic data of reprocessing plays very important role in studying the inside configuration and scale of Lingshui depression.
