Interpretive processing techniques contribute to the discovery of the first volcanic reservoir in the eastern South China Sea Available to Purchase

Volcanoes are widely developed around Dongsha massif in the Pearl River Mouth Basin in the South China Sea. in view of the fact that there is no study on volcanic rock accumulation in this area, interpretive processing techniques (frequency division reconstruction + diffusion filtering technique and 3D edge enhancement technique) are applied to improve the resolution of seismic data near the Neogene basement. Based on the reasonable prediction of the location of source rocks of Neogene Wenchang formation and the interpretation of the interface between volcanic rocks and intrusive rocks, it is concluded that volcanic rocks have the possibility of reservoir formation. Through the drilling result of well H1, 491 m andesite was drilled, the oil and gas shows 4 layers of 392 m, and the logging interprets 17 layers of 115 m. The scale of reserves is close to that of medium-sized oil and gas fields. The discovery of the first volcanic reservoir in the eastern South China Sea has opened up a new field for the study of volcanic rock accumulation in the South China Sea, which plays an important role in the understanding of volcanic rock structure and the study of reservoir-forming rules in the South China Sea.
