Abstract：Two deep fault zones developed in the Hongxing,Eastern Sag of Liaohe Depression.With multiple eruptions,very well-developed volcanic rocks cause many difficulties in structural interpretation and geological modeling.After structural interpretation and modeling,volcanic reservoir prediction with inversion cannot satisfy the exploration needs.Therefore,we conduct volcanic reservoir prediction with attribute extraction and analysis provided by GeoEast.The boundaries and the spatial distribution of volcanic rocks have been well characterized by the texture attribute.According to our prediction,volcanic rocks in the southern area were well-developed in the shape of blocks or thick layers,and volcanic rocks in the central and northern area were well-developed in the shape of layers.Volcanic rocks show banding distribution at plane,and are in line with the two deep fault zones.It is inferred that the volcanic eruption model was a fissure eruption.Based on this,volcanic reservoirs in E2s3 formation have been predicted after attribute extractions along the horizons.Our prediction with the texture attribute has closely matched with the latter drilling data,which provides reliable references for the future volcanic reservoir exploration in the area.
