Abstract

The invention provides a method for depicting volcanic space distribution based on amplitude-variance cube seismic attributes. Strong amplitude three-dimensional seismic data are picked up to obtain volcano overflow phase data; meanwhile, volcanic vent phase data are picked up according to variance cube data, the volcanic vent phase data and the variance cube data are fused to complete the fusion depicting of an overflow phase and a vent phase. According to the method for depicting volcanic space distribution based on the amplitude-variance cube seismic attributes, the overflow phase and the volcanic vent phase are fused and displayed, three-dimensional display is achieved, and the space distribution of volcanic is visually and vividly depicted; the overflow phase and the volcanic vent phase are the two most important subphases of the volcanic, the prediction studies of a volcanic reservoir is facilitated through the fusion and display of the overflow phase and the volcanic vent phase, and the method can be widely applied to petroliferous basins related to the volcanic and especially applied to depicting of the space distribution features of the volcanic, analysis of the influences of the volcanic on the surrounding reservoirs and the control function of the volcanic activity on oil and gas accumulation.

Description

technical field [0001] The invention relates to a method for describing the spatial distribution of volcanic rocks based on seismic attributes of amplitude-variance bodies, and belongs to the field of petroleum exploration and development. Background technique [0002] For petroleum basins where volcanic rocks are developed, volcanic rocks have an important influence on the transformation of reservoirs and accumulation. However, due to the complex structure and severe lateral changes of volcanic rocks, different types of volcanic rocks develop in different structural parts and have different seismic reflection characteristics. How to effectively identify the spatial distribution characteristics of two diametrically opposed seismic reflection characteristics of weak amplitude has always been a difficult problem. Aiming at related technical problems, scholars at home and abroad have proposed many solutions. Andrew Miles et al. (2010) identified the distribution of phyllovolc...
