Application Of Seismic Attributes Technology In The Junggar Chepaizi C3 Wells Volcanic Identification

Seismic attribute is make use of seismic data of before or after stack , by means of mathematical transformation and export of the seismic wave geometry, kinematics, kinetics, and statistical characteristics of measurements. Applications of seismic attributes techniques to identify and predict volcanic rock is a relatively effective methods, but due to the seismic attribute and variety, widely used, but also because of volcanic region and genesis of a variety of reasons and differences, So this thesis in research and application of seismic attributes to identify and predict volcanic is a small block, Junggar Basin Chepaizi raised C3 Wells to identify and predict the volcanic rocks, in order to achieve the expected purpose this.This article was about several aspects of the research work:(1) This thesis from the volcanic seismic attribute analysis based theory, research and analysis on the seismic attribute definition, classification, instructions, geological and geophysical significance .(2) Applied research to identify and predict volcanic seismic attributes, all types of properties are summarized in detail, especially applied to the reaction of volcanic rocks .(3) Of the Junggar Basin Chepaizi raised C3 Wells volcanic seismic data extraction, mainly of several categories of properties, including: amplitude attribute, geometric properties, instantaneous attributes, wavelet properties and spectral decomposition property, etc. Each class attribute contains the attributes of several dozen or even . Extracted from the dozens of attributes and the selection and analysis, the most important is the property of the volcanic rocks to identify and predict the response, integrated response to various properties, to predict volcanic range and regional presence .(4) Comprehensive analysis of previous volcanic properties, given the seismic section and plan on the scope and areas of volcanic rocks.Through the front of the study concluded:Identify and forecast volcanic rocks of Junggar Basin Chepaizi raised C3 Wells, more effective attributes are: rms amplitude, chaotic reflection, dip variance, shale indicator, similarity, instantaneous frequency, instantaneous phase, trace envelope, spectral decomposition property, etc. In future research work, these properties will be applied to other areas identify and forecast volcanic rocks.
