Seismic facies and attributes analysis techniques are introduced. The geological characteristics of some oil fields in western China are used in conjunction with drilling results and logging data to identify the lithology, intrusion periods, and distribution range of the Permian igneous rocks in this area. The lithologic classification, the vertical and horizontal distribution, and the intrusion periods of igneous rock were deduced through this study. Combining seismic facies and attributes analysis based on optimization can describe the igneous rock in detail. This is an efficient way to identify lithology and intrusion periods. Using geological data and GR-DT logging cross-plots the Permian igneous rock from TP to TT was divided into three periods. The lithology of the first period is tuff and clasolite with a thickness ranging from 18 to 80 ms. The second is basalt with a thickness ranging from 0 to 20 ms. The third is tuff and clasolite and dacite whose thickness ranges from 60 to 80 ms. These results can help understand the clasolite trap with low amplitude and the lithologic trap of the Carboniferous and Silurian. They can also guide further oil and/or gas exploration. © 2012 Published by Elsevier B.V. on behalf of China University of Mining and Technology.

This paper introduces horizon control, seismic control, logging control and facies control methods through the application of the least squares fitting of logging curves, seismic inversion and facies-controlled techniques. Based on the microgeology and thin section analyses, the lithology, lithofacies and periods of the Permian igneous rocks are described in detail. The seismic inversion and facies-controlled techniques were used to find the distribution characteristics of the igneous rocks and the 3D velocity volume. The least squares fitting of the logging curves overcome the problem that the work area is short of density logging data. Through analysis of thin sections, the lithofacies can be classified into eruption air-fall subfacies, eruption pyroclastic flow subfacies and eruption facies. © 2013 Published by Elsevier B.V. on behalf of China University of Mining & Technology.
