ABSTRACT: The western part of north
Tarim Uplift underwent multi-stage tectonic movement and multiple stages of
magmatism. Igneous rocks are associated with carbonate and buried deep. The seismic response characteristics of igneous rocks are similar in many
respects to the seismic response characteristics of karst, making the
identification and prediction of igneous rocks more difficult. This study compares the seismic reflection characteristics of igneous rocks.
Set up three types of igneous rock seismic facies model penetration type,
fracture type and central type. And it concluded that
a time-slice, coherence analysis, analysis of the seismic properties of the
layers and the method of three-dimensional engraving to identify the igneous
rocks. This method has been applied to the identification and prediction of
carbonate rock buried and hill igneous rocks in
the north Tarim basin YingMaiLi region and has achieved good results.
