摘要

The</span><span style="font-family:""> </span><span style="font-family:Verdana;">western part of north Tarim Uplift underwent multi-stage tectonic movement and multiple stages of magmatism.</span><span style="font-family:""> </span><span style="font-family:Verdana;">Igneous rocks are associated with carbonate and buried deep.</span><span style="font-family:""> </span><span style="font-family:Verdana;">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.</span><span style="font-family:""> </span><span style="font-family:Verdana;">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</span><span style="font-family:Verdana;">. </span><span style="font-family:Verdana;">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 </span><span style="font-family:Verdana;">and </span><span style="font-family:Verdana;">hill igneous rocks in the north Tarim basin YingMaiLi region and has achieved good results.
