Method for Identifying Igneous Lithological Logging in the West of Northern Tarim Basin

Study on igneous rocks in Tarim Oilfield was started later, based on the data of coring and logging, igneous rocks in west North Tarim Basin were divided and arranged, and the log responses of the corresponding types were investigated.By analyzing correlation between lithologic types and their responses, a lithologic identification model was established by using some crossplots, it was used to identify lithology of igneous rocks in coring wells in the study area based on the Program of FORWARD.This method may play an important role in non-coring wells, and provide a good foundation for igneous reservoir evaluation in the studied area.
