The Technology Research on Volcanite Lithology Log Identification Method

This paper researches the response characteristics of the volcanic rock reservoir,The diagnostic physical quantity lithology was recognized.Conventional logging cross-plotting recognition method,imaging logging cross-plotting recognition method were mainly adopted.By taking L well as an example,conventional logging and FMI were used to discriminate the lithology.According to the relative research and genetic relationship between different lithology association and facies,the igneous lithofacies of singlewell is defined and the control action of different subfacies' parts to physical property is also researched.The field practice demonstrates that the application result of this method is very good in the research of igneous reservoir,and this method can be taken as references for the research on reser-voirs of similar type.
