The Research On The Well Log Interpretation Methods Of The Volcanics Reservoir In YSX,YSY Well Fields Of Yingcheng Formation

Research on Volcano rocks in geology already has been a long history,volcanic rock research in China started late but development is rapid.In recent years,as the development of the volcanics reservoir exploration,volcanic rock reservoir of oil and gas exploration has become a new field.This paper first summarize the regional profiles.According to the lithology,logging and seismic data,divide the formation of the Yingcheng into three sections;Carry out" four properties relation " study base on the core of microscopic identification,with referencing debris,logging data,combined with conventional logging curve features and oil testing,material analysis data.Under the guidance of in the" properties" relation,identify lithology,interpret parameter,recognize fluid property.According to different lithology have different logging curve characteristics to summarize the law,at the same time,with imaging well logging technology to assist,in addition,to find out the best sensitive curve to make crossplot to distinguish sedimentary rocks and volcano lithology,and different volcano rocks lithology,recognize lithology with comprehensive use of above methods.Then interprete the reservoir parameters:shale content,porosity,permeability,saturation.Establish logging parameter interpretation model.According to the test data analysis for reservoir fluid property and reservoir fluid distribution,in summing up conventional logging curve controlled by the fluid properties influence,on the basis of which derived a lot of fluid property identification methods.Establish interpretation model which suit for the regional characteristics.Interpretate the gas and water layer,determining gas water interface.Rich domestic volcano rock reservoir research theory for the volcano rock reservoir logging interpretation.
