Establishment of interpretation model for physical parameters of bedrock in Zone X
The lithology of the bedrock is very complex,with significant differences between the horizontal and vertical planes.Matrix pores,dissolution pores,and fractures are developed within the bedrock,and the response patterns of oil,gas,and water layers are com-plex,which poses a challenge for calculating the physical parameters of the bedrock.For the overview of the research area,conventional logging data,nuclear magnetic logging data,and imaging logging data were used to calculate the physical property parameters of the re-search area,and a physical property parameter interpretation model suitable for the research area was established.In the process of es-tablishing a porosity interpretation model,a porosity interpretation model was established based on conventional logging data and nuclear magnetic logging data.Nuclear magnetic logging data was used to calculate the total porosity and effective porosity,conventional logging data was used to calculate neutron,density,and acoustic porosity,and neutron and density porosity were used to calculate effective po-rosity using gas reservoir correction formulas.For the permeability interpretation model,nuclear magnetic logging data KSDR and KTIM formula were used to calculate,and RQI and FZI were used to quantitatively calculate permeability.The results show that using the gas layer correction formula to calculate porosity is more effective,and using RQI and FZI to calculate permeability yields better results.
