Method And Apparatus For Determining Permeability Of Reservoir

An apparatus for determining the permeability of a reservoir, wherein the reservoir comprises at least two zones, each of the zones comprises annular regions centered on a well axis of a target well in the reservoir, and the annular regions are located outside the target well;

• the apparatus comprises:
• a logging data acquiring module, a zone permeability determining module, a weight value determining module and a reservoir permeability determining module;
• wherein,
• the logging data acquiring module is configured to acquire logging data corresponding to the at least two zones respectively;
• the zone permeability determining module is configured to determine the permeability of a specified zone in the at least two zones based on logging data corresponding to the specified zone, wherein the specified zone represents any one of the at least two zones;
• the weight value determining module is configured to set weight values corresponding to the at least two zones respectively;
• and
• the reservoir permeability determining module is configured to determine the permeability of the reservoir based on the weight values and the permeability respectively corresponding to the at least two zones.
