Research On Comprehensive Explanation Model Of Logging And Well Test And Its Application

With the development of oilfield development technology, it bccomes more and moreimportant to improve the accuracy of reservoir permeability characteirstics. This article studiedthe method of solving the permeability from two direction, logging and well test. First of all，author deeply researched a logging interpretation model which is used for reservoir parameters,and solved porosity, permeability and the saturation with different logging interpretationmethods; Second, in terms of the well test, the relationship between the typical lfow pattern ofthe linear flow, dual linear flow, spherical lfow and the permeability of reservoir wereanalyzed, while analysis of the basic interpretation of the reservoir models, from theperspective of well test analysis of a variety of methods to solve the reservoir permeability*and then judged the reservoir permeability more accurate.Finally, the paper solve the remaining oil saturation of reservoirs and penetration basedon combing logging, well testing and make the establishment of the mutual relations ofsaturation, the water production rate and permeability, make the use of log data and well testdata to solve the reservoir permeability, the paper use Logging methods to measure eachproducing formation permeability, the linear regression method to calculate the waterproduction rate of each production layer, ifnally, use the relationship built in the paper toCalculate every apparent penetration rate under well testing and logging comprehensivecondition Instance of the argument, combined with logging data and well test data obtained foreach production layer penetration is more in line with the actual situation of the reservoir，canbe more accurate understanding of the permeability characteirstics of the reservoir.
