Embodiment Construction
[0058] The invention discloses a method for judging reservoir fluid types by using resistivity data. The steps are as follows:
[0059] A. Accurately calculate the shale content, rock composition and porosity of the reservoir through calibration logging of core data;
[0060] Core calibration logging is one of the logging processing technologies widely used in the logging field at present, and the existing core calibration logging technology can be used; but better, we have made a major breakthrough on the basis of the original technology, the specific method is as follows :
[0061] ① Calibration logging of core data to calculate shale content
[0062] Use the core data such as X-ray diffraction analysis results and electron microscope scanning analysis results to determine the clay type and clay properties, comprehensively analyze the logging data, give priority to the calculation of the logging curve, calculation method and processing parameters of the shale content, and u...
