  • Patent number: 12360283
    Abstract: Disclosed is a method of quantitatively evaluating structural disturbance characteristics of present in-situ geo-stress in deep shale gas reservoirs, including: measuring geomechanics key parameters of key wells in different tectonic zones within a study area; performing interpretations of single-well profile rock mechanics and continuity of the in-situ geo-stress in magnitude and direction; establishing a geological model; performing anisotropic sequential Gaussian stochastic simulation to obtain three-dimensional (3D) heterogeneous rock mechanics parameter field distribution; performing prediction of distribution of geo-stress states in the study area, and calculating a stress structural index and stress disturbance factor of the target layer and a rotation degree of a maximum horizontal principal stress; and performing quantitative evaluation on an in-situ geo-stress structural disturbance and mapping.

  • Publication number: 20250035813
    Abstract: Disclosed is an invasion correction method and system for resistivity logging. The method includes the steps of: analyzing mud filtrate invasion features based on an actual resistivity logging curve; determining an invasion mechanism, and performing forward modeling on a resistivity logging response; performing inversion by a random forest method to form a correction chart; and outputting a formation resistivity to finally form the invasion correction method and system for resistivity logging. In the present disclosure, double lateral correction under an invasion condition is accomplished, while a chart method and an inversion method are combined, ensuring the accuracy and operating rate of correction.

  • Publication number: 20210202042
    Abstract: An information classification processing method of a carbonate reservoir and an information data processing terminal. The method includes: determining rock types; determining reservoir types on the basis of different rock types; and in accordance with the determined reservoir and rock types, performing porosity and permeability intersection by utilizing measured data; fitting a curve to obtain a porosity-permeability relation formula; and calculating permeability by utilizing the formula. According to the present invention, complex carbonate reservoirs in the Middle East can be classified, and porosity-permeability relations are respectively established, thereby increasing interpretation accuracy of permeability. According to the present invention, the reservoir types and the rock types can be rapidly and systematically classified, and clear porosity-permeability relations are obtained, so that interpretation of the permeability in oil reservoir exploitation is more accurate.
