A new prediction method for high-permeability carbonate reservoir based on multi-source data fusion and its application
Accurate prediction of high-permeability carbonate reservoirs is crucial for enhancing efficiency and recovery rates in oil and gas field development. The paper proposes a method integrating multi-source data to address the challenge of predicting high-permeability zones in carbonate reservoirs
especially the urgent need for characterizing high-permeability reservoirs in waterflooded oilfields in the Middle East. This method can accurately identify high-permeability zones based on the combination of core and thin section observations with petrophysical tests. Subsequently
intelligent logging lithofacies analysis techniques are employed to achieve the refined classification of rock types
and establish a reliable porosity-permeability relationship model. To overcome the precision limitations of conventional methods
a high-resolution full-frequency seismic inversion technology is used to delineate reservoir properties. Combined with deep learning-based approaches
an achievement has been made in the intelligent prediction of three-dimensional spatial permeability distribution. By integrating seismic-based minor fault prediction with dynamic production data
the study reveals the controlling regularity of fracture system on permeability distribution
thus achieving dynamic calibration and optimization of predictions. In practical applications in W field of the Middle East
this method reduces permeability prediction errors from traditional levels of 15 % to below 7 %
providing a reliable basis for well network optimization and injection-production scheme adjustment
thereby enhancing the development effect. This predictive framework offers an innovative solution for efficiently exploiting complex carbonate reservoirs
with promising application prospects and significant potential for widespread adoption.
