AI Technical Summary
Existing methods for identifying volcanic structures suffer from low accuracy, inaccurate lithofacies classification, and difficulty in predicting overall spatial distribution in ultra-deep exploration, especially in volcanic systems involving intermediate to acidic volcanic rocks, where lithofacies structures are complex and highly ambiguous.
By fusing multi-source data, including core, well logging, and seismic data, a multi-constraint system of lithology, lithofacies, well logging response, seismic response, and geological evolution is established. Combining rock structure, tectonic features, and eruption mode, volcanic rock lithofacies types are classified, and the identification and spatial prediction of volcanic structures are achieved through seismic attribute fusion processing.
It improves the accuracy of volcanic structure identification, reduces the ambiguity of lithofacies division, and realizes the accuracy of ultra-deep volcanic rock oil and gas reservoir exploration and well-free area prediction capability. It is suitable for deep to ultra-deep volcanic rock oil and gas exploration in complex tectonic settings.
