Abstract
A three-dimensional characterization method of a hydrocarbon secondary migration channel includes: step 1, collecting lithofacies seismic inversion data of a research area, and constructing a three-dimensional geological model including mudstone and sandstone; step 2, performing lithofacies attribute determination and updating on planar mudstone data; step 3, performing lithofacies attribute determination and updating on sectional mudstone data; step 4, adding fault data and updating lithofacies attributes according to an intersection relationship between a sand body distribution area and the fault to obtain a model intersecting with the fault and a model without intersecting with the fault; step 5, performing a zigzag connectivity judgment on a sand body distribution area to obtain a judgment result, and updating lithofacies attributes according to the judgment result; step 6, obtaining a target three-dimensional geological model; and step 7, determining the hydrocarbon secondary migration channel.
