Title:
METHOD FOR CALCULATING PORE DISTRIBUTION OF MARINE SEDIMENT LAYER
Document Type and Number:
WIPO Patent Application WO/2021/129315
Kind Code:
A1
Abstract:
Provided is a method for calculating the pore distribution of a marine sediment layer. The method comprises: S1, acquiring columnar marine sediment layer drilled cores at different positions in a target region, and with regard to each columnar marine sediment layer drilled core, preparing a plurality of samples at certain intervals in the axial direction; S2, measuring the surface area of the samples; S3, constructing a sediment sample pore size calculation model; and S4, calculating an average pore diameter of each sample by using the sediment sample pore size calculation model to obtain the pore distribution of a marine sediment layer. According to the method, the pore distribution of a marine sediment layer is easily, conveniently and effectively calculated, and the method can be applied to the analysis of submarine stability, the analysis of marine engineering safety, the prediction of submarine landslide and tsunami occurrence, the prediction of submarine fluid channels, and the prediction of the accumulation and reservoir formation of new-type mineral resources such as natural gas hydrates.
