Title:
FINE GRAIN SEDIMENTARY ROCK LAYER STRUCTURE CHARACTERISATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/192625
Kind Code:
A1
Abstract:
The present application relates to a fine grain sedimentary rock layer structure characterisation method, comprising: S1, performing image pre-processing; S2, loading an image, and normalising to a specified size; S3, performing mean filtering, an expansion operation and binarisation processing on the image; S4, determining whether layers have developed; S5, determining the numbers of bright layers and dark layers; S6, determining the degree of continuity of the bright and dark layers; S7, according to statistical and calculation results, writing characterisation parameters into Excel. The present application can accurately determine structural characteristics which characterise fine grain sedimentary rock layers, and the effect is better than the prior art, so as to satisfy requirements for systematically depicting fine grain sedimentary rock layer development characteristics, and to provide technical support for shale oil and gas exploration and development.
