The present invention provides a method and device for determining geological parameters of shale gas reservoirs. By adopting different grid areas and performing grid processing on scanning electron microscope images of shale gas reservoirs that have undergone digital image preprocessing, it is determined to meet the requirements of In each grid of the image, the difference between the mineral content ratios of shale gas reservoirs is less than the minimum grid area Sa under the condition of the first preset threshold, so the minimum grid area Sa is regarded as the shale gas reservoir The area of the characterization unit of the layer, because the scanning electron microscope image of the digitized image of the shale gas reservoir is analyzed on the micro-nano scale, so as to determine the geological parameters of the shale gas reservoir, which improves the quality of the shale gas reservoir. The calculation accuracy of geological parameters solves the technical problem of inaccurate geological parameters of shale gas reservoirs determined in the prior art.
Description
technical field [0001] The invention relates to natural gas exploration technology, in particular to a method and device for determining geological parameters of shale gas reservoirs. Background technique [0002] Shale gas reservoirs are the main enrichment places of shale gas. The geological parameters of shale gas reservoirs have important geological significance for the exploration and development of shale gas. Therefore, it is necessary to determine the geological parameters of shale gas reservoirs. [0003] In the prior art, the geological parameters of shale gas reservoirs are qualitatively described, which often leads to inaccurate geological parameters of shale gas reservoirs. That is to say, in the prior art, there is a lack of methods for quantitatively determining geological parameters of shale gas reservoirs. Contents of the invention [0004] The invention provides a method and device for determining geological parameters of shale gas reservoirs, which are u...
