| description | The invention discloses a fracturing effect evaluation method and device based on distributed acoustic sensing. The method comprises the following steps: acquiring original data; the original data is sound data acquired based on distributed acoustic sensing in a hydraulic fracturing process; obtaining first frequency division energy according to the original data; on the basis of the first frequency division energy and the first data, the liquid inlet amount and the supporting dosage of each fracturing section of the fracturing well are calculated so as to evaluate the fracturing effect of each fracturing section; the first data comprises wellhead pumping displacement and sand ratio data obtained from a fracturing curve. According to the method, data collected in the monitoring process through the distributed acoustic sensing DAS technology is utilized, the data are processed to quantitatively calculate the volume or mass of the fracturing fluid and the propping agent of each perforation cluster entering the |
