Abstract
The embodiments of the present disclosure provide a method for diagnosing control effectiveness of a fracture height in hydraulic fracturing by combining monitoring a pressure signal, comprising: obtaining engineering data and geological data; calculating a fracture slit fluid pressure, a double-logarithmic slope of the fracture slit fluid pressure, and a bedding fracture pressure; updating a growth time of the fracture height and a reference pressure based on the fracture height in hydraulic fracturing; based on determining whether a fracturing construction operation ends, updating the cumulative fracturing time or calculating a ratio of the growth time of the fracture height to the total time of hydraulic fracturing.
