Abstract
A device and method for evaluating fracture initiation and propagation, and a stress sensitivity of a propped fracture is provided. The device includes a core part, a confining pressure loading part, a fracturing fluid pumping part, a stress sensitivity testing part and a fracture monitoring part. The method evaluates fracture initiation and propagation, and a stress sensitivity of a propped fracture using the above device and is reliable and simple to operate and guides optimization of construction parameters of hydraulic fracturing, thus achieving improvement in productivity of an oil and gas well.
