Abstract
Disclosed is a calculation method for a mobile fluid saturation after reservoir fracturing based on netting analysis, including: performing a fracturing experiment and micro-computed tomography (CT) experiment designs before and after fracturing; dividing a pore development area and a dense area; comparing micro-CT scanning experimental images of the same reservoir core sample before and after fracturing, and dividing a fracture network formed after fracturing; analyzing the propagation of fracturing fractures by netting analysis; determining a porosity of fracturing reconstruction; further determining a mobile fluid saturation after fracturing; and combining with a logging curve to realize the continuous calculation of mobile fluid saturation after fracturing. According to the present disclosure, on the basis of micro-CT scanning data before and after fracturing, the mobile fluid saturation after fracturing is quantitatively calculated by netting analysis and logging curves to cause the evaluation of the mobile fluid saturation after fracturing to be more accurate.
