    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.

    Abstract: Methods and systems are disclosed. The methods may include collecting matrix training data along a first depth interval of a first well and training a first artificial intelligence (AI) model using the matrix training data. The methods may further include collecting well data along a depth interval of a well, inputting the well data into the first AI model, and producing a predicted matrix permeability log along the depth interval from the first AI model. The methods may still further include collecting an image at a discrete depth within the depth interval of the well, where the image is of a fracture, inputting the image into a second AI model, producing a predicted fracture permeability from the second AI model, and generating the predicted hybrid-permeability log using the predicted matrix permeability log and the predicted fracture permeability.

    Abstract: The present invention discloses a hydraulic fracturing system for driving a plunger pump with a turbine engine, including a fracturing equipment comprising a turbine engine fueled by natural gas or diesel as a power source, an exhaust system, and a plunger pump; a high-low pressure manifold; a blending equipment adapted to blend a fracturing base fluid; and a sand-mixing equipment adapted to provide the fracturing base fluid and a fracturing proppant to the high-low pressure manifold. A first end of the high-low pressure manifold is connected to the fracturing equipment through a connection pipeline. A second end of the high-low pressure manifold is connected to a wellhead. An exhaust end of the turbine engine is connected to the exhaust system whereas an output driving end of the turbine engine is connected to the plunger pump via a connection device. The connection device comprises at least a reduction gearbox. An input speed of the reduction gearbox matches an output driving speed of the turbine engine, and an input torque of the reduction gearbox matches an output driving torque of the turbine engine.
