摘要： Techniques for evaluating a fluid flow through a wellbore include identifying an input characterizing a fluid flow through a wellbore; identifying an input characterizing a geometry of the wellbore; generating a model of the wellbore based on the inputs characterizing the fluid flow and the geometry of the wellbore; simulating the fluid flow through the wellbore based on evaluating the model with a numerical method that determines fluid flow conditions at a first boundary location uphole and adjacent to a perforation of a plurality of perforations in the wellbore and at a second boundary location downhole and adjacent to the perforation; and preparing, based on the fluid flow conditions determined with the numerical method, an output associated with the simulated fluid flow through the wellbore for display to a user.

摘要： Systems, methods, and software can be used to simulate a fracture treatment. In some aspects, physically separate rock blocks of a subterranean zone are modeled by separate block models. The block model for each physically separate rock block represents intra-block mechanics of the rock block, for example, as a group of discrete block elements. Interactions between adjacent pairs of the rock blocks are modeled by separate joint models. The joint model for each adjacent pair of rock blocks represents inter-block mechanics between the adjacent rock blocks, for example, as pre-defined joints. The block models and joint models are used to simulate an injection treatment of the subterranean zone.

摘要： Systems, methods, and software can be used to simulate a fracture treatment. In some aspects, a common solution vector for multiple distinct subsystem models is defined. Each subsystem model represents a distinct subsystem of an injection treatment system. Parameters of the subsystem models are updated based on the solution vector according to predefined relationships between the solution vector and the parameters of the subsystem models. The subsystem models are operated based on the solution vector and the updated parameters.
