Propagation path tracing of hydraulically created fractures based on microseismic monitoring

To evaluate the effect of hydraulic fracturing in a low-permeability reservoir, propagation path tracing method for hydraulically created fractures was established based on microseismic monitoring data. First, numerical simulation wave process, grid search, and error-weight coefficient combined to locate source. Then, moment tensor inversion used determine tensile angle source mechanism fractures. Next, as weight-index size mixed-source fracture with shear quantization model. Finally, spatial topological relationship between determined by comprehensively considering location radius fractures, realize These tracking results can be one bases evaluation effect.
