Abstract

The embodiment of the invention discloses a micro-seismic signal reconstruction method and system utilizing conversion sparsity. The method comprises the steps of 101, acquiring a signal sequence S acquired according to a time sequence; 102, solving a signal comparison sequence; 103, solving the total number of sequence segments; 104, solving a signal segmentation sequence; 105, solving a controlfactor; 106, solving a conversion sparse matrix; and 107, solving a reconstructed signal sequence.

Description

technical field [0001] The invention relates to the field of geosciences, in particular to a microseismic signal reconstruction method and system. Background technique [0002] Hydraulic fracturing microseismic monitoring technology is an important new technology developed in the fields of low permeability reservoir fracturing, reservoir driving and water flooding front in recent years, and it is also an important supporting technology for shale gas development. This technology arranges a multi-level three-component geophone arrangement in adjacent wells to monitor the microseismic events generated in the hydraulic fracturing process of the target interval of the fracturing well, and inverts the microseismic events to obtain parameters such as the source position, so as to describe the hydraulic fracturing The geometry and spatial distribution of fracture growth during the process provide real-time information on the length, height, width and orientation of fractures produce...
