Application of micro-seismic monitoring technology in fracturing and water injection development of horizontal wells with low permeability and thin layer

Abstract

With the development of unconventional oil and gas reservoirs, microseismic monitoring has been developed rapidly as the key technology of hydraulic fracturing design, implementation and evaluation of this type of oil and gas reservoir. A oil field test area as a low-porosity and low permeability reservoir, the micro-seismic monitoring data were collected and processed during the development of fracturing horizontal well fracturing. The spatial development characteristics of the length, width and azimuth of the artificial fracture zone are analyzed by the method of overlooking the projection, fracturing and front edge calculation of the microseismic event point, and the later stage water injection is instructed to provide technical support for the future design of the horizontal well encryption and adjustment scheme.
