Abstract

AbstractThe fracturing microseismic monitoring technology has been widely used in major oil fields in China, and it is of great significance in the evaluation of conventional and unconventional oil and gas reservoirs, especially in the evaluation of the gas injection situation of underground gas storage and the long-term performance of the oil reservoir. Combining the characteristics of oil and gas in conventional and unconventional reservoirs, the perforation method and fracturing scale of oil and gas wells, this article focuses on the comparison of different response of microseismic monitoring results in tight sandstone, shale, coal and carbonate rocks, through the regional microseismic monitoring results to plan the overall development well pattern, guide the selection of the direction of the drilling well trajectory, prepare the reservoir reconstruction plan and verify regional geostress direction.KeywordsMicroseismic monitoringReservoir reconstructionFracture network evaluation
