The present disclosure provides an impact simulation device and simulation method for characteristics of a rock chip bed in a large displacement well. The device comprises a wellbore system, a drilling fluid circulation system, a rock chip transportation system, a drill pipe control system, a data acquisition system, and a data processing system. The wellbore system is configured to simulate a horizontal annulus environment for rock chip transportation during drilling. The drilling fluid circulation system is configured to provide drilling fluid to the wellbore system and collect flow data of the drilling fluid. The rock chip transportation system is configured to simulate an output of rock chips in the horizontal annulus environment during drilling and recover the rock chips. The drill pipe control system is configured to implement drilling simulation in the wellbore system. The data acquisition system is configured to collect monitoring data during the drilling simulation and to transmit the monitoring data to the data processing system. The data processing system is configured to determine ECD correction parameters based on the monitoring data.
