Abstract: A gimbal system includes a gimbal configured to support a load and including one or more motors configured to change an attitude of the load, one or more processors, and a memory coupled to the one or more processors and storing instructions that, when executed by the one or more processors, cause the system to obtain a target control parameter of the one or more motors, and, in response to the gimbal switching from a power-on state to a powered-off state or a sleep state, control, according to the target control parameter, a torque of at least one of the one or more motors to decrease at a first speed within a first time period and to decrease at a second speed within a second time period after the first time period. The second speed is lower than the first speed.

Abstract: An intelligent identification method of aquifer distribution in complex edge-water oil and gas reservoirs is provided. The problem, that targeted water control countermeasures cannot be proposed due to unclear identification of edge-water distribution in complex edge-water reservoirs, is resolved. Based on geological data and production data of a single well, establish a numerical simulation model of a water influx unit for simulating inflow dynamic of complex edge-water influx; by a genetic algorithm, correct characteristic parameters of an aquifer unit, including volume and water influx of the aquifer unit; automatically fit dynamic production data calculated by the model with actual dynamic production data, to obtain optimal characteristic parameters of the aquifer unit; and assign the characteristic parameters to the aquifer unit for inversion to determine aquifer distribution.

Abstract: The present disclosure relates to a prediction method for constant production decline of a water-producing gas well in a highly heterogeneous reservoir.
