Description

technical field [0001] The invention relates to a power generation test device, in particular to a downhole pressure difference power generation test device. Background technique [0002] Well reservoir management and well production optimization rely on real-time reservoir data from sensors and monitoring systems that monitor various production parameters, including temperature, pressure, flow rate, and water cut of fluids. In smart wells, sensors are used in conjunction with flow control devices to adjust production flow and optimize overall well performance. [0003] Currently, most of the small devices used to monitor underground crude oil production are powered by disposable or rechargeable batteries. These traditional chemical batteries cannot meet the needs of the system due to their large mass and volume, limited energy supply, and possible environmental pollution. In addition, the depth of the oil well is very large, which will cause a lot of inconvenience when ch...
