Abstract
A storage-type downhole electronic pressure gauge requires long-time recording of downhole pressure and temperature data during fracturing. Battery life is a vital performance index of this type of pressure gauge. Given inherent limitations in battery capacity, reducing power consumption is the main method to promote a reliable pressure gauge electronic system and extend battery life. A low-voltage power supply, low-power peripheral devices, and a dual power module are used to improve the hardware system. Moreover, the dynamic management of power consumption in multiple operating modes and the dynamic adjustment of the operating frequency of the controller are used to improve the software system. In this way, the power consumption of a pressure gauge electronic system can be considerably decreased. System reliability and stability are also promoted, and the test cost is decreased. Downhole testing of the pressure gauge examined in this study shows that the current consumption of the proposed system is decreased by 69%, and the battery life is extended to more than 3.2 times.
