Abstract

The present invention provides a downhole intelligence control system and method with a low-frequency awakening function. The system comprises a radio frequency label, the radio frequency label signal is connected with a low-frequency awakening control system, the low-frequency awakening control system is connected with the input end of the downhole intelligence control system, and the low-frequency awakening control system and the downhole intelligence control system are powered up by a power management unit. The downhole intelligence control system and method with the low-frequency awakening function are configured to arrange the low-frequency awakening control system at the front end of the downhole electronic measurement control system and control the work and the dormancy of the downhole electronic measurement control system by using the low-frequency awakening control system through a radio frequency chip so as to reduce the power consumption in the non-work state, improve the storage rate of the effective data and have an important value for prolonging downhole work time and improve the use ratio of the storage space.

Description

technical field [0001] The invention belongs to the field of oil and natural gas drilling, and in particular relates to a downhole intelligent control system with a low-frequency wake-up function and a control method thereof. Background technique [0002] In oil drilling tools, the downhole electronic measurement control unit is responsible for signal measurement of tool pose, downhole environmental information, and formation information, and makes analysis and decisions based on the measurement results to control oil drilling tools to perform corresponding actions. There are usually two power supply methods for the downhole measurement control unit. The turbine generator is used for power supply, which can obtain high-power stable DC power, but this power supply method has a complex structure and is limited to the stage of measurement while drilling. During the process, the electronic measurement control unit needs to monitor the downhole pressure and temperature informatio...
