Embodiment Construction

[0008] The present invention will be further described in detail through specific embodiments below, but these embodiments are only for illustration and do not limit the scope of the present invention.

[0009] The present invention proposes an underground relay power supply device, which is characterized in that the relay power supply device first supplies ground high-voltage DC power to the underground repeater, and then converts it into a low-voltage DC power supply for use by the intelligent dispenser through the repeater .

[0010] The downhole repeater includes: central channel, tubing collar (1), cable joint (2), circuit board (3), connecting outer tube (4), tubing adapter (5), lower joint (6), center seal Pipe (7), power module (8), mounting bracket (9), upper joint (10).

[0011] The downhole repeater is installed above the uppermost intelligent dispenser. It is a bridge between the ground control system and the downhole intelligent dispenser. It not only performs da...

Abstract

The invention provides a downhole repeater power supplying device. The downhole repeater power supplying device is characterized in that firstly, the repeater power supplying device supplies a groundhigh-voltage direct-current power supply to a downhole repeater, then the ground high-voltage direct-current power supply is converted into a low-voltage direct-current power supply by the repeater tobe used by intelligent injection allocation devices, the downhole repeater is mounted on the upper part of the intelligent injection allocation device on the uppermost layer, the downhole repeater isconnected with a ground control system and the intelligent injection allocation devices, and the ground high-voltage direct-current power supply is firstly supplied to the downhole repeater and thenis converted into the low-voltage direct-current power supply by the repeater to be used by intelligent injection allocation devices. According to the downhole repeater power supplying device, the ground high-voltage direct-current power supply is firstly supplied to the downhole repeater and then converted into the low-voltage direct-current power supply by the repeater to be used by intelligentinjection allocation devices, and thus the long-term working reliability of an intelligent injection allocation device system is improved.

Description

technical field [0001] The invention belongs to the technical field of downhole instrument structures, and in particular relates to an downhole relay power supply device and method. Background technique [0002] After the oil field is exploited in the middle and later stages, the method of water injection or polymer flooding into the formation is generally used to ensure the crude oil production. The injection well layered measurement and adjustment technology has been promoted and implemented in oilfields for many years, and has played a significant role in improving the economic benefits of oilfields. Water injection wells are generally divided into multiple layers, and precise control of water injection in each layer is the key to ensuring output. [0003] At present, the oil field mainly uses a direct-reading seal inspection device to run into the well to check the seal of each layer, and a direct-reading water volume adjustment device to run into the well to adjust the...
