Abstract

The invention discloses a throwing-and-fishing type downhole power generation device and method for water injection wells, wherein the device includes a hollow positioning sub-joint and a throwing-and-fishing type generator set, the throwing-and-fishing type generator set is arranged in the inner cavity of the hollow positioning sub-joint, and the hollow The inner wall of the positioning nipple is provided with a nipple positive joint and a nipple negative joint. The lower end of the throwing type generator set is connected to the positioning joint. The outer wall of the positioning joint is positioned on the positioning step set on the inner wall of the hollow positioning joint. The positioning joint Set up the positioning wet positive terminal and the positioning wet negative terminal. The positioning wet positive terminal and the positioning wet negative terminal are connected with the positive and negative terminals of the throwing and fishing generator set on the one hand, and on the other hand with the short joint positive joint and short joint negative joint. corresponding connection. The invention can provide long-term and stable power energy for downhole intelligent water injection tools. The long-term normal operation of the downhole intelligent water injection device is guaranteed.

Description

technical field [0001] The invention relates to the technical field of oilfield water injection development, in particular to a throwing and fishing type downhole power generation device and method for water injection wells. Background technique [0002] In the field of oilfield water injection development, layered water injection has become the main means to improve the effect of water injection development. The development of layered water injection technology has gone through four stages. The first stage is fixed layered water injection technology. The nozzle is fixed and the water injection volume cannot be adjusted. ; The second stage is the movable layered water injection technology, and the movable water nozzle can be tested and deployed by throwing the water nozzle multiple times; the third stage is the integrated layered water injection technology of measurement and adjustment, the water nozzle is built in the water distribution In the device, it only needs to run a...
