Abstract

The invention discloses a movable downhole power generation device and method for a water injection well, wherein the device includes an outer tube and a generator set, the generator set is located in the inner cavity of the outer tube, and a spring plate is installed on the inner wall of the left side of the outer tube. The spring leaf elastically squeezes the generator set against the inner wall on the right side of the outer tube. The generator set includes at least one set, and the two ends of the generator set are an upper guide body and a lower guide body respectively. The upper guide body is provided with a right lower slope, and the lower guide body is provided with a left lower slope. The upper guide body is provided with a radial upper guide body through hole, and the lower guide body is provided with a radial lower guide body through hole. The outer tube is provided with an upper support rod and a lower support rod radially facing the inner cavity of the outer tube, wherein the upper support rod is inserted into the through hole of the upper guide body, and the lower support rod is inserted into the through hole of the lower guide body. A water baffle is arranged on the left side of the generator set. The invention can provide long-term and stable power supplement for downhole intelligent water injection tools.

Description

technical field [0001] The invention relates to the technical field of oilfield water injection development, in particular to a movable 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 trip of measuring...
