Abstract

The invention discloses a water injection well movable underground power generation device and method. The water injection well movable underground power generation device comprises an outer pipe andat least one group of power generator set, wherein the power generator set is positioned in an inner cavity of the outer pipe; a spring piece is arranged at the inner wall of the left side of the outer pipe; in an ordinary state, the power generator set is elastically extruded on the inner wall of the right side of the outer pipe by the spring piece; an upper guide body and a lower guide body arearranged at two ends of the power generator set; the upper guide body is provided with a right lower inclined surface; the lower guide body is provided with a left lower inclined surface; a radial upper guide body through hole is formed in the upper guide body; and a radial lower guide body through hole is formed in the lower guide body. An upper support rod and a lower support body with the radial direction facing to the inner cavity of the outer pipe are arranged on the outer pipe; the upper support rod is inserted into the upper guide body through hole; and the lower support rod is insertedinto the lower guide body through hole. A water separation plate is arranged at the left side surface of the power generator set. The long-period and stable electric power supplementation can be provided for an underground intelligent water injection tool.

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...
