Abstract

The invention discloses a water injection well ball throwing type downhole power generation device and method. The device comprises a main cavity, and a generator set; a water injection channel and aneccentric type electric generator cavity are arranged in the main cavity, the generator set is located in the eccentric type electric generator cavity, the upper end of the eccentric type electric generator cavity communicates with the position above an upper port of the water injection channel of the main cavity through an independent channel, the position, close to the bottom, of the eccentrictype electric generator cavity is provided with a radial water outlet hole communicating with the water injection channel, the upper end of the main cavity is connected with an upper joint, the upperjoint is provided with a main channel and a side flowing channel, the main channel communicates with the water injection channel in the main cavity, below the main channel, a ball base capable of bearing soluble balls is arranged in the main channel, and the independent channel in the upper end of the eccentric type electric generator cavity is the side flowing channel. Long-term stable power supplementing can be provided for the downhole intelligent water injection tool.

Description

technical field [0001] The invention relates to the technical field of oilfield water injection development, in particular to a ball-throwing 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 mea...
