Abstract

The invention relates to an ultrasonic measured and controlled water distributing device which solves the difficult problems of complicated allocation operation, low efficiency, limited application and the like existing in the prior art. The ultrasonic measured and controlled water distributing device comprises a sleeve pipe, a centralizer, a water-plugging packer, an ultrasonic measured and adjusted water distributor, a ball seat, a screen pipe and a screwed plug and is technically characterized in that underground ultrasonic communication units which are connected with a measurement and adjustment control unit are arranged in the ultrasonic measured and adjusted water distributor in the sleeve pipe, the measurement and adjustment control unit is respectively connected with an ultrasonic flow sensor, a pressure sensor, a temperature sensor and a regulating water nozzle driven by a micromotor, and each underground ultrasonic communication unit is respectively communicated with a ground ultrasonic communication unit by adopting ultrasonic encoding to realize data information transmission between the underground and the ground ultrasonic communication units and automatically finish the regulation on the water injection quantity of each water injection layer. The ultrasonic measured and controlled water distributing device has reasonable structural design, accurate water distribution quantity, no influence from the increase of the water injection layers and widened application range, and realizes that the distributed water flow is directly measured through wireless control by utilizing an ultrasonic communication technology.

Description

technical field

[0001] The invention relates to a water distribution and monitoring device for layered water injection in oilfield water injection wells, in particular to an ultrasonic measurement and control water distribution device for realizing wireless control and monitoring layered water distribution of water injection wells based on ultrasonic communication technology, which is widely used in deep wells, super Layered water distribution and monitoring of water injection wells in deep wells and inclined wells. Background technique

[0002] At present, since layered water injection has the dual functions of oil displacement, water replacement and formation energy replenishment, it has been paid more and more attention by various oil fields. However, the technical problem faced by layered water injection in the oilfield is that it cannot effectively achieve the best distribution according to the production requirements and the geological characteristics of each water inj...
