Non-contact turbine drive self-power-generating intelligent water distributor

Abstract

The invention provides a non-contact turbine drive self-power-generating intelligent water distributor. The non-contact turbine drive self-power-generating intelligent water distributor comprises an internal pressure meter, a turbine power generating device and a magnetic coupling packer. The internal pressure meter can measure the internal water pressure and monitor pressure waves in a pipeline,and information transmission between the ground and the water distributor is achieved. The turbine power generating device pushes an impeller to rotate through water currents, thus, a power generatoris driven to rotate to achieve power generation, and meanwhile the flow of water flowing through the turbine power generating device is measured. The numerical control packer is under magnetic coupling drive, trigger of a high-torque direct current motor can be converted into soft start, movable sealing is converted into fixed sealing, and the numerical control packer is used for adjusting the size of a flow outlet. By means of the water distributor, the problem about power supply in the existing water distribution process is solved, and information transmission between the ground and the down-hole space is achieved. The whole water distributor can be directly put in the down-hole space, it is not needed to put other tools in the down-hole space for measuring and adjusting, and the water injection process is greatly simplified.

Description

technical field [0001] The invention relates to a water distributor used in the field of oilfield water injection production. Background technique [0002] In oil fields, oil reservoirs are distributed by layers, and the water absorption effect of each layer is very different. Only layered water injection can solve the problem of unbalanced water injection in each layer. The layered water injection technology has entered the era of intelligent measurement and adjustment. The intelligent layered water injection technology with "bridge eccentricity + steel pipe cable direct reading measurement and adjustment" as the main body has been widely promoted and applied in oil field water injection, greatly improving the injection efficiency. The efficiency of water well measurement and adjustment shortens the time of measurement and adjustment. However, there are still many problems in the current layered water injection technology, such as the shortening of the measurement and adju...
