A kind of downhole intelligent water distributor

Abstract

The invention relates to the water distributor technology, which is used to solve the problem that the water injection pipeline is difficult to align with the packer when the water injection pipeline goes deep into the water injection well; The problem that the damage of the communication cable affects the stability of the electronic control system is specifically an underground intelligent water distributor, including a water injection well, a packer, a water distributor and a water injection pipeline; the invention follows the water distributor through a support ring to move inside the water injection well , so that the water injection pipe is aligned with the middle position of the packer under the support of the four rollers on the support ring, and the end of the water injection pipe that penetrates into the water injection well can be driven deep into the water injection well by the rotation of the drag plate Inside, the power generation equipment is driven by the rotation of the drag plate to generate power, so that the water distributor at the corresponding position can be supplied with power by the power generated by the internal equipment of the power generation box, and is less affected by the power supply transmitted by the communication cable.

Description

technical field [0001] The invention relates to a water distributor technology, in particular to an underground intelligent water distributor. Background technique [0002] A water distributor is a special downhole tool used for quantitative water injection of each oil layer during layered water injection. It is mainly composed of a water distribution body, a water distribution nozzle, a water nozzle body, a gland and a sealing ring; in the prior art, the water injection device connected to the water distributor After the pipeline enters the water injection well, it needs to pass through multiple packers to the bottom of the water injection well. During the movement of the water injection pipeline inside the water injection well, one end of the water injection pipeline needs to be aligned with the middle of the packer. , to prevent the water injection pipeline from being blocked and difficult to pass through the packer to the bottom of the water injection well. During the pr...

Problems solved by technology

[0003] The purpose of the present invention is to set the support ring on the outer wall of the water distributor, and follow the water distributor to move inside the water injection well. The four rollers on the support ring are supported on the inner wall of the water injection well, which is convenient for the water injection pipeline and isolation. The alignment at the middle position of the device is rotated under the traction of external equipment through the elliptical dragging plate, so that one end of the water injection pipe that penetrates into the interior of the water injection well can be driven deep into the interior of the water injection well by the support ring, and the elliptical dragging plate is used in the outside world Under the traction of the equipment, it rotates and drives the power generation equipment inside the power generation box to generate electricity, so that the water distributor at the corresponding position can be supplied with power by the power generated by the equipment inside the power generation box, which is less affected by the power supply transmitted by the communication cable, and solves the problem of deep water injection During the injection well process, the water injection pipeline is difficult to align with the packer, it is difficult to push the water injection pipeline deep after the water injection pipeline penetrates into the water injection well, and the damage of the communication cable during the penetration of the water injection pipeline affects the stability of the electronic control system. And propose a kind of downhole intelligent water distributor
