Embodiment 1

[0026] Such as figure 1 with figure 2 As shown, the present invention provides an integrated electromagnetic flowmeter intelligent dispenser, which includes an upper joint 1, a housing 2 and a lower joint 16 connected sequentially from top to bottom, and the pipe wall of the housing 2 Set as an annular cavity, the lower part of the casing 2 is provided with a water outlet 8, and the interior of the dispenser is arranged as a hollow channel along the axial direction, and the feature is that a central controller 4 is installed in the middle of the annular cavity of the casing 2 , the annular cavity above the central controller 4 is equipped with an electromagnetic flowmeter 11, the communication module 10 and the pin body 3 are installed in the annular cavity above the electromagnetic flowmeter 11, and the annular cavity at the lower part of the central controller 4 A flow regulating device and an internal pressure sensor 5 are installed in the cavity, and the central controll...

Embodiment 2

[0034] Such as figure 1 As shown, the flow regulating device is located in the lower part of the annular cavity, and includes a motor 12, a transmission coupling shaft 13, and a flow regulating plug 15 connected in sequence. The lower part of the flow regulating plug 15 is provided with a nozzle hole, and the water The mouth hole corresponds to the water outlet hole 8 outside the intelligent dispenser.

[0035] Water enters the intelligent dispenser from the oil pipe. When the nozzle hole corresponds to the water outlet hole 8 outside the intelligent dispenser, a water injection channel is formed. Water is injected into the bottom layer from the water injection channel. When the computer on the ground monitors that the flow rate is too large At this time, the data is automatically fed back to the central controller 4, thereby controlling the motor 12 to drive the transmission coupling shaft 13 to move up and down, and at the same time the transmission coupling shaft 13 moves u...

Embodiment 3

[0038] Such as Figure 4 As shown, the electromagnetic flowmeter 11 includes an outer cylinder body 17, and a hollow central tube 18 is arranged inside the outer cylinder body 17, and an induction electrode 19 is arranged radially on the side wall in the middle of the central tube 18.

[0039]When water enters the intelligent dispenser from the oil pipe, the electromagnetic flowmeter 11 located on the upper part of the intelligent dispenser measures the flow rate through the upper sensing electrode 19, the central controller 4 monitors the flow data, and transmits the data conversion through the communication module 10 to The real-time monitoring of traffic is realized on the computer.

Abstract

The invention relates to an intelligent injection allocation device of an integrated electromagnetic flowmeter. The intelligent injection allocation device comprises an upper connector, a housing and a lower connector which are sequentially connected from top to bottom, wherein a central controller is installed in the middle of an annulus cavity of the housing, the electromagnetic flowmeter is installed in the annulus cavity of the upper portion of the central controller, a communicating module and a pin body are installed in the annulus cavity of the upper portion of the electromagnetic flowmeter, a flow adjusting device and an inner pressure sensor are installed in the annulus cavity of the lower portion of the central controller, the central controller is electrically connected with the pin body, the communicating module, the electromagnetic flowmeter, the flow adjusting device and the inner pressure sensor, and the pin body and the communicating module are connected to a ground controller through cables. The intelligent injection allocation device transmits data and performs power supply through cables and can automatically adjust layered water injection amount, and the problems of low layered water injection pass percent, large manual operating amount and unachieved underground real-time monitoring are solved.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to an intelligent dispenser for an integrated electromagnetic flowmeter. Background technique [0002] Oilfield water injection development is the most economical and effective method of reservoir development. With the continuous development of digital and intelligent technologies, the oilfield development mode is gradually developing from mechanical manual operation to digital and intelligent, greatly improving the technical indicators and reservoir development. In the early stage, the stratified flow test and deployment of separate injection wells all adopt the mechanical downhole docking test adjustment method. The operation process requires manual ground operation, the downhole mechanical docking adjustment of test instruments, flow test adjustment, packer seal inspection and pressure drop test and other downhole operation processes. Both need continuous lifting ...
