Embodiment 1

[0026] Such as figure 1 and figure 2 As shown, the present invention provides a wheel injection intelligent dispenser, including a dispenser connected in series on the oil pipe, an adjustment cavity 3 is set on the outer side of the center pipe 4 in the dispenser, and the lower part of the adjustment cavity 3 is provided with an opening , the opening is equipped with a regulating valve 12, and it is characterized in that: a control module for controlling the opening and closing of the regulating valve 12 is also installed in the housing of the dispenser, and the control module is also electrically connected with the ground controller 13, and the control module It also includes at least one reader capable of identifying electronic tags.

[0027] Such as figure 1 As shown, the control module includes an electrically connected electric control unit C1, a power supply unit C2, a drive unit C3, a switch control unit C4 and a monitoring unit C5, and the electric control unit C1, ...

Embodiment 2

[0033] On the basis of Example 1, such as figure 2 As shown, the interior of the dispenser is a hollow water injection channel, and water is injected into the water injection channel of the dispenser from the oil pipe. The opening of the lower part is injected into each stratum, and the outside of the dispenser includes an upper joint body 11, a connecting body 5, a central pipe 4, and a lower joint body 1, which are sequentially connected from top to bottom. Shell one 9, shell two 7, shell three 6 are arranged.

[0034] The electric control unit C1 and the power supply unit C2 are arranged in the housing one 9, and the electric control unit C1 and the power supply unit C2 are connected by a connecting piece 8, which is used as a transition connection to facilitate the arrangement of the circuits of each unit. .

[0035] The driving unit C3 is set in the second casing 7 , the switch control unit C4 is set in the third casing 6 , and the monitoring unit C5 is set in the adju...

Embodiment 3

[0037] On the basis of Example 2, such as figure 2 As shown, further, in order to seal the shell one 9, the upper end of the shell one 9 is provided with an upper end cap 10 . In order to seal the adjustment cavity 3 , a lower end cap 2 is provided at the lower end of the adjustment cavity 3 .

[0038] The lower end cap 2 and the adjustment cavity 3, the adjustment cavity 3 and the upper layer of the connecting body 5, the connecting body 5 and the shell three 6, the shell three 6 and the shell two 7, the shell two 7 and the transition piece 8, the transition Part 8 and shell one 9, shell one 9 and upper end cap 10, upper end cap 10 and upper joint body 11 are all connected by plugging.

[0039] The lower end cap 2 and the adjustment cavity 3, the adjustment cavity 3 and the connecting body 5, the connecting body 5 and the shell three 6, the shell three 6 and the shell two 7, the shell two 7 and the transition piece 8, the transition piece 8 and shell one 9, between shell o...

Abstract

The application relates to ring irrigate intelligent fitting injection device, including serial joining oil pipe fitting injection device, inside of which central tube outer circle covers adjusting chamber, under which opens an entrance, on which installs a adjusting jam, injection device shell inside installs control modular for monitoring adjusting jam switch-on-and-off, who yet joins ground control, control modular still at least includes a reader for electronic label identification; said injection device self carries out action according to preset ring irrigate circuit period, achieves self replacement of infusion layer alternate infusing water, besides achieving automatic switching function, yet carries temperature, pressure, adjusting electric current, electric pressure and more parameter monitor and storing function, injection device reaches 3 years or above effective service life, seal check period and ring irrigate period of injection device adjusts according to different fitting injection requirement, satisfies different irrigate well fitting injection requirement.

Description

technical field [0001] The invention relates to the technical field of oil exploitation, in particular to an intelligent injector for wheel injection. Background technique [0002] With the deepening of oilfield development, the number of separate injection wells has increased year by year, the workload of measurement and adjustment is heavy, and the cost of supporting measurement and adjustment has increased year by year; the frequent occurrence of obstructions in measurement and adjustment has resulted in high costs for later detection of strings and pressure operations; pressure fluctuations, formation Influenced by factors such as changes in water absorption capacity, the inspection and matching qualification rate dropped rapidly, and it was difficult to meet the needs of fine layered water injection in oilfields. At the same time, in order to further improve the digital level of water injection and explore new ways of layered water injection, research and experiments on ...
