Abstract
The utility model discloses a there is not eccentric water injection device of butt joint. Including being located eccentric injection mandrel in the pit, be equipped with intelligent blanking plug in the eccentric orfice of eccentric injection mandrel, be equipped with the water injection hole on the pore wall of eccentric orfice, inside micro motor, battery, control circuit and the signal receiver of being equipped with of intelligence blanking plug, signal receiver is through the ultrasonic wave and establish the signal emission device wireless connection on the quantity of water regulation device. The utility model discloses can reduce intensity of labour according to the automatic measure and regulate of setting parameters. Need not the butt joint, avoid not docking and cause the measure and regulate failure, do not have impact damage, improve the life of instrument.
Description
Technical field
This utility model relates to a kind of without docking eccentric water injection device, belongs to downhole instrument technical field.
Background technology
Oilfield exploitation is to after the later stage, and the general mode used to stratum water filling or polymer flooding ensures crude output.Water injection well typically divides eccentric well and concentric well, all has multiple layers of position, and controlling each layer water injection rate is an important process.Oil field bias well mainly uses direct read type water quantity regulating device to carry out water injection rate regulation at present, and survey timing enters measurement and adjustment instrument device and docks with DH eccentric center switch blanking plug under needing, stopper for regulating realizes flow-control.There is problems of docking operation and there is more influence factor, often result in and do not dock, success rate is low, and docking operation is also a hard impact process, easily causes conditioning instrumentation and blanking plug damages.
Utility model content
The purpose of this utility model is, it is provided that a kind of without docking eccentric water injection device.Realize dispensing well and efficiently survey tune.Solve docking problem, it is to avoid do not dock and impact failure.
The technical solution of the utility model:
A kind of without docking eccentric water injection device, including the eccentric injection mandrel being positioned at down-hole；It is provided with intelligent stopper in the eccentric orfice of eccentric injection mandrel；The hole wall of eccentric orfice is provided with water injection hole；Micromachine, battery, control circuit and signal receiving device it is provided with inside intelligent stopper；Signal receiving device is through ultrasound wave and the sender unit wireless connections being located on water-quantity regulating device.
Compared with prior art, this utility model can survey tune automatically according to arranging parameter, lowers labor intensity.Without docking, it is to avoid do not dock and cause survey to adjust unsuccessfully, there is no impact injury, improve the service life of instrument.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in figure: 1 eccentric injection mandrel, 2 eccentric orfices, 3 intelligent stoppers, 4 water injection holes, 5 signal receiving devices, 6 water-quantity regulating devices, 7 sender units.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings, but not as to any restriction of the present utility model.
A kind of without docking eccentric water injection device, as it is shown in figure 1, include the eccentric injection mandrel 1 being positioned at down-hole；It is provided with intelligent stopper 3 in the eccentric orfice 2 of eccentric injection mandrel 1；The hole wall of eccentric orfice 2 is provided with water injection hole 4；Intelligent stopper 3 is internal is provided with micromachine, battery, control circuit and signal receiving device 5；Signal receiving device 5 is through ultrasound wave and sender unit 7 wireless connections being located on water-quantity regulating device 6.
Embodiment
When being embodied as, do not change oil field existing eccentric injection mandrel structure, only docking is surveyed tune mode process separately, use a kind of mode do not docked to carry out surveying tune.This utility model uses intelligent stopper 3 unlike the prior art, intelligent stopper 3 is internal equipped with micromachine, battery, and control circuit etc., intelligent stopper 3 top is provided with signal receiving device 5, and water-quantity regulating device 6 lower end is provided with sender unit 7.Water-quantity regulating device 6 and intelligent stopper 3 use the spread of the rumours mode to communicate between the two, communication mode is ultrasound wave, water-quantity regulating device 6 sends an instruction to intelligent stopper 3 after setting parameter, being performed regulating command by intelligent stopper 3, after completing injection allocation requirement, upper water lift quantity regulating device 6 goes out well.
Claims (1)
1. a nothing docking eccentric water injection device, it is characterised in that: include the eccentric injection mandrel (1) being positioned at down-hole；It is provided with intelligent stopper (3) in the eccentric orfice (2) of eccentric injection mandrel (1)；The hole wall of eccentric orfice (2) is provided with water injection hole (4)；Intelligent stopper (3) is internal is provided with micromachine, battery, control circuit and signal receiving device (5)；Signal receiving device (5) is through ultrasound wave and sender unit (7) wireless connections being located on water-quantity regulating device (6).
