Description
Technical field
The invention belongs to belong to downhole instrument technical field of structures, in particular to a kind of underground relaying power supply unit and method.
Background technique
After oilfield exploitation to intermediary and later stages, it is general using to stratum fill the water or polymer flooding by the way of guarantee original
Oil yield.Injection well is layered commissioning process in oil field promotion and implementation many years, has played significantly for promoting oilfield economic benefit
Effect.Water injection well generally divides multiple layers of position, and accurately controlling each layer water injection rate is the key that guarantee output.
Oil field mainly uses in direct-reading packer detecting device lower going-into-well and carries out testing envelope to each layer of position at present, using direct read type water
Each layer water injection rate is adjusted in quantity regulating device lower going-into-well, by direct reading instrument measuring flow, temperature, water injection pressure and
Strata pressure etc..Envelope is tested, surveys to adjust and needs well testing truck repeatedly round-trip well site, multiple tripping in instrument surveys timing and is also required to adjust repeatedly
Each layer of position is just able to satisfy injection allocation requirement.Existing to survey based on the mode that artificial upper well survey is adjusted adjusts inefficient, field work by certainly
Right environment influences the drawbacks such as big, human cost height.With the continuous development of basic technology, intelligent seperated layer water injection has been carried out in oil field,
It can in real time by intelligent watering device and envelope is adjusted and tested to long term monitoring downhole flow, full-automatic survey.Intelligent distributor is gone here and there in tubing string
It is controlled to ground by surface power supply after connection by cable connection.Long cable internal resistance causes power loss big, and ground directly powers
Need to improve voltage, and ground high voltage power supply directly powers and electric circuit in well is be easy to cause to damage, the downhole intelligent distributor service life is short,
Reliability is not high.
Summary of the invention
In order to solve the above-mentioned technical problem, the adopted technical solution is that:
It is proposed a kind of underground relaying power supply unit, which is characterized in that the relaying power supply unit is by ground high voltage direct current
Source is first supplied to underground repeater, then is converted to low-voltage dc power supply by repeater and uses for intelligent distributor, in the underground
It is mounted on above top layer's intelligence distributor after device, the underground repeater connection ground control system and downhole intelligent injection allocation
Device, ground high-voltage DC power supply are first supplied to underground repeater, are converted to low-voltage dc power supply for intelligent distributor by repeater
It uses.
The present invention provides a kind of undergrounds to relay power supply unit, and ground high-voltage DC power supply is first supplied to underground repeater,
It is used being converted to low-voltage dc power supply by repeater for intelligent distributor, to improve the permanent worker of intelligent distributor system
Make reliability.
Detailed description of the invention
Fig. 1 is the schematic diagram that underground of the present invention relays power supply unit.
Specific embodiment
Below by specific embodiment, present invention is further described in detail, but these embodiments are only that citing
Illustrate, the scope of the present invention is not defined.
The present invention proposes a kind of underground relaying power supply unit, which is characterized in that the relaying power supply unit is by ground high pressure
DC power supply is first supplied to underground repeater, then is converted to low-voltage dc power supply by repeater and uses for intelligent distributor.
Underground repeater includes: central passage, tubing coupling (1), cable connector (2), circuit board (3), connection outer tube
(4), oil pipe adapter (5), lower contact (6), central seal pipe (7), power module (8), mounting bracket (9), top connection (10).
Underground repeater is mounted on above top layer intelligence distributor, be ground control system and downhole intelligent distributor it
Between bridge, both carried out data relay and also be downhole intelligent distributor power supply, ground high-voltage DC power supply be first supplied to underground relaying
Device is used being converted to low-voltage dc power supply by repeater for intelligent distributor.Repeater both ends are reserved respectively, and there are two electricity
Cable joint (2) realizes the disengaging connection of cable.Repeater top connection (10), central seal pipe (7), connects repeater lower contact (6)
Outer tube (4) composition sealing space is connect for electrically installing, circuit board (3), mounting bracket (9) etc. are fixed on repeater top connection
(10) on, mounting bracket (9) is used for fixed power source module (8).Circuit board (3), power module (8) are both designed as two sets, use
The power supply of positive-negative power mode dual system, improves system reliability.Connection outer tube (4) both ends are left-right rotary positive/negative thread, coaxial to twist
Tightly, guarantee installation direction and internal connecting wire not twisted wire when cable connector (2) assembly up and down.Central passage Φ 46 was used for
It is used when the other well loggings of decentralization, well testing quasi-instrument in water and tubing string.Since the limitation of cable connector (2) installation dimension cannot be direct
Screw thread is processed in lower contact on the repeater, therefore increases tubing coupling (1) and oil pipe adapter (5), upper end is tubing coupling
(1), lower end is that female realize of oil pipe adapter (5) one male one connect with water injection string tubing round thread.
By adopting the above-described technical solution, underground relaying power supply unit of the invention and method have the following characteristics that well
Lower repeater both carries out data relay, also matches for downhole intelligent as the bridge between well site measure and control device and intelligent distributor
Device power supply is infused high-voltage DC power supply is converted to low-voltage dc power supply and is greatly reduced respectively after relaying power supply mode using underground
The operating voltage of the intelligent distributor of layer, improves reliability and the service life of system, and reduce the power consumption of system.Repeater has
Redundancy Design has two sets of duplicate circuit systems, works on wherein can switch to another set of system after a set of failure, can
By property height.Using injection allocation communication among unit high reliablity after repeater, it is applicable in the long cable in underground.
Although the present invention has chosen preferable embodiment and discloses as above, it is not intended to limit the present invention.Obviously, it is not necessarily to here
Also all embodiments can not be exhaustive.Any this field researcher without departing from the spirit and scope of the present invention,
The design method and content that all can be used in embodiment disclosed above are changed and are modified to research approach of the invention, because
This, all contents without departing from the present invention program, research essence according to the present invention is to any simple made by above-described embodiment
Modification, Parameters variation and modification, belong to the protection scope of the present invention program.
