Abstract
The utility model discloses a cluster gas well automatic control adds agent device designs for realizing that local manual, timing are automatic and long-range adding agent and a tractor serves several wells add the purpose of agent, mainly including establishing high-pressure plunger pump, the many wells gate valve island in the control box and the solenoid valve of connecting, intelligent medicine controller and the wireless communication unit, direct current gear motor, storage battery and the charge controller of connecting, through the liquid level gauge etc. on the medical storage box and the medical storage box of pipeline connection high-pressure plunger pump. The device automatically transmits well mouth operation parameters to the gas collecting station by means of remote transmission and computer programming technology, operators set filling parameters according to production dynamic, and then the agent adding device is controlled by software in the station to add agent to each well, so that the agent adding operation of one machine with multiple wells is realized. The utility model discloses can realize the well site and add the remote operation of medicine and the automatic acquisition of addict data, can meticulous regulation and control addict frequency and dose, rate and production life when improving the gas well and opening the well reduce the well head and add medicine operating cost, reduce artifical intensity of labour by a wide margin, the running-out during avoiding manual operation is dripped and is leaked the phenomenon.
Description
Technical field
The utility model relates to the automatic control of a kind of clump of formula gas well and adds the agent device, belongs to gas field natural gas extraction technical field.
Background technology
In the process of gas field natural gas extraction, along with going deep into of exploitation, stratum energy descends gradually, and water outlet appears in the stratum, and the fluid-carrying capability of natural-gas weakens, the pit shaft hydrops is increasing, if can not in time discharge the pit shaft hydrops, can cause well head pressure to reduce, increase liquid to the back pressure of gas-bearing formation, cause gas production sharply to descend, even the dried-up well phenomenon occurs.Traditional hydrops method of discharging mainly is filling frother or input bubble rod row in pit shaft, and the method efficient is low, and it is untimely to annotate, and can have a strong impact on the normal production of clump formula gas well and the extraction of natural gas.
The method of automatic injection Ji or automatic switching bar device successively occurred in recent years installing at well head, this technology can significantly reduce hand labor intensity, improves injecting efficient.But along with increasing of gas field cluster well group, the mode of a set of equipment filling a bite well originally can not satisfy the demand that clump formula gas well adds agent.
Summary of the invention
The purpose of this utility model is to provide the automatic control of a kind of clump of formula gas well to add the agent device, and it can realize local manual, the timing automatic and long-range function that adds arbitrarily agent, and what reach the many wells of a machine adds the agent purpose.
Concrete technical scheme of the present utility model is as follows:
Be provided with the high-pressure plunger pump that connects DC speed-reducing in the control cabinet, high-pressure plunger pump connection outlet pressure meter and many Jing Xuantongfadao; Each outlet of many Jing Xuantongfadao connects respectively electromagnetic valve separately, and each electromagnetic valve all connects the dosing mouth of a bite gas well through ball-and-seat separately.Be provided with intelligent dosing controller in the control cabinet, intelligent dosing controller connects each electromagnetic valve, wireless communication unit and DC speed-reducing connected to one another, batteries and charge controller, and charge controller connects outdoor solar panel and wind-driven generator simultaneously.
Hold medicine-chest casing top and be provided with dosing lid and dosing mouth screen pack, bottom half is provided with liquid outlet and liquid outlet screen pack.The casing outside is provided with content gauge, and content gauge is provided with the sensor that connects intelligent dosing controller.Hold medicine-chest and be located in the ground, by the high-pressure plunger pump in the pipeline connection control cabinet.
The utility model is by Long-distance Transmission Technologies and computer programming, by transmission radio station with the operational factor automatic transmission of the well head control software to gas gathering station, operating personnel are according to the production dynamic setting filling parameter of the different individual wells of cluster well group, send instruction to well group RTU by the interior software of standing again, control adds the agent device every mouthful of well is added agent automatically, realizes that the agent that adds of the many wells of a machine operates.
The utility model can be realized the operated from a distance of well site dosing and add the automatic collection of agent data, can add agent frequency and dosage by finely regulating, strengthens the accurate management of dosing technology, the needs of competent digital management; Rate and Production Life in the time of improving gas well and drive a well reduce the well head medicine-adding operating cost, minimizing personnel and vehicle employ number of times, significantly reduce hand labor intensity, the evaporating, emitting, dripping or leaking of liquid or gas phenomenon when avoiding manual operation reduces the impact on environment.

The specific embodiment
Further specify referring to figs. 1 through 3 couples of embodiment of the present utility model:
Embodiment:
The automatic control of clump formula gas well add the agent device mainly by solar panel 1, wind-driven generator 2, intelligent dosing controller 3, charge controller 4, batteries 5, DC speed-reducing 6, hold medicine-chest 7, high-pressure plunger pump 8, many wells sluice valve island 9, electromagnetic valve 10, ball-and-seat 11, wireless communication unit 12, pressure meter 13 and control cabinet 14:
Hold medicine-chest 7 casing tops and be provided with dosing lid 72 and dosing mouth screen pack 73, bottom half is provided with liquid outlet 74 and liquid outlet screen pack 75; The casing outside is provided with the content gauge 71 of magnetic turning over type, and content gauge 71 is provided with the sensor that connects intelligent dosing controller 3, to realize the long-range demonstration of liquid level.Hold medicine-chest 7 and be located in the ground the position of 1m, connect high-pressure plunger pump 8 in the control cabinet 14 by pipeline.
The course of work that the automatic control of clump formula gas well adds the agent device is as follows:
At first, utilize portable suction pump that medicine is injected from dosing lid 72 and hold in the medicine-chest 7, injection rate can be checked by content gauge 71.Connect control cabinet 14 power supplys, after indicator lamp is bright, on control panel, " manual/auto " switch is located at " automatically " position, then open gas gathering station control software, set adding amount and the filling cycle of every mouthful of well, control software can according to the working time of the discharge capacity automatic setting pump of high-pressure plunger pump 8, send to selected cluster well field by transmission radio station with the dosing instruction subsequently.After control cabinet 14 received instruction, RTU was converted to the signal of telecommunication with data-signal automatically, realized the opening and closing of pump by the power switch of control high-pressure plunger pump 8; RTU realizes that by many wells of control sluice valve island electromagnetic valve 10 medicine of every mouthful of well injects; RTU is responsible for passing the filling record of every mouthful of well and the level condition of holding in the medicine-chest 7 back gas gathering station, realizes well head Automatic Dosing data acquisition, monitoring and control.
