Technical field
The utility model relates to chemicals dosing plant, particularly a kind ofly realize regularly, quantitatively, the downhole intelligent chemicals dosing plant that adds continuously.
Background technology
Traditional mechanical type down-hole drop doser can not be controlled the dosing flow velocity, can't realize soup timing, quantitatively add, trimestral often dose just adds less than a week and is over.The dosing of oil jacket annular space drop has the well of packer for the down-hole, can not add the antisludging agent antiscale from the oil jacket annular space, can't implement dosing to cover pressure-controlled oil well.It is big to different blocks medicine solution temperature control difficulty that medicine solidifies dosing method, the block bad adaptability, and the curing chemistry medicament stops up oil flow channel after dissolving easily in tail pipe.
The utility model content
The purpose of this utility model provides and a kind ofly realizes regularly, quantitatively, the downhole intelligent chemicals dosing plant that adds continuously.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of downhole intelligent chemicals dosing plant, it is characterized in that: form by drug storage pipe and control system for adding drugs two parts, the drug storage pipe is serially connected in the top of control system for adding drugs, described control system for adding drugs comprises the control chip that is used to provide the minitype speed reducing motor of power and regularly sends action command to motor, described motor upper end is connected with according to the motor action frequency battery pack to the motor power supply regularly, and the lower end is connected with the bearing rod that is used for transferring power.
Preferably, described bearing rod lower end is connected with the emery wheel gate valve, and the emery wheel gate valve is opened in described driven by motor bearing rod, the emery wheel gate valve rotary course, and chemical agent is the current limliting by emery wheel under the effect of revolving force, by the quantitative pit shaft of clamp-oning.
Preferably, be provided with batching pig in the described drug storage pipe, be used for the medicine of pit shaft liquid and drug storage pipe is isolated.
Preferably, described control chip doser action time started that computer is default on ground, open the frequency and stop actuation time and note, then according to default dosing system, regularly send action command to motor.
Preferably, described battery pack adopts 3.6V high temperature lithium-thionyl battery, provides power to motor, chip, according to the difference in dosing cycle, can be two joints or the series connection of four batteries.
Preferably, described motor and battery pack all are subjected to described chip controls, battery according to chip instruction regularly to the motor power supply, motor is started working after receiving the action command that chip sends, and drives bearing rod, the rotation of emery wheel gate valve.
Owing to adopted technique scheme, the utlity model has following beneficial effect:
(1) by the electronic intelligence control technology, realized the down-hole chemical agent regularly, quantitatively, add continuously, it is controlled that add dose every day.
(2) battery life is grown, can be reached more than 1 year, has satisfied on-the-spot inspection pump, dosing cycle requirement.
(3) the doser central tube all adopts the stainless steel anti-corrosion material, and long service life can repeat to go into the well, and reduces cost of investment.
The setting of (4) dosing system is flexible, and it is 50～80ml/ time that each unlatching discharges dose, and the opening time can be accurate to 1 minute at interval, satisfied the dosing demand of different wells, and is applied widely.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
According to embodiment the utility model is described in further detail below.
As shown in Figure 1, a kind of downhole intelligent chemicals dosing plant, form by drug storage pipe 5 and control system for adding drugs two parts, drug storage pipe 5 is serially connected in the top of control system for adding drugs, control system for adding drugs comprises the control chip that is used to provide the minitype speed reducing motor 2 of power and regularly sends action command to motor, motor 2 upper ends are connected with according to the motor action frequency battery pack 1 to the motor power supply regularly, and the lower end is connected with the bearing rod 3 that is used for transferring power, and described bearing rod 33 lower ends are connected with emery wheel gate valve 4.
Chip is the core component of intelligence control system, the function of chip is doser action time started that computer is default on ground, open the frequency and stop actuation time (be set the blanking time that per twice down-hole switch opened) notes, then according to default dosing system, regularly send action command to motor 2.
What motor 2 adopted is minitype speed reducing motor, good stability, and torsion is big, makes with special composite material, has high temperature resistant 120 ℃, high pressure 50Mpa and in the medium-term and long-term characteristics of working of corrosive liquids.The major function of motor 2 is after receiving the action command that chip sends, battery pack 1 according to the chip instruction regularly to motor 2 power supplies, motor 2 begins action, motor 2 is power producers of dosing.
Emery wheel gate valve 4 begins rotation under the drive of bearing rod 3, realize the unlatching of gate valve, and gate valve also has a metering function to medicament simultaneously, and quantitative medicament is squeezed into pit shaft by the emery wheel gate valve.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other multi-form variation and changes on the basis of the above description.Here can't give exhaustive to all embodiments.Everyly belong to the row that conspicuous variation that the technical solution of the utility model amplifies out or change still are in protection domain of the present utility model.
