Abstract
The invention discloses an automatic filling system for a gas well defoamer, which comprises a differential pressure sensor, a processor and an injection pump, wherein the differential pressure sensor is used for detecting liquid flow pressure in a gas production pipeline and transmitting the detected pressure signal to the processor; the processor has a preset liquid flow pressure trigger value, and the received liquid flow pressure value is compared with the trigger value, wherein if the real-time value is higher than the trigger value, the processor conducts the power supply of the injection pump to inject the defoamer, and if the real-time value is lower than the trigger value, the processor disconnects the power supply of the injection pump to stop the injection pump; and thus the injection pump is controlled by the processor to start or stop the addition of the defoamer. The automatic filling system for the gas well defoamer is capable of filling the defoamer according to the liquid production condition of a gas well in real time, thereby ensuring that the defoamer can play a role in time when liquid is produced; and when no liquid is produced, the addition of the defoamer can be quickly stopped, thereby avoiding untimely and unreasonable conditions caused by artificially starting pump injection, saving a large amount of the defoamer and improving the defoaming effect.
Description
Technical field
The present invention relates to the exploitation of a kind of gas well field, specifically a kind of gas well defoamer automatic filling system.
Background technology
For the water-producing gas well needing filling foam discharging agent, the formation water of discharging needs process because entrained foam amount is more, the processing method of formation water foam conventional is at present that artificial start by set date injection pump adds defoamer in the liquid of output, in actual production process, ubiquity defoaming effect is undesirable, main cause does not have a continuity because gas well produces water, by manual observation gas well produce water number be difficult to again accurate judgement, so have impact on the real-time filling of froth breaking medicament, foam killer filling during frequent generation anhydrous output, the problem of defoamer is not added again when having aquatic products to go out, defoaming effect is have impact on again while wasting defoamer like this.
Summary of the invention
The object of the invention is to: for the deficiency of above problem, provide a kind of simple to operate, produce water signal accuracy of judgement, defoamer filling in time, automaticity is high, science can control the system that defoamer annotates in real time.
The technical solution used in the present invention is:
A kind of gas well defoamer automatic filling system, described loading system comprises:
-differential pressure pick-up, the pressure signal detected for detecting the liquid flow pressure in aerogenesis pipeline, and is real-time transmitted to processor by described differential pressure pick-up;
-processor, is preset with liquid flow pressure activated value in described processor, this value is the liquid flow pressure under normal circumstances in aerogenesis pipeline; The real-time liquid flow pressure that described processor is used for differential pressure pick-up to send is made comparisons with setting trigger value, if instantaneous value is higher than trigger value, the power supply of processor conducting injection pump, injection pump action, if instantaneous value is lower than trigger value, processor cuts off power supply, the injection pump shutdown of injection pump;
-injection pump, described injection pump under the control of a processor, for defoamer being injected the working fluid in aerogenesis pipeline.
Described differential pressure pick-up is arranged on the orifice plate at gas-liquid separator place.
The invention has the beneficial effects as follows: real-time foam killer filling can be carried out according to gas well production fluid situation, when guaranteeing there is liquid output defoamer can work in time, no liquid output time, defoamer can stop rapidly adding, avoid manually starting infusion not in time, irrationality, save froth breaking medicament and improve defoaming effect simultaneously in a large number.
Accompanying drawing explanation
Fig. 1 is operating principle flow chart of the present invention.
Detailed description of the invention
According to Fig. 1, the present invention is a set of gas well defoamer automatic filling system, and this automatic filling system comprises differential pressure pick-up, processor and injection pump.Differential pressure pick-up is used for the liquid flow pressure detected in real time in aerogenesis pipeline, and the pressure signal detected is transferred to processor in time; Processor is for judging and process the live signal that differential pressure pick-up transmits, the trigger value (this value is by utilizing monitoring of software to gather the differential pressure rate of change that obtains of intelligent controller in advance, the differential pressure changing value in the normal gas producing found and water outlet situation) of liquid flow pressure is preset with in processor; According to trigger value, control startup and the stopping of injection pump; Injection pump and defoamer UNICOM, for injecting defoamer in aerogenesis pipeline.
This gas well defoamer automatic filling system operationally, differential pressure pick-up is arranged on the orifice plate of gas-liquid separation place, when in well, liquid produces, have liquid to flow out, liquid flow pressure in differential pressure pick-up Real-Time Monitoring aerogenesis pipeline, this flowing pressure value is transferred to processor, the liquid flow force value that differential pressure pick-up sends by processor carries out record, amplify process, then the trigger value set in this value and processor is compared, if this value is higher than trigger value, the power supply of processor conducting injection pump, injection pump works, ready defoamer is injected aerogenesis pipeline, inject in defoamer certain hour, by the flowing pressure of liquid in differential pressure pick-up again received well, again feed back to processor, if when instantaneous value is lower than trigger value, processor cuts off injection pump power supply, injection pump is shut down, stop adding defoamer.
Claims (2)
