2Toxic and harmfuls such as S.Toxic and harmful overflows from well head, has potential menace near staff well head.
At present, do not have supporting real-time parameter monitoring system at oilfield acidifying scene, the field technician is difficult to grasp the quantity of construction parameter and the contained toxic and harmful of ambient air.Can't guarantee constructor's safety like this; Can not implement effectively monitoring and analysis to the data of oil well acidation process.
The utility model content
The purpose of this utility model is: a kind of oil well acidation on-stream monitoring device is provided, can monitors the well head toxic and harmful concentration and the warning that in time exceeds standard on every side, solve staff's safety problem; Monitoring oil well acidation parameter improves the oil well acidation operation quality.Overcome in the acidizing treatment process and can not monitor construction parameter; Can't guarantee the deficiency of constructor's safety.
The technical solution adopted in the utility model is: oil well acidation on-stream monitoring device, mainly be made up of fixed ultrasonic flowmeter, four unification gas detecting instruments, pressure monitor, pH value detector, A/D converter, remote-terminal unit (RTU), central processing unit (CPU) and notebook computer, it is characterized in that: fixed ultrasonic flowmeter, four unification gas detecting instruments, pressure monitor are connected an A/D converter respectively with the pH value detector.A/D converter connects a remote-terminal unit (RTU) and a central processing unit (CPU).Between remote-terminal unit (RTU) and notebook computer, adopt the 100M wireless telecommunications to be connected.
That described fixed ultrasonic flowmeter adopts is TUF-2000S, and what fixed ultrasonic flowmeter adopted is that ultrasonic wave detects, and can monitor the strong acid fluid flow that passes through, and there is sale in market.
What described four unification gas detecting instruments adopted is the EM-4 type; (also claim: what the pH value tester) adopt is the TES1380 type to the pH value detector; What pressure monitor adopted is the YHY-D-I type, range 0～20 MPa.
The function of oil well acidation on-stream monitoring device has:
1, video monitoring: the video data acquiring instrument carries out real-time video monitoring to the job site to be recorded, and the video of gathering is encoded by computer programming software and compresses, and finally becomes optical disc storage by the CD writer imprinting.
2, the monitoring of toxic and harmful and warning: monitor the concentration of each pernicious gas constantly of job site in real time, when concentration exceeds setting value, report to the police, and can generate the monitoring curve of various pernicious gases in real time.
3, the pressure of acid solution, flow monitoring: when carrying out acidizing treatment at the construction field (site), inject the flow of acid solution and the pressure of generation, by the control of host software, add up and note when construction different situations and inject how many effects of producing of flow, be convenient to analyze and to the contrast of construction effect.
4, the acid solution pH value detects: monitor each acid solution pH value constantly of job site in real time.
The beneficial effects of the utility model: the utility model oil well acidation on-stream monitoring device, adopt four unification gas detecting instrument monitoring well heads toxic and harmful concentration on every side, solved personnel's safety problem; Adopt fixed ultrasonic flowmeter, pressure monitor, pH value detector, monitoring oil well acidation parameter can instruct acidizing treatment, improves the oil well acidation operation quality.Solved in the acidifying measures engineering construction parameter problems of monitoring in real time effectively,, be convenient to on-the-spot supervision and measure effect analysis construction parameter (pressure of acid solution, flow and pH value) automatically generated data curve; The data wireless of gathering is reached notebook computer outside the 100m, the reliability and the safety that have improved acidizing treatment.
