Abstract

The utility model relates to an oil field pipeline corrosion early warning system, which is composed of an abrasion sensor, a corrosion sensor, transmitters, a data bus, a remote data collector and a central processing unit. A probe of the abrasion sensor is buried in a pipe wall to be tested in sealing mode and connected onto the data bus through a first transmitter and a data line. A probe of the corrosion sensor is buried inside the pipe wall to be tested in sealing mode and connected onto the data bus through a second transmitter and a data connecting line. An interface module of a personal computer (PC) and the remote data collector are arranged at the data bus end. The output of the remote data collector is connected to the central processing unit. The central processing unit transmits the data to a displayer through analyzing management software. The oil field pipeline corrosion early warning system is comprehensive and advanced and comprehensively monitors corrosion speed, washout speed and fixed point thickness of the pipe network. The response speed of the monitoring system is quick, the sensitivity is high, and resolution is high. Collected corrosion data can be monitored on line at real time like procedure parameters, problems can be discovered timely, and reasons and methods can be found quickly.

Description

Oil field corrosion of piping early warning system
Technical field
The utility model relates to a kind of monitoring device, in particular for oil field corrosion of piping early warning system.
Background technique
At present gas-recovery station is more on the oil gas field, stand and gas recovery well has a very wide distribution, and is not easy to management, and stand an interior equipment and number of tubes constantly increase, the field technology of respectively standing how and the device type that is not quite similar more.In addition, the extraction pressure height of gas-recovery station rock gas, the CO of most of gas-recovery stations 2The very high and skewness of content, extraction well control fluctuation of service; Also have some gas-recovery stations time limit that comes into operation more of a specified duration, corresponding device pipeline etc. are transformed many, and equipment files is imperfect, and equipment does not have security monitoring facility etc.Because these odjective causes, there is polytype potential safety hazard in gas-recovery station, and the principal element that causes pipeline, equipment operation fault and security incident is that its internal corrosion is especially serious when containing aggressive medium in the corrosion under the various situations, particularly rock gas.Because failure accidents such as the body that the inside and outside corrosion of pressurized container, oven and pressure piping causes is bored a hole, broken, attenuate not only have a strong impact on ordinary production, personal safety causes great threat to equipment management personnel, tends to cause serious societal consequence.Existing corrosion of piping detection system is because structural design is unreasonable, and detection sensitivity is low, low-response, resolution are low, and influence detects effect.
Summary of the invention
The utility model is at the deficiency in the background technique, and a kind of oil field pipe corrosion early warning system that provides.
Oil field of the present utility model corrosion of piping early warning system is made up of abrasion sensor, corrosion sensor, transmitter, data/address bus, remote data collecting storage and central processing unit (CPU).The probe sealing of described abrasion sensor is embedded in the tested tube wall, is connected to data/address bus by first transmitter and datawire; The probe sealing of corrosion sensor is embedded in the tested tube wall, is connected to data/address bus by second transmitter and data connecting line.Data bus terminal is provided with the Interface Module and the remote data collecting storage of PC, and the output of remote data collecting storage is connected in central processing unit (CPU), central processing unit (CPU) by analysis management software with data transmission to display device.
As further improvement of the utility model, one and above abrasion sensor are arranged in this system, first transmitter and datawire by separately are connected in parallel to data/address bus.
As further improvement of the utility model, there be one and above corrosion sensor second transmitter and the data connecting line by separately to be parallel to data/address bus in this system.
The utility model is compared with background technique has following beneficial effect;
Oil field of the present utility model corrosion of piping early warning system, the energy system is corrosion rate, erosion rate, the fixed point thickness of on-line monitoring system comprehensive monitoring pipe network all sidedly, comprehensive advanced person of scheme, compare tradition corrosion detection scheme, the speed of response of on-line monitoring system of the present utility model is fast, highly sensitive, resolution is high; Compare tradition corrosion detection scheme simultaneously, the corrosion data that on-line monitoring system is gathered can by real time and on line monitoring, in time be pinpointed the problems as procedure parameter, finds reason and countermeasure rapidly.
Description of drawings
Fig. 1 is the utility model oil field pipe corrosion early warning system schematic representation.
Embodiment
Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:
Oil field of the present utility model corrosion of piping early warning system is made up of abrasion sensor, corrosion sensor, transmitter, data/address bus, remote data collecting storage and central processing unit (CPU).The probe sealing of described abrasion sensor 1 is embedded in the tested tube wall, is connected to data/address bus 4 by first transmitter 3 and datawire 7; The probe sealing of corrosion sensor 2 is embedded in the tested tube wall, is connected to data/address bus 4 by second transmitter 8 and data connecting line 9; Data/address bus 4 ends are provided with the Interface Module 10 and the remote data collecting storage 5 of PC, and the output of remote data collecting storage 5 is connected in central processing unit (CPU) 6, central processing unit (CPU) 6 by analysis management software with data transmission to display device 11.The utility model can monitoring system can corrode genetic analysis, improves preservative efficiency, system can be from the SCADA system access corrosion parameter, corrosion parameter and process parameter are associated, carry out comprehensive analysis, improve monitoring effect.
In this system one and above abrasion sensor 1, first transmitter 3 and datawire 7 by separately are connected in parallel to data/address bus 4, and second transmitter 8 and the data connecting line 9 that are one and above corrosion sensor 2 in this system by separately are parallel to data/address bus 4.Oil field of the present utility model corrosion of piping early warning system, the gas componant of energy real time on-line monitoring gas production wellhead is monitored the aggressive medium in the production on the one hand, reduces etchant gas from the source and enters pressurized container, conveyance conduit, oven.On the other hand, set up gas gathering station corrosion monitoring and analyzing and alarming system, realize the local etching situation of on-line monitoring gas pipeline, pressurized container and oven,, make limited investment solve more pipe safety hidden danger for daily management, maintenance, repair and the replacing of pipeline provides scientific basis.
