Description
Technical field
The present invention relates to monitoring device field in storage tank, Multifunctional corrosion monitors in real time in particularly a kind of gun barrel
Device and method.
Background technology
Domestic each elephant passes through the exploitation of decades, into High water cut, even super-high water-cut stage, extraction
Liquid composite water cut is even as high as more than 90%.Because extraction water salinity is high, chloride ion content is big, and containing carbon dioxide,
The microorganisms such as hydrogen sulfide, silt and sulfate reducing bacteria, it is right along with interactions such as water temperature is higher, flow velocity, change of flow state
Water-oil separating top tank structure causes heavy corrosion, turns into one of principal element for restricting oilfield safety production increasingly.Meanwhile most oil
Field is generally using the exploitation of multilayer position and Produced Liquid mixed processing technique, rather than with incrustation ion (such as Ca in layer Produced Liquid2+、
CO3 2-、SO4 2-Deng) content difference is larger, the precipitation such as calcium carbonate, calcium sulfate is easily generated during mixing.This causes oil field operating cost to increase
Add, cause huge economic losses, or even trigger safety and environmental pollution accident.
To slow down in-tank corrosion, sacrificial magnesium alloy anode block generally is installed in tank bottom, while in top tank structure applying coating
So as to by oil-water media and top tank structure metallic matrix physical isolation.However, sacrificial anode block is because of its own quality problems and sinks
Deposition or absorption of the product thing (silt, dirt, microorganism) on its surface, cause the too fast dissolving of sacrificial anode block, uneven dissolution very
It is extremely insoluble；Or because sacrificial anode block is not connected closely with tank body or because sacrificial anode block surface deposits dirt, causes it to tank
The protecting effect of body is not good enough.Moreover, coating quality itself, coating process is different, cause its protective value to tank body different.
In addition, production fluid of the fluid because summarizing different layers position and different blocks oil well in tank, the composition of the medium in different time and
Acidity is different, causes the fluctuation of its corrosivity larger, causes coating bubbling or even depart from, and loses the protectiveness to tank body, local de-
From even can also form " big negative electrode primary anode ", aggravate the local corrosion of tank body.
The monitoring mode of generally use monitors for regular stopping production can opening at present：First, seeing whether sacrificial anode block surface dissolves
Uniformly, two it is to look at whether tank inner surface coating has bubble and peeling phenomenon, third, if any peeling, monitors the wall of tank body
It is thick.Its shortcoming is：First, needing to stop production, the normal production in oil field is influenceed；Second, need clear tank, it is desirable to cleaned in tank, without residue
Oil, water, debris, the workload such as mud it is big；Third, the time delay of monitoring, it is impossible to which the top tank structure of reflection separation in real time is thinned situation, is situated between
Whether the corrosivity of matter, the protecting effect of sacrificial anode block and its size reach critical.Under such a military service working condition, tank body
Inner wall corrosion is still serious, and does not cause knockout drum premature failure by timely discovery, reparation.
The content of the invention

Steel curved beam corrosion rate is higher or significant change may occur for coating sample, then needs to shorten monitoring cycle；If pH value is very
It is low, then need to monitor dissolution degree, the situation and tank body wall thickness of coating of sacrificial anode block after stopping transportation, clear tank, carry out related peace
It is complete to assess.
Instantiation 2：If computer related software " Cl-Shown Cl under concentration " selection card item-Concentration data fluctuates
It is bigger, illustrate to pass through Cl-Each gathering line of probe monitoring carrys out the situation of change of liquid, need to take the necessary measures, and avoids because individual
The pretreatment of other well Produced Liquid is not in place and the heavy corrosion water-oil separating tank and shorten its service life, or because Produced Liquid has
There is strong fouling tendency and cause sediment composition in sacrificial anode block surface serious scale, and then influence the protection of sacrificial anode block
The output of electric current.
Instantiation 3：If voltage/output current of the sacrificial anode block of gun barrel tank bottom is unstable or higher/inclined
It is low, it should in time stop to note in the case of it is determined that other specification changes without larger fluctuation, be incorporated to tank inspection or change in time and sacrifice sun
Pole block, it is ensured that protecting effect of the sacrificial anode block to water-oil separating tank.
Technical scheme is not limited to the limitation of above-mentioned specific embodiment, and every technique according to the invention scheme is done
The technology deformation gone out, each falls within protection scope of the present invention.
