Background technique
Oilfield transportation system number of tubes is huge, and corrosion condition is different under various circumstances, and the corrosion of pipeline is to oil field
Production and operation bring very big difficulty.Corrosive pipeline perforation such as will cause environmental pollution, fire at personal injuries and the property loss.Cause
This, carries out corrosive pipeline condition monitoring, grasps corrosion condition in time, can be pipeline controllable management, reducing security risk seems
It is particularly important.
Corrosive pipeline is mainly caused by microorganism sulfate reducing bacteria (SRB).Water flooding major part water source
From self-produced sewage, in sewage contain a large amount of SRB, under certain condition the sulfate ion of SRB be reduced into divalent sulfur from
Son, and then form by-product hydrogen sulfide.And vulcanize the acidic environment that Hydrogen Energy makes circulation part occur, make these places
Metal is corroded, at the same vulcanize Hydrogen Energy and stainless steel, copper alloy, nickel alloy certain components generate stable sulfide, and
The composition for destroying these metals makes these metals by pitting.
As it can be seen that the direct reacting pipe corrosion condition of SRB rate of corrosion.And SRB average corrosion rate is monitored, it can be examined using test piece
Survey method.Test piece is suspended in water filling (mixing defeated, oil-collecting) system, under normal production conditions, is taken out after 30 ± 2d, according to test
The loss amount of front and back test piece calculates average corrosion rate, so for injection water management technical staff adjust sterilization scheme provide test according to
According to.
However, there are no look into other than the utility model patent " wellhead of water injection well hanger device " of this research team application
Read other dedicated units that test piece can be suspended in water filling system.

" O " shape sealing ring is sleeved on the screw rod, and the upper end of test piece protective case is screwed to pressure cap, and " O " shape sealing ring plays sealing and makees
With；The screw rod lower end is equipped with insulation test piece support, and inverted " recessed " shape gap, test piece are arranged at the insulation test piece support bottom
It is mounted on the middle position of gap, test piece fixing bolt sequentially passes through an extension end, test piece and " recessed " shape of " recessed " shape gap
Test piece, is fixed on the middle position of gap by another extension end of gap；
In use, liquid-transport pipe-line is drilled, by the oil field pipe corrosion monitor according to test piece protective case
Inner, the direction of pressure cap outside is inserted into liquid-transport pipe-line, and to the gap between oil field pipe corrosion monitor and hole into
Row sealing；When needing to monitor, test piece is screwed on test piece protective case with pressure cap.
Above-mentioned oil field pipe corrosion monitor, the screw rod bottom are provided with blind hole and vertical screw with screw coaxial
First through hole；The second through-hole of vertically insulated test piece support is provided with above insulation test piece support；The blind hole and insulation examination
Plate rack forms clearance fit, and the first through hole is identical with the second through-hole diameter；Insulation test piece support is inserted into blind hole, is adjusted
Whole first through hole and the second through-hole are coaxial, and pin is passed through from first through hole and the second through-hole, and edge test piece support is fixed in realization
Onto screw rod.
The utility model has the advantages that under the structure of the utility model oil field pipe corrosion monitor, provide not only a kind of new
The dedicated unit that test piece can be suspended in water filling system, and lacing film can be realized only by the operation for screwing pressure cap
Installation and removal, installation maintenance are more convenient.
