Specific embodiment one:
1, testing sequence:
Select sewer oil (directly purchasing in market, acid number 1.10mgKOH/g, saponification value 191.14mgKOH/g); Test materials is chosen to be down-hole string material J55 steel, and its chemical composition is in table 1. Sample is processed into sheet specimens (size: 50 �� 10 �� 3mm), is used as corrosion weight loss test and corrosion electrochemistry test after it is processed. The chemical component table 1 of sample material is as follows:
| Material | C | Si | Mn | P | S | Ni | Cr | Mo |
| J55 | 0.38 | 0.27 | 1.29 | 0.02 | 0.01 | / | 0.09 | / |
Above-mentioned obtained sanitas is uniformly sprayed on J55 steel strip, test piece is placed in the loft drier of 60 DEG C freeze-day with constant temperature 15min, repeat said process three times, obtain scribbling the J55 steel test piece of sanitas coating.
Original J55 steel test piece and the J55 steel test piece that scribbles sanitas coating are suspended in the oil field extracted water of 40 DEG C, after constant temperature soaks 72 hours, with scavenging solution (500mLHCl, 20g hexamethylenetetramine, 500mL distilled water) clean test piece, remove the corrosion product of specimen surface, after processing with dehydrated alcohol again, quality before and after test, presses, according to the reduced gravity situations of test piece, the erosion rate that formula (1) calculates test piece, and observes the microscopic appearance of corrosion sample.
(1)
In formula: F is erosion rate (mm/a); m0And m1It is respectively quality (g) before and after test piece corrosion; S is the long-pending (cm of strip2); T is for hanging sheet time (d); �� is test piece material density (g/cm3).
Galvanic corrosion is tested, adopt electrochemical workstation (CHI660B, Shanghai Chen Hua company) measure the corrosion resistance nature of sample, test carries out in oil field extracted water, adopts three-electrode system to carry out the test of dynamic potential polarization curve, take saturated calomel electrode as reference electrode, platinum electrode is supporting electrode, J55 steel test piece, as working electrode, uses epoxy encapsulation testing sample, and exposed area is 1cm2, electric potential scanning speed is 0.2mV/s.
2, interpretation:
Fig. 1 is the erosion rate of this sanitas process front and back J55 steel in oil field extracted water. As can be seen from the figure, J55 steel is under the effect of sanitas, and its erosion rate reduces greatly than the blank sample erosion rate under same experimental conditions, is reduced to 0.3218mm/a by original 1.2875mm/a, and erosion rate reduces nearly 75%.
Fig. 2 is the microscopic appearance that before and after the process of this sanitas, J55 steel corrodes in oil field extracted water. As we can see from the figure, its surface corrosion of J55 steel processed without this sanitas is obvious, and strip exists the erosion of obvious point (hole), and has corrosion product to generate; And obviously alleviate through its surface corrosion of J55 steel of sanitas process, surface only has a small amount of corrosion product to generate, and J55 steel is played a very good protection by sanitas.
Fig. 3 is the electrokinetic potential scanning polarization curve figure of this sanitas process front and back J55 steel in oil field extracted water. As seen from the figure, after the process of this sanitas, the polarization curve of J55 steel sample there occurs and moves to left phenomenon, and its corrosion potential is higher than untreated J55 steel sample, shows that its corrosion resistance nature of J55 steel after processing increases. Polarization curve is carried out matching, its corrosion potential (Ecorr) and corrosion electric current density (icorr) arrange in table 2.It may be seen that after this sanitas processes the E of J55 steelcorrFor-0.409V, higher than untreated J55 steel Ecorr=-0.461V, shows that the stability of J55 steel in oil field extracted water after processing is improved; Its i simultaneouslycorrIt is 2.09 �� 10-5A/cm2, than untreated J55 steel icorr=7.94��10-5A/cm2Have dropped nearly 2 times, show that this sanitas can reduce the corrosion speed of J55 steel in oil field extracted water. Table 2 is as follows:
| Sample | Ecorr (V) | icorr (A/cm2) |
| Before sanitas process (a) | -0.461 | 7.94��10-5 |
| After sanitas process (b) | -0.409 | 2.09��10-5 |
