In order to obtain the corrosion law and safe service life of different tubing steels in acid gas reinjection environment, the acid gas refilling well conditions were simulated by using high temperature autoclave. The corrosion weight loss experiment was carried out under the conditions of 90~150 Ä C, H2S content of 55 vol% and CO2 content of 45 vol%. The corrosion properties of T95, PIIOSS and G3 steels were studied at different temperatures. The corrosion products were characterized by SEM and EDS. Finally, the corrosion life of the tubing columns was predicted basing on the uniform corrosion rate. The results show that the corrosion rate of T95 and PIIOSS steels increase first and then decrease in the liquid phase with the increase of temperature, reaching the maximum at 120 °C, 3:379 mm/ a for T95 steel and 0. 842 6 mm/ a for PIlOSS steel. In t he gas phase, the corrosion rate of two steels increase with the increase of temperature, reaching the maximum at 150 °C, 0. 2490 mm/a for T95 steel and 0. 2:3:3 9 mm/a for PIIOSS steel. G:3 nickel-based alloy steel exhibits good corrosion resistance and meets the oilfield corrosion control index of 0. 076 mm/a under all working conditions. The service life of T 95 tubing steel is 2. 8 years and that of PIIOSS tubing steel is 6 years under the harsh working conditions of liquid ph;1se at 120 °C ; the service life of T 95 tubing steel is 14. 9 years and that of PIIOSS tubing steel is 21.3 years under the severe conditions of gas phase at 150 °C. This article clarifies the corrosiveness and safe service life of three tubing steels in acid gas reinjection environment, which provides a basis for selecting materials of acid gas reinjection wells and formulating the targeted corrosion protection measures.

目的探讨他克莫司(FK506)对肝移植患者外周静脉血IL-2、IL-10基因表达的影响及意义。方法选择接受原位肝移植患者60例,均采用FK506+甲基强的松龙+吗替麦考酚酯三联用药治疗。肝移植术后第1、3周取外周血,检测血清ALT、AST及外周静脉血IL-2、IL-10基因表达。结果与肝移植术后1周比较,肝移植术后3周患者血清ALT水平明显降低(P<0.05),而血清AST水平变化不明显(P>0.05);肝移植术后3周外周静脉血IL-2基因表达明显降低(P<0.05),IL-10基因表达明显升高(P<0.01)。血清ALT水平与IL-2基因表达呈正相关,与IL-10基因表达呈负相关(P均<0.05);血清AST水平与IL-2、IL-10基因表达均无相关性(P均>0.05)。结论FK506可能通过影响外周静脉血IL-2、IL-10基因表达,从而抑制免疫排斥,诱导免疫耐受。 [ABSTRACT FROM AUTHOR]
