Materials Selection for Various Service Conditions不同环境下材料的选择 ? Non-corrosive/Mildly sour service无腐蚀，微酸性环境 ? CO2 Corrosion/Intermediate Service(Wt. Loss Corrosion)二氧化碳腐蚀，质量损失腐蚀 ? Highly corrosive service (high CO2/high H2S/high T) 严重腐蚀环境（高温，高含硫，高含二氧化碳） ? Water injection service注水环境 Completion Equipment Materials as a Function of Customers Tubing与油管相对应的工具材质 Completion Equipment Material完井工具材质 ?4130/4140 ? 4130 Modified (90 ksi), T-95, 925 for polished bores ?410/13Cr, 420 Mod. ?Super 13Cr ?25Cr or 718 ?925, 718 ?725 Tubing Material油管材质 ?J-55, C-75, N-80, L-80 ?C-90/ T-95 ?13Cr (420 Mod.) ?Super 13Cr ?22/25Cr (Duplex) ?825 ?C-276 Materials Selection Guide材质选择指南 Alloy Recommended推荐使用合金 ? 4130/4140 (polished bores打磨的口径 9 Cr-1 Mo) ? 4130 External外表 (22 HRc max) 9 Cr-1 Mo Flow Wetted ? 22/25Cr S.S. ? 22/25Cr S.S. ? 925/718 (Ni-Cr) alloys ? 725, C-276, etc. Environment使用环境 ? Non-Corrosive Service无腐蚀环境 ? Slightly Corrosive to Moderately Corrosive Low H2S, CO2 + Water Low Temperatures, 250°F低腐蚀环境，低含硫，Co2，低温小于250F ? CO2 Corrosion, Trace H2S二氧化碳腐蚀，微硫化氢 CO2 Corrosion, Low H2S Higher Temperatures 二氧化碳腐蚀，低硫化氢，更高温 Severely Corrosive H2S, CO2, up to 300°F 严重的硫化氢，二氧化碳腐蚀，高温至300F ? Severely Corrosive + Temperatures over 300°F严重腐蚀，温度超过300F Equipment for Standard/ Low H2S Service标准或低含硫环境的材质选择 ? Low alloy steels, 4130/4130 used for most completion equipment.低合金钢，4130适用于绝大多数的完井工具 ? Flow wetted components in safety valves are made from 9Cr-1Mo. Polished bore components ie. Nipples are made from 9Cr-1Mo or higher alloys.流体经过部分材质是9Cr-1Mo，外表面材质9Cr-1Mo或者更高质量的合金。 ? LA steels and 9Cr-1Mo are usually heat treated to 80ksi YS and hardness controlled to HRC 22 per NACE std. LA合金和9Cr-1Mo经过回火处理后可以达到80Ksi屈服强度，HRC硬度22. CO2 Corrosion and Intermediate Service 二氧化碳腐蚀环境 ? Prime consideration is given for weight loss corrosion issues. Goal is 10-20 year service life and beyond if required.首要考虑的是由于质量损失引起的腐蚀，目标是10-20年的服务年限，或者更高。 Generally, 13Cr, Super 1
