雅克拉凝析气田位于新疆塔里木盆地,气藏具有埋藏深(5000～6000 m)、地层压力高(56～58.00 MPa)、温度高(146～150℃)、腐蚀环境复杂(高CO2、高Cl-、低PH、低H2S)等特点,单井高压集输管线采用抗腐蚀的06Cr13不锈钢管材。本文从06Cr13不锈钢性能、材料及其焊接性能出发,介绍了06Cr13不锈钢管材焊接技术及其要求,确保使高压集输管线用06Cr13钢管的焊接性能指标满足设计要求,确保高压集输管线后期正常运行。
The Yakela condensate gas field is located in the Tarim Basin in Xinjiang. The gas reservoirs are buried deep (5000-6000 m), formation pressure is high (56-58.00 MPa), high temperature (146-150 ℃), corrosive environment is complex (high CO2, high Cl -, low PH, low H2S) and other characteristics of single-well high-pressure gathering pipe corrosion resistant 06Cr13 stainless steel pipe. In this paper, 06Cr13 stainless steel performance, materials and their welding performance starting 06Cr13 stainless steel pipe welding technology and its requirements to ensure that the high-pressure gathering pipe 06Cr13 steel pipe welding performance indicators to meet the design requirements to ensure the normal operation of high-pressure gathering pipelines later.
