摘要:
针对川渝地区页岩气开采过程中出现的套损问题,设计开发了BSG-125TT SEW高抗挤套管,并对其力学性能、微观组织、抗挤毁性能进行了分析。结果显示,在910 ℃淬火+580 ℃回火热处理条件下,BSG-125TT 钢级SEW高抗挤套管的屈服强度为960 MPa,抗拉强度为1 020 MPa,母材横向冲击功为126 J,焊缝横向冲击功为105 J,焊缝与母材组织及性能基本一致。研究表明,BSG-125TT SEW高抗挤套管具备高强韧性匹配及优异的综合性能,满足页岩气特殊工况开发的需求,为油气田开采选用合理套管提供了装备技术支撑。
Abstract:
In view of casing damage in shale gas exploitation in Sichuan-Chongqing area, BSG-125TT SEW high collapse resistant casing was designed and developed, and its mechanical properties, microstructure and collapse resistant property were analyzed. The results show that under the conditions of 910 ℃ quenching + 580 ℃ tempering heat treatment, the yield strength of BSG-125TT steel grade SEW high collapse resistant casing is 960 MPa, the tensile strength is 1 020 MPa, the transverse impact energy of base metal is 126 J, and the transverse impact energy of weld is 105 J, so as to achieve the goal of basically consistent microstructure and properties between weld and base metal. Research shows that BSG-125TT SEW high collapse resistant casing has high strength toughness matching and excellent comprehensive performance, meets the needs of shale gas development under special working conditions, and provides equipment and technical support for selecting reasonable casing for oil and gas field production.
