适用于致密气藏钻完井的新型超级13Cr油钻杆管材性能测试
Performance test of a new super 13Cr oil drill pipe used for tight gas reservoir drilling and complication
摘要
Abstract
A new high strength super 13Cr oil drill pipe was developed for tight gas reservoir exploitation in Tarim oilfield .This paper studies the tensile property and impact property of S135 dirll pipe and new super 13Cr oil drill pipe by a material tensile testing machine and a instrumen-ted impact testing machine respectively .Their corrosion resistance to CO2 is also studied through high temperature and high pressure autoclave test .The results show that the ultimate strength of the new super 13Cr steel reaches 976 MPa ,with the yielding strength 937 MPa and elongation 19 .0% .Its impact energy reaches 162 .82 J .Compared with S135 steel ,the new super 13Cr steel has similar strength property and better impact property .Under the test condition ,the corrosion rate of the super 13Cr steel is 0 .003 6 mm/a in gas phase and 0 .039 4 mm/a in liquid phase . Therefore ,the new super 13Cr oil drill pipe can meet the requirement of drilling and well compli-cation .The new oil drill pipe could provide support for tight gas reservoir nitrogen drilling and well complication .关键词
