摘要
采用往复式摩擦磨损试验机对13Cr-L80钢油管和套管进行往复磨损试验,研究了接触载荷(50,100,150,200,250 N)、往复行程(2,4,6,8,10 mm)、往复频率(0.6,0.9,1.2,1.5,1.8 Hz)以及完井液密度(1.0,1.1,1.2,1.3,1.4 g·cm^(-3))对油管磨损性能的影响。结果表明:随着接触载荷、往复频率和往复行程的增加,油管的磨损量增大,摩擦因数和磨损率变化不大;随着完井液密度的增加,磨损量和磨损率均降低,摩擦因数先降低,当完井液密度增大到1.2 g·cm^(-3)时趋于稳定;在试验条件下,随接触载荷、往复频率及完井液密度的增加,油管的磨损方式均由磨粒磨损转变为黏着磨损,不同往复行程下油管的磨损方式均为黏着磨损。
The reciprocating wear test of 13 Cr-L80 steel tubing and casing was carried out with a reciprocating friction and wear testing machine.The effects of contact load(50,100,150,200,250 N),reciprocating stroke(2,4,6,8,10 mm),reciprocating frequency(0.6,0.9,1.2,1.51.8 Hz)and completion fluid density(1.0,1.1,1.2,1.3,1.4 g·cm^(-3))on the wear performance of the tubing were studied.The results show that with increasing contact load,reciprocating frequency and reciprocating stroke,the wear amount of the tubing increased,and the friction factor and wear rate changed little.With increasing completion fluid density,the wear amount and wear rate of the tubing decreased,and the friction factor decreased first,and then tended to be stable when the completion fluid density increased to 1.2 g·cm^(-3).Under testing conditions,with increasing contact load,reciprocating frequency and completion fluid density,the wear mode of the tubing changed from the abrasive wear to the adhesive wear,and the wear modes of the tubing under different reciprocating stroke were all adhesive wear.
