Research and Development of High Temperature Production Sliding Sleeve
A suitable high temperature production sliding sleeve was designed for offshore well completion,its rated temperature and rated pressure are 180℃and 35MPa respectively.On the basis of theoretical calculation and finite element analysis,the locking performance of cantilever beam type and clamped beam type locking claw were studied,the max locking force of cantilever beam type and clamped beam type locking claw by theoretical method were 545N and 2853N respectively,the max locking force of cantilever beam type and clamped beam type locking claw by finite element method were 421N and 2443N respectively.Testing method was adopt as verification,the max locking force of cantilever beam type and clamped beam type locking claw were 434N and 2193N respectively,the studies show that finite element analysis values are closer to the testing values.At last,the high temperature sealing property was tested,the production sliding sleeve meets the design requirements.
