Making up and breaking out tests,thermal cycle gas-tight tests,internal pressure and tension tests under bending condition,tension to failure tests,and internal pressure to failure tests were carried out to139.7mm×7.72 mm J55low pressure gas-tight casing joint samples.The results show that the anti-gluing property of the joints was good,the sealing capability was qualified both under the condition of the temperature of135 ℃ and the pressure of 35 MPa and under the condition of the pressure of 30 MPa,the bending dogleg angle of10°/(30m)and the tension load of 80% nominal yield strength.The leakage failure internal pressure and the tension strength of the joints were all much higher than those of the standard technical requirements.
