Abstract: Oil and gas development has strict requirements for the seal ability of premium threaded connections (PTCs) of tubing. Assessing the seal ability of joints can help reduce the risk of leakage after running the string. Using ...

Abstract: The first-stage absorber, which is often used to purify crude oil or highly acidic natural gas, is the core equipment of petrochemical enterprises. Uniaxial strength is checked considering axial stress, hoop stress, and ...

Abstract: With the development of drilling technology and reinforced exploration and exploitation of unconventional reservoirs, there has been a great increase of complex wells. Meanwhile, however, consequent casing wear is and will ...

Abstract: According to the tubing string failure statistics in the oilfield, fatigue crack of tubing joint thread in high temperature high pressure (HTHP) ultradeep gas wells remains a problem because it can cause tubing strength ...
