The thread lubricant and sealant for deepwater and ultra-deepwater oil and gas fields needs to maintain sealing and lubrication performance under extreme conditions such as high pressure, high temperature, corrosive media (such as salt water, H₂S, CO₂), long-term static standing, etc. Its technical requirements mainly cover the following aspects:
Core performance requirements
Wide temperature range: Adapt to the wide temperature range of deepwater wellbores from seabed low temperature (about 2–4℃) to formation high temperature (up to 150–260℃), with typical working temperature ranging from -30℃ to +260℃.
High-pressure sealing performance: Not be squeezed out or washed away under a pressure difference of 140–200 MPa, effectively filling the microscopic gaps of the threads and preventing high-pressure fluid leakage.
Corrosion resistance and anti-sulfide stress corrosion: Need to withstand the erosion of H₂S, CO₂, chloride ions and acidic condensate, in accordance with NACE MR0175/ISO 15156 standards, to prevent hydrogen embrittlement, pitting and sulfide stress cracking.
Extreme pressure anti-wear and anti-sticking: Contains solid lubricants (such as graphite, molybdenum disulfide, PTFE or self-healing particles), preventing thread abrasion, biting and other phenomena during makeup/breakout under high torque.
Typical application scenarios compatibility
Deepwater/ultra-deep well oil and casing connection: Bearing alternating stress, vibration and long-term static load
High-temperature high-pressure (HPHT) wells: Such as thermal recovery injection wells, supercritical steam wells
Sulfur-containing gas wells: Need to balance sealing and corrosion resistance functions
Offshore platform operations: Requiring long-term maintenance-free and “lifelong sealing” capabilities.
