Drill pipe and oil casing pipe connection method

The connection method of drill pipe and oil casing pipe mainly relies on specific joints and threaded connection technology to ensure safety and efficiency during the oil drilling process. ‌These connection methods include but are not limited to:‌

1. Threaded connection

‌Drill pipe and oil casing pipe are connected through specific threads, ‌these threads are designed to withstand high pressure and high torque, ‌ensuring stability and safety during the drilling process. ‌Common thread connection types include API threads, ‌STC, ‌LTC, ‌BTC, etc. ‌These thread types are suitable for pipes of different sizes and pressure levels, ‌meet the needs of various drilling conditions. ‌

2. Special buckle processing
‌For special application scenarios,‌ special buckle processing may be required,‌ such as DS55 buckle, ‌special buckle processing, etc.,‌to meet specific drilling needs. ‌This processing can be carried out according to order requirements, ‌ensuring a precise connection between drill pipe and oil casing. ‌

3. Variable buckle conversion connector
‌During the drilling process,‌ depending on different drilling depths and geological conditions,‌it may be necessary to use different sizes or types of drill pipes and oil casings. ‌Variable adapters are used to connect drill pipes and oil casing of different sizes or types to ensure the continuity and efficiency of drilling operations. ‌

4. Casing drilling technology
‌In casing drilling technology,‌ the casing is not only used to support the well wall,‌but also applies torque and bit pressure to the drill bit through a specific connection method,‌to realize the rotation and drilling of the drill bit. ‌This technology reduces the frequency of tripping, ‌reduces drilling costs, and ‌improves drilling safety. ‌

To sum up, there are various connection methods for drill pipe and oil casing pipe, including threaded connection, special buckle processing, variable buckle conversion joint, etc. The choice of these connection methods depends on the specific drilling conditions and needs. To ensure the safety and efficiency of drilling operations. ‌
