Common failures of drill pipe joints include the following:
May be caused by excessive wear, collision, etc.
Causes leakage of drilling fluid.
Fatigue fracture: caused by prolonged use or excessive force.
Influenced by drilling fluids, corrosive media, etc. 5.
Affects the stability and safety of the drill pipe.
May occur during drilling.
Reduces the strength and performance of the joint. 8.
May cause serious problems such as fracture.
Loss of sealing effect.
Affects the connection and disassembly of the drill pipe.
These failures may affect the normal use of drill pipe joints and even lead to interruption of drilling operations or safety accidents. In order to minimize the occurrence of failures, regular inspection, maintenance and servicing are required. The following are some suggestions:
1. check the condition of threads regularly and repair or replace damaged threads in time.
2. Pay attention to the maintenance of seals and replace them regularly.
3. avoid overuse and overload to prevent fatigue fracture.
4. take anti-corrosion measures to reduce the effects of corrosion.
5. install and dismantle the drill pipe joints correctly and avoid forced operation.
6. carry out flaw detection on drill pipe joints and deal with cracks in time.
