It were revealed destruction sources of the thread of oilfield and drilling equipment in complicated conditions and made analysisof that sources. Deep roll thread method was considered to increase its durability.
Materials and methods
Methods of mathematical statistics are used.
Results
The problem definition of hardening of bottom of thread was made, numbers of numerical experiments were carried out and residual stresses were determined.
Сonclusions
1. Bounce statistics the drilling and oilfield equipment was reviewed.
2. The main causes leading to the accident on the oil well were revealed.
3. Provided recommendations for using the running-thread roll thread to increase reliability.
