In the article were identified the main causes of failure of oilfield and drilling equipment in complicated conditions and executed their analysis. An efficient method of deep roll thread to increase durability of the products was proposed.
Materials and methods
Methods of mathematical statistics are used.
Results
The problem definition of hardening of thread bottom was made, numbers of numerical experiments were carried out and residual stresses were determined. Developed the program of predicting residual stresses.
onclusions
1. Bounce statistics the drilling and oilfield equipment was revealed.
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.
