Abstract:

The paper presents the process of formation of oil well’s annularcement, the nature of the phenomenon of the pressure between casings, some of the methods and results of well annular survey has carried out at Vietsovpetro. Some results of aerohydrodynamic survey combined with safety rules for wells having pressure between casing in separated time in over 20 years show that there is considerable variation of parameters in well's annular. These results have great significance for production activities, help Vietsovpetro having a scientific basis to safely operate the wells with sign of pressure between casings.
