To the question of the study of a vibration device to eliminate seizures during the construction of oil and gas wells

Abstract

The drilling process is one of the most expensive steps in the construction of an oil well. Therefore, methods that reduce drilling costs without compromising the quality of well construction are always in demand by oil companies. As a rule, specialists in the field of drilling seek to increase the rate of penetration, reduce the number of round trips, eliminate accidents due to tool breaks, ensure uniform weight on bit, reduce time spent on eliminating complications, etc. Among these approaches, a special place is occupied by the technology of using vibration devices to prevent sticking of the drill string. The article presents theoretical studies of the operation of the device for dynamic impact on the bottomhole, allowing to assess the influence of design factors on its operation. The performed studies allow us to recommend the use of the device in a single bottomhole assembly to create pulsating flushing and dynamic loading of the bit. The obtained research results can be used in the design of downhole assemblies of various sizes with hydraulic vibrators for drilling wells.
