Hydrodynamic Relation

For the implementation of shock-wave treatment on bottomhole zone of formation, there are various devices not providing efficient resonant shakedown of borehole fluid column creating shock waves of pressure and vacuum, which is not efficiently productive and reliable as well. To reduce filtration resistances and reset hydrodynamic relation of the reservoir and well, a new construction of wellhead device for shock-wave treatment on bottomhole zone, which may be used for increasing oil recovery rate via the effect through the well on Productive Series during completion and repair of producing well, has been developed. By developing a reliable and constant pressed airflow with low pressure, the paper solves the task of increasing the frequency of closing and opening of wellhead device, enabling to use it for creating shocking waves of pressure and vacuum in the well. The implementation of developed device improving hydrodynamic relations and hereby, simplifying filtration in the “reservoir-well” system, puts in production low permeable and isolated zones of Productive Series, which promotes the oil recovery rate increase and reduce oil prime cost as well.
