Abstract

FIELD: oil and gas producing industry. SUBSTANCE: device for treatment of bottom-hole formation zones and well completion has some hydrodynamic pump operating due to supply of working fluid and differential controlled valve operating on the basis of certain pressure differential occurred in zone of supply of working fluid and zone under packer. In this case, in the course of device operation, hydrodynamic hammer is produced in the zone under packer to effectively act on the bottom-hole formation zone. Treatment of well is automatically discontinued after restoration of its hydrodynamic characteristics. EFFECT: higher efficiency.

Claims (1)

Устройство содержит какой-либо гидродинамический насос, работающий от подачи рабочей жидкости и дифференциальный регулируемый клапан, работающий от определенного перепада давления, образованного в зоне подачи рабочей жидкости и подпакерной зоне. При этом в процессе работы устройства в подпакерной зоне создаются гидродинамические удары, способствующие эффективному воздействию на призабойную зону пласта. Процесс обработки скважин автоматически прекращается после восстановления ее гидродинамических характеристик.
Figure 00000001
The device contains some kind of hydrodynamic pump, working from the supply of the working fluid and a differential adjustable valve, working from a certain pressure drop formed in the zone of supply of the working fluid and the under-packer zone. Moreover, during the operation of the device, hydrodynamic shocks are created in the sub-packer zone, which contribute to the effective impact on the bottomhole formation zone. The well treatment process automatically stops after the restoration of its hydrodynamic characteristics.
