Purpose<\/em><\/strong><\/p>\n\n\n\n

New advanced technology of cavitation pulse stimulation of oil wells 3 to 4 km in depth for well yield increase and well recovery.<\/p>\n\n\n\n

The essence of the technology<\/em><\/strong><\/p>\n\n\n\n

The technology is based on generating high-frequency hydraulic pressure pulses in the well at the productive stratum level. The hydraulic pressure pulses have a frequency of 1,000 to 6,000 Hz and an amplitude up to 60 MPa. The hydraulic pressure pulses are generated at the outlet of the hydrodynamic device inserted into the well.<\/p>\n\n\n\n

Advantages<\/em><\/strong><\/p>\n\n\n\n

The new, unique distinction from world analogs is the use of a proprietary high-frequency pressure pulse generator without any moving or rotating parts. The high-frequency, high-amplitude pressure pulses are generated in the well using the stream energy of the fluid fed to the generator. The technology will offer a 3- to 5-fold increase in well yield.<\/p>\n\n\n\n

Operational testing<\/em><\/strong><\/p>\n\n\n\n

Pressure pulse treatment of oil wells has been conducted. The results have shown that relatively short stratum stimulation times (60 to 120 min) suffice to obtain a 3.0- to 3.5-fold increase in well yield.<\/p>\n\n\n\n

Possible users<\/em><\/strong><\/p>\n\n\n\n

Service and drilling companies in different countries.<\/p>\n\n\n\n
