On the possibility of wave action application in combination with methods improving bottomhole formation zone permeability

E.S. Abdullayeva

The paper considers the possibility of application of vibration wave method on bottomhole formation zone in sand wells. For cleaning of well bottomhole from sand and mechanical mixtures via transformation of energy of technological liquid injected in well into the hydrodynamic impulses, using of well generator differing with simplicity of construction, high reliability and efficiency is recommended. Offered generator of hydrodynamic fluctuation may be applied either in the combination with various methods of sand control, or separately for regulation of pressure drawdown. Field tests of developed well generator were carried out in three wells of “Neft Dashlary” OGPB. The results of field tests confirmed high reliability of well generator of hydrodynamic fluctuations and prospects of further widespread application of the device.
