Abstract

1415982 Boring earth &c KOOLAJ ES FOLDGAZBANYASZATI IPARI KUTATO LABORATORIUM 28 Aug 1973 4876/75 Addition to 1415981 Heading E1F A method of drilling and/or formation treatment in underground strata comprises applying to a flushing mud flowing through a drilling tool 2 an ultrasonic frequency. When drilling, the frequency is preferably equal to, or a multiple of, the natural frequency of the tool. When treating a formation after casing and perforation, for increasing permeability, the ultrasonic waves are directed generally parallel with the direction of the formation, and the frequency is equal to, or a multiple of, the local natural frequency of the formation. The desired ultrasonic frequency is obtained by selecting a cavity resonator 5 of a particular dimension and connecting it to an exciting element 4.
