Abstract
1. Способ генерирования волн давления на забое скважины, при котором устанавливают на нижнем конце насосно-компрессорной трубы (НКТ) струйный генератор Гельмгольца (СГГ), представляющий собой колебательную систему, возбуждаемую струёй протекающей через неё жидкости и состоящую из струйного генератора, расположенного внутри камеры объёмного резонатора, при этом генерируют струйным генератором первичные колебания давления определённой частоты в струе жидкости и возбуждают ими колебательную систему, усиливают первичные колебания давления в камере объёмного резонатора, частоту собственных колебаний которого настраивают в резонанс с частотой генерации первичных колебаний давления, и создают волны давления на забое скважины, отличающийся тем, что устанавливают за камерой объёмного резонатора ещё одну камеру с отверстием и формируют, таким образом, колебательную систему, имеющую три частоты собственных колебаний, не соответствующих частотам собственных колебаний её отдельных элементов, настраивают частоту генерации первичных колебаний давления на высшую частоту собственных колебаний колебательной системы, при этом возбуждают колебательную систему на всех остальных собственных частотах и генерируют колебания давления на низшей частоте собственных колебаний.2. Устройство для генерирования волн давления на забое скважины, разработанное на базе струйного генератора Гельмгольца (СГГ) и установленное на нижнем конце канала насосно-компрессорной трубы (НКТ), состоящее из камеры объёмного резонатора с двумя параллельными крышками, внутри которой расположен струйный генератор, состоящий из входного сопла,1. A method of generating pressure waves at the bottom of a well, in which a Helmholtz jet generator (SGH) is installed at the lower end of the tubing, which is an oscillating system excited by a jet of fluid flowing through it and consisting of a jet generator located inside the chamber of a volume resonator, in this case, primary oscillations of pressure of a certain frequency in the liquid stream are generated by a jet generator and excite an oscillating system by them, amplify primary oscillations in the chamber of the cavity resonator, the natural frequency of which is tuned to resonance with the frequency of generation of the primary pressure oscillations, and create pressure waves at the bottom of the well, characterized in that they install another chamber with a hole behind the chamber of the cavity resonator and thus form an oscillatory system having three frequencies of natural oscillations that do not correspond to the frequencies of natural oscillations of its individual elements, adjust the frequency of generation of the primary pressure oscillations to a higher frequency spontaneous vibrations of the oscillatory system, in this case they excite the oscillatory system at all other natural frequencies and generate pressure oscillations at the lowest natural frequency. 2. A device for generating pressure waves at the bottom of the well, developed on the basis of the Helmholtz jet generator (SGH) and installed on the lower end of the channel of the tubing, consisting of a cavity resonator chamber with two parallel covers, inside of which there is a jet generator, consisting of inlet nozzle
