Khudin M. Improvement of technical devices of pulse-wave action on the oil and gas saturated layers

The thesis is devoted to the study and improvement of pulse-wave action devices on the oil and gas saturated layers. Justified the development and new design of hydraulic generator pulse-wave impact on oil and gas saturated layers was proposed. As the result of processes simulation occurring in the generator when it is operating, the dependence of the total sound resistance in generator with the holes on the values of its structural and mechanical parameters was developed. An experimental setup for studying the performance of the generator in case of changing physical parameters of its work items was developed. The method of the directly generator research in the well and when exposed to formation using the layer simulator was developed. The acoustic pressure, temperature and hydraulic vibration during generator operation was obtained, the dependences describing the variation of these parameters. Obtained analytical dependence of the frequency and amplitude of the pulse generator on its physical parameters (length and weight of the valve rod) was obtained. Calculations by the developed analytical dependences have a high correlation degree with the experimental results (more than 0.85). The new design of hydraulic pulse-wave action generator on the oil and gas saturated layers has been successfully pilot-scale tested on wells Yaksmanitsa-33, 8-Staryj Sambir, 1-Semakivska and others as well development and the intensification of the hydrocarbons production.
