Abstract

The prospects for further increase in oil production determined the introduction of new advanced technologies at all stages of the geological exploration process, drilling of wells, extraction and processing of hydrocarbons. On exploited deposits located at the late and final stages of development, in areas with developed infrastructure, the task of increasing oil recovery is particularly relevant. The increase in the total oil extraction in the fields by only a few percent allows us to obtain additionally millions of tons of oil and gas condensate. The oil reservoir is a multifactorial dynamic dissipative system and possesses all the properties of nonlinear self-organizing systems. To order the physicochemical processes in the formation in the parametric resonance mode, it is sufficient to periodically apply pressure to the formation by wide-band pulses from an independent nonlinear source. Such an independent well source is a plasma-pulse generator with an energy of about one kilojoule and a frequency spectrum from a few hertz to several kilohertz with a period of elastic vibrations 1-2 times per minute. The authors of the proposed technology suggest using an underwater electric explosion of conductors, in which the process of formation of a conducting channel is a successive chain of phase transformations of a metal under the influence of a pulsed current and then a breakdown of the hydromedia along the products of the explosion. A typical process of initiating a discharge is the breakdown of the interelectrode gap in a liquid under the influence of an electrical voltage that appears on the electrodes when a charged capacitor is connected to them through a conductor initiating an explosion. The application of the plasma-pulse effect equipment on the productive reservoir ensures an increase of oil and gas production rate and injectivity of injection wells by a factor of 2-6 and an improvement in the oil-water ratio of the produced fluid.
