ACOUSTIC METHOD AND DEVICE FOR FACILITATION OF OIL AND GAS EXTRACTING PROCESSES

摘要

A method for improving and maintaining well productivity is disclosed. The method comprises placing at least two acoustic devices within key wells of a geological formation, measuring parameters for initial acoustic impact, and continuing to measure parameters in order to change impact parameters during production and optimize the acoustic effect. The method may be used to restore, maintain, or increase the productivity of an entire geological formation (oil or gas), and to reduce the water cut in the formation.

1. A method for restoring, maintaining, or increasing oil or as productivity of a geological formation or reducing a water cut in the formation, comprising: positioning at least two electrical acoustic devices, each within a different key well of a hydrodynamically connected system located within the geological formation, and performing an acoustic treatment within each key well by said at least two acoustic devices, sending acoustic waves from each device via liquid medium in the hydrodynamically connected system, thus causing a destructive acoustic impact on the entire geological formation; measuring formation parameters during the acoustic treatment, and optimizing at least one functioning parameter of the acoustic devices based on the measured formation parameters; wherein the acoustic treatment is automatically controlled by microcontrollers mounted on the acoustic devices; and restoring, maintaining, or increasing oil or gas productivity of a geological formation or reducing a water cut in the formation due to the acoustic impact.
