METHOD OF PRODUCING FORMATION STIMULATION

摘要

FIELD: oil producing industry. SUBSTANCE: method includes selection of section, installation of elastic vibration source with dynamic load of 100-500kN acting from side of day surface and exciting elastic waves on selected section. Section is selected by measuring of microseismic background on investigated area by seismometers. Selected for installation of elastic vibration source is section with high level of microseismic background. Maximum background level is considered such level which differs from background level on other sections by maximum values of amplitude of registered signal corresponding to any one frequency, or, with maximum integral characteristic of all registered frequencies. Microseismic background is measured and analyzed before experimental stimulation, and/or during this stimulation, and/or after it before determination of dominant frequencies. Dominant frequencies are considered those which are distinguished among common spectrum of frequencies by maximum level of registered signal. Producing formation is stimulated by elastic waves on dominant frequencies. EFFECT: higher efficiency of oil production process. 3 cl
