FIELD: oil and gas geology, possible use for optimizing positioning of surveying and product wells at oil-gas objects.
SUBSTANCE: in accordance to method for determining filtration-capacity properties and predicted oil-gas productiveness of collectors in three-dimensional inter-well space, on basis of seismic, gravimetric, magnetic, electric and geo-informational system attributes of various physical nature, received data are transformed by means of spectral decomposition onto multi-channel spectral-temporal columns. Multi-dimensional mutual correlation dependencies are determined between spectral-temporal columns. Unified information array is formed, connected to drilling data. Aforementioned array is transformed to structural-tectonic, lithologic-facial, filtration-capacitive, oil-gas-productive geological models in form of cuts, maps and cubes. Oil-gas objects are detected with consideration of received models on basis of increased values of specific capacity and hydro-conductivity of collectors and also oil-gas-productiveness coefficients.
EFFECT: increased reliability of detection of oil-gas objects, more justified geological conditions for founding surveying and product wells.
