Fedak I. Methodological and experimental basis of the irrigation of oil and gas fields process evaluation on the results of geophysical exploration (on the example of Semenivske oil field)

Research object - lower-miocene productive deposits of Semenivske oil field; a research purpose is development of methodical bases of the use of geophysical information for the construction of the detailed of geological filtration model, adapted to the existent geological terms of deposit, with the purpose of prognostication of outstrip irrigation of productive layers-collectors. Creation of methodical bases for the selection of go to water intervals of productive layers from data of geophysical researches of mining holes in difficult industrially geological terms; research methods are statistical treatment of results of laboratory researches of core and geophysical borehole logging of productive intervals; analysis of theoretical and experimental models of petrophysical descriptions of productive complexes; geophysical researches in a mining hole by the method of thermoactive well logging; theoretical and practical results - the detailed of geological filtration model of Semenivske oil field is built on the basis of results of geophysical borehole logging, which is basis for conducting of control and prognostication of irrigation of productive horizons; the methods of selection of go to water productive layers-collectors are offered with the use of radon indicator and thermoactive well logging methods in the conditions of fresh layer waters and high-density oil, which will do possible conducting of effective control after the process of irrigation of deposit; novelty of the got results - a sediment-logging analysis enabled to conduct classification of curves of gamma ray logging after their form and create the charts of distributing of areas with the different dynamics of distribution of small dispersive faction, where lithologycal heterogeneities of productive packs of Semenivskе oil field are localized; the rationed parameter of go to water clay faction of breeds-collectors of lower-miocene deposits of Semenivske oil field is offered enabled to conduct their authentication, and the use of this set connection with the thickness of tape of the linked water resulted a parameter in the improvement of method of determination of coefficients of permeability of mountain breeds during the design of them filtration properties.
