Zderka T. Lithogenetic fracturing and its influence on containing oil of breeds-collectors (on the example of oligocen deposits of Nadvirna petroleum industrial district)

Object of research - Oligocene deposits of Nadvirna oil and gas industrial district; the purpose of research - establishment of terms and conformities to law of forming of lithogenetic fracturing and its influence on containing oil of oligocene reservoires of Nadvirna oil and gas industrial district and their lauter-capacity properties; research receptions - complex microscopic researches of breeds-collectors in microsections, statistical treatment of the got results, geologo-statistical designs and graphic constructions, system analytical method of treatment geologo-industrial information; theoretical and practical results - it is set that lithogenetic cracks influence on forming lauter-capacity properties of oligocene breeds-collectors, it is found out for the first time the conformities to law of distribution and the geological model of forming of lithogenetic fracturing is developed within the limits of local oil an gas objects; the novelty entered - it is suggested to conduct opening of layers with the porous-fracturing type of reservoir and treatment of near well area with the use of the proper solvents with the purpose of washing heavy hydrocarbon components from lithogenetic cracks and fixing them with a quartz sand which will increase the waves of oil to the mining holes; the degree of introduction - it is inculcated on Pivdenno-Gvizd deposit; sphere (area) of use - production and research geological survey organizations.
