SCA2003-57: EFFECTIVENESS OF A COMPLEX APPROACH TOWARDS THE STUDY OF THE WEST SIBERIA PUKURIAN SUITE RESERVOIRS PRESENTED BY POORLY CEMENTED ROCKS

摘要

Only in the late 90-s a comprehensive solution for estimation of petrophysical parameters of the Pokuria n suite poorly cemented reservoirs was suggested and realized in the Severo-Komsolskoye and Samotlor oil fields.The coring was run using the native-state core recovery method with placement of cores into the plastic inner core barrels and the core preparation for analysis was carried out by freezing it in liquid.The complex analysis of the cut core and core samples allowed to recognize a thin-laminated structure of the formation PK-1 in the field Severo-Komsomolskoye and to justify petrophysical relations for estimation of porosity,permeability and gas saturation of poorly cemented reservoirs.
