Influence of geological reservoir characteristics and technical performance of the equipment on wells

In this work considered geological and technological factors that substantially affect on the operational wells work. So, the bottomhole pressure influence on operating efficiency of production wells was studied.The correlation between electric resistances of oil layer and value of wettability of terrigenous collectors was established. In addition, for terrigenous objects, for the fields considered in article, the interrelation between the increased values of electric resistance and deterioration in the accepting ability of delivery wells is revealed. The study shown that correctly picked up operational equipment on production wells allows to receive optimum outputs. In article offered use the information about electric resistance value for determination of hydrophobic collectors’ development zones before making decision of development of fields.
Materials and methods
For study was executed gathering and data processing of the lateral logging on 634 wells of Upper Prikamye fields, were unloaded from the information system "BaseGis" with formationof appointed formats, suitable for loading to program complex IRAP RMS of ROXAR company, which was used for creation of the three-dimensional array of electric resistance distribution.
Results
Authors have studied and proved in practice the defining influence of geological parameters of the layers and technical characteristics on the equipment, on operation of producing oil wells and injection wells. Calculations performed on the simulation model, showed increase in oil production due to planned activities on the discharge wellstock and 100% liquid injection compensation selections.
Сonclusions
The received results allow to optimize technological design of new perspective deposits and developed pool. Obtained conclusions about the correlation of various characteristics are recommended for use in production not only the Upper Kama region, but also in other fields of the Perm Prikamye.
