Modeling of the fluid filtration to a well, equipped with the vertical slot filters

Abstract

To ensure the necessary flow rates of wells equipped with an anti-sand filter, it is necessary to evaluate the throughput of the filter. In this paper we are considering one of its most common designs – a vertical-slotted filter. For the case of a single slot periodically repeating over the pipe, an expression for the determination of the skin factor was obtained by V.P. Pilatovsky. In order to identify the best filtering scheme for the arrangement of the slots in the vertical-slit filter, in this work a universal dependence for determining the value of the additional filtering resistance that appears in the bottomhole zone of the well has been considered.
