Abstract

Abstract:

In this article, experimental investigation of the flowing gelling time and transferprocess of crosslinked polymer solution has been conducted in porousmedium with a long sand packing model.The flowing gelling time has been ascertained and the transfer process in porousmedium has been considered. Results indicate that the dynamic gelling time ismore than the static gellin time and the dynamic gelling time is 9-11 days in the experimental condition. The propagation property of the crosslinke polymer solution is excellent by the transfer process experimen in porousmedium.

Key words: crosslinked polymer solution, polyacrylamide, porousmedium, dynamic gelling time, propagation
