Abstract

This paper presents the results of the study of sedimentation stability of polymer-dispersed systems (PDS) based on acrylamide and chemical industry waste, developed to regulate filtration flows in heterogeneous terrigenous reservoirs and increase waterflood coverage ratio. The aim of the work is to determine the most stable polymer-disperse system in time. Within the framework of the experiments the following tasks were performed: conversion of technogenic waste into non-toxic form and grinding to powdery state; preparation of aqueous solutions of acrylic polymers of different molecular weights and ionic charges; visual control of the prepared polymer-disperse systems during 24 hours by video recording; analysis of the obtained results. From the experimental results, it was found that polymer-dispersed systems based on anionic polymers with higher molecular weight have the highest sedimentation stability. However, the solution based on DP-9 polymer with high molecular weight is not sedimentation stable. Thus, the sedimentation stability depends on the set of properties of the polymer used, namely its molecular weight, type and charge density of molecules.

Key words:

sedimentation stability, polymer solution, conformance factor, regulation of filtration flows, residual reserves, non-Newtonian fluid, catalytic slurry
