Step-Growth Polymerization: Overview

3.6K
Step-growth or condensation polymerization is a stepwise reaction of bi or multifunctional monomers to form long-chain polymers. As all the monomers are reactive, most of the monomers are consumed at the early stages of the reaction to form small chains of reactive oligomers, which then combine to form long polymer chains in the late stages. Hence, the reaction has to proceed for a long time to achieve high molecular weight polymers.
Many natural and synthetic polymers are produced by...

Anionic Chain-Growth Polymerization: Overview

2.1K
The polymerization process that involves carbanion as an intermediate is called anionic polymerization. It is also a type of addition or chain-growth polymerization. Anionic polymerization gets initiated by a strong nucleophile such as an organolithium or a Grignard reagent. The most commonly used initiator for anionic polymerization is butyl lithium. Monomers involved in anionic polymerization must possess a vinyl group bonded to one or two electron-withdrawing groups. For instance,...

Summary

Polymer flooding shows promise, but high-concentration, high-molecular-weight (HCHMW) polymer use is limited due to unclear mechanisms. This review clarifies polymer flooding, discusses viscoelasticity effects on residual oil saturation, and summarizes Chinese field tests, including salt-resistance polymers (SRPs).

Area of Science:

  • Petroleum Engineering
  • Enhanced Oil Recovery
  • Polymer Science

Background:

  • Polymer flooding is a mature enhanced oil recovery (EOR) technique, with significant applications in China's Daqing oilfield.
  • Laboratory studies suggest polymer viscoelasticity enhances displacement efficiency and reduces residual oil saturation (ROS).
  • Discrepancies exist between laboratory findings and recent field test results regarding high-concentration, high-molecular-weight (HCHMW) polymer effectiveness.

Purpose of the Study:

  • To systematically summarize polymer flooding mechanisms and field applications in China.
  • To critically review the viscoelasticity effect of polymers on ROS reduction.
  • To clarify the reasons behind the limited application of HCHMW polymers despite promising laboratory results.

Main Methods:

  • Critical review of existing literature on polymer flooding mechanisms and viscoelasticity effects.
  • Analysis of laboratory core flooding data and field test results from China.
  • Discussion of alternative polymer flooding mechanisms, including wettability alteration and gravity stability.

Main Results:

  • HCHMW polymer application is limited due to a lack of understanding of polymer flooding mechanisms and potential reservoir issues.
  • Salt-resistance polymers (SRPs) utilizing produced water show economic and environmental promise.
  • Formation blockage and injectivity issues have been reported due to misinterpretations of polymer behavior.

Conclusions:

  • The effectiveness of polymer flooding depends on a nuanced understanding of polymer properties and reservoir interactions.
  • HCHMW polymer injection is not recommended for medium-to-high viscosity oils, especially in older wells.
  • Further research and careful implementation are needed to optimize polymer flooding strategies, including the use of SRPs.
