Price: Inquiry
Key words: Composite cross-linking plugging agent gel particles PEG-1
Description: The PEG developed and produced by Hongdali has high economic benefits, reduces the cost of the enterprise, and has good scalability and extensibility in specific use.

Detailed Description

  based on several oil-reservoirs are characterized by strong heterogeneity, prominent cross-section contradiction, developed micro fractures, multi-directional water breakthrough in oil wells, rapid water cut rise, difficult treatment and low productivity recovery rate. In order to improve the injection profile, control the dominant water drive channel, and realize the goal of stable water control in the well group, the company has actively developed and produced PEG-1 composite cross-linked plugging agent. The purpose is to form a physical barrier, plug micro fractures, high permeability zone and other water drive advantageous channels, effectively balance water drive, expand water drive swept volume, and improve reservoir development effect.


 The characteristics of the PEG-1 series products developed and produced by Hongdali:

  1. The product  has one important characteristic as certain mobility,which is helpful to expand the scope of water regulation and improve the effect of water blocking;

  2. The granular gel ground cross-linking product solves the problem of non-gel formation caused by various complex reasons such as dilution, degradation, adsorption, etc. after the conventional underground cross-linking water blocking agent enters the formation;

  3. It has good selective entry conditions, which is helpful to reduce the damage of profile control agent to non-target layer. The particle plugging agent can be properly selected to form a surface blockage in the non-target oil-producing layer and smoothly enter the large pores of the water drive, so as to achieve the purpose of the water plugging agent selectively entering the sealing layer;

  4. According to the actual conditions of the construction site, the particles with appropriate expansion ratio and strength can be selected first.


  According to the parameters obtained from the field experiment:
