Factory anion flocculant polyacrylamide for oil drilling chemicals

Specifications

1)Easy to dissolve
2)High efficient, high viscosity
3)Fully in line with world standard

           

The high molecular weight Anion Flocculant Polyacrylamide produced by our company for EOR applications are manufactured by the partial hydrolysis of acrylamide. The process can be pre-hydrolysis or post-hydrolysis. Our company chooses the process to make the products depending on the application. The following table shows the specifications of our products.

Main Applications:

1. Polymer flooding: Generally, when an oilfield is in the alter stages of water drive, the higher mobility of water relative to oil in situ causes the coverage of the driving water to be greatly reduced. The heterogeneity of the oil reservoir can also lower the coverage of the water drive. Thus, water consumption will increase, and water cut in the produced fluids can become prohibitive and a lot of oil is left untouched. If polyacrylamide is added to the water as a thickener the mobility ratio is improved, the sweep efficiency is improved to reduce the water cut in the produced fluids and increase oil production. For this reason, our company has developed a family of partially-hydrolyzed polyacrylamides which can fully meet the requirement of the customers' oilfield EOR operation. Our customers may choose our products according to the characteristics of their oilfield (such as formation temperature, salinity of formation btine, viscosity yield of the injected polymersolution,etc.).

2. Tertiary systems: Surfactant/polymer and alkaline/surfactant/polyacrylamide combination systems and advanced forms of chemical oil recovery. Through many years' of research and investigation. it has shown that a tertiary system can be superior to other chemical systems with respect to chemical utilization, extent of oil recovery increase, and investment payoff. More than 20% of residual oil (after water flooding) can be recovered by the tertiary system. The incremental oil recovery from application of this system is from the residual oil which is impossible to be recovered by water drive and/or polymer drive. The newly developed EORPAM-3 and EORPAM-4 polymer have achieved the molecular weight in the range of 18-25 million, with which, when combined with 1.2% alkaline (without counting the influence of surfactant) at 1000 ppm concentration, can yield a viscosity of 30-35 mpa.s.
