Hinge and Christensen considered a model system of particles with solid polystyrene core and poly(N-isopropylacrylamide) gel surface. 226 Using a model for deformable particles, they modeled the specific cake resistance as a function of the low amount of gel (thin shell layer). At the high amount of gel (thick shell layer), the permeability of ...

Aug 26, 2021 · In this study, widely used methods like modified plunge, pH, suspend solid content and shaking tests are adopted to find the appropriated methods in expressing water resistance of Underwater cement paste (UWP). The visual inspection and parameter diagram are firstly analyzed and results show that, compared with the other two tests, the characters like water …

Adding trace PAM in water can reduce the resistance by%. Thickening: PAM has a thickening effect under neutral and acid conditions. When pH is above 10, PAM is easy to hydrolyze. When it is semi-mesh, the thickening will be …

Dec 02, 2019 · 3.1 Development and application of novel salt-resistant polymers. Bohai oil field has the characteristics of high crude oil viscosity, large well spacing, high water salinity, and limited platform space. Thus, the suitable polymer agent should have high-viscosity property, good salt tolerance, aging stability, and fast-dissolution ability.

Jun 24, 2020 · The present invention relates to a carbonate reservoir filtration-loss self-reducing acid fracturing method. The carbonate reservoir filtration-loss self-reducing acid fracturing method comprises the steps: (1) calculating a fracture pressure and a fracture extension pressure of a reconstructed reservoir; (2) injecting an agent A into a stratum under a pressure higher …

Feb 21, 2020 · The first electrolytes of this type used silica functionalized with alkyl-sulfonate groups, 103,104 which show conductivity between 10 −6 s cm −1 and 10 −4 s cm −1, depending on the host matrix. The type of anionic group, functionalization density, chain length and flexibility are critical to obtain higher dissociation and conductivity.

Sep 07, 2017 · Water control is a key issue in most of hydrocarbon reservoirs (Liu et al. 2010; Salehi et al. 2014; Yadav and Mahto 2013a).Polymer gels are widely used to control water production by blocking the high-permeability zones in heterogeneous mature reservoirs and then diverting the water to the low-permeability zones during enhanced oil recovery operations.

It can replace 15%~20% starch. (Our company can provide detailed starch gelatinization process for reference) Packaging and storage: This product is a solid particle, convenient to transport and use, placed in dry, ventilated, cool place. Do not in contact with water to prevent the dissolution loss. Packing in 25kg plastic bag.

Conventional polymer flooding include polymer flooding, surfactant-polymer flooding (SP), alkaline-surfactant-polymer flooding (ASP), and crosslinked polymer gel flooding. However, these technologies in oilfield, especially in high temperature and high salinity, are limited due to the poor ability of temperature and salinity resistance of polymer. In this work, a novel polymer particle …

These types of NLC are called multiple types NLC, and are analogous to w/o/w emulsions since it is an oil-in-solid lipid-in-water dispersion. Since drug expulsion is caused by ongoing crystallization or transformation of the solid lipid, this can be prevented by the formation of a third type, the amorphous type NLC.

a water soluble salt such as a normal salt prepared from a metal such as k, na, li, or mg and a dibasic acid is added to the cation modified polymer aqueous solution to separate a polymer. the resulting polymer is subjected to dehydration and drying at a temperature of below 80*c. thereby to prepare a cationic water soluble polymer.

Another fouling-resistant and -release approach was developed by Chen and co-workers, who grafted a salt-responsive brush of zwitterionic poly(3-(1-(4-vinylbenzyl)-1H-imidazol-3-ium-3-yl) propane-1-sulfonate) (polyVBIPS) onto a gold surface, which was able to switch reversibly and repeatedly between protein capture/release and surface ...

1.1. Overview of Polymer-Enhanced Oil Recovery. Although oil production is currently assumed to be higher than the actual demand, the future of oil and gas production will have to tackle severe challenges: fewer new fields are found and major producing fields show declining production.

The Sb–SnO2-based HEC recorded a remarkable short circuit current density, Isc ∼ 23.2 mA/cm2, and peak output power, Pout ∼ 32.2 mW/cm2. Antimony doping decreases the bulk resistance of the cell by 45 times due to highly accelerated OH– and H3O+ conduction in Sb–SnO2 HEC as observed by Nyquist plots.
