In order to apply the technique of polymer flooding to the offshore oilfield, some contraventions (the large well spacing, the high salinity formation water, the narrow production platform space, the limited load capacity, the slow dissolution of hydrophobically associating polymer, the voluminous existing polymer injection equipment) must be faced. In order to resolve the problems, a study on the efficient polymer dissolving technology for hydrophobically associating polymer flooding on offshore platform was conducted. The principle of polymer rapid dissolution was analyzed on its restrictive factors. By comprehensive utilization of multi-disciplinary angle of studying from polymer materials, fluid mechanics, et al, the efficient polymer dissolving technology was formed by means of compulsory stretching and water logging for polymer molecular chains, and break through the "bottlenecks" of polymer rapid dissolution. The designed dispersing & dissolving equipment cut down the polymer dissolution time from 60 min to 40 min. Meanwhile, the auto-unloading device, metering device, curing system, injection system, and automatic control system were optimized. Compared with the original equipment, the novel one’s occupied area and operating weight decreased by 21% and 37%, respectively. The efficient injection allocation technology was applied to the polymer flooding pilot testing in Bohai bay so as to provide key technology and equipment support for cumulative incremental oil 395×104 m3 (up to June, 2014), incremental output value 12 billion yuan (estimated by the barrel oil price $90).

The effect of ageing time on the macromolecular composition and conformation on intermolecular entanglement and crosslinking was investigated for a water-soluble, hydrophobically associating polymer (WSHAP), by steady-flow and oscillatory experiments at reservoir temperature (65 °C). The measurement of rheological properties was carried out with changing sample properties such as shear stress, shear rate and storage time. Moreover, for the investigated samples, the mathematical interpretation of relationship between the modulusGand the shear rate γ according to the Ostwald de Waele (power law) model, was carried out. Energy of viscous flow (Ea) has also been determined and discussed.
