A polymer gel-surfactant composition profile control technology has been developed, basing on the high salinity, especially high levels of Ca2+, Mg2+ in the injection water of the Hongshanzui oilfield. The construction parameters of deep profile control & oil displacement have been studied by performing core displacement experiments. The results show that the ratio of polymer gel slug and active agents slug is 1:0.3, the best ratio of strong polymer gel, medium polymer gel and weak polymer gel slug is 4:3:3. The way of combination is stronger gel slug + surfactant slug + in strong gel slug + weak gel slug + surfactant slug + strong gel sealing slug. The application effect of this technology in Hongshanzui oilfield is remarkable, the 12 tune flooding group daily oil production rose from 85t to 130t and the liquid water content decreased from 75% to 67%.

Polymer flooding is technologically simple and highly effective method of enhanced oil recovery. The method is based on adding a small amount of polymer in conventional water flooding of oil reservoirs. The increase in viscosity and the reduction of the mobility of injected water are to equalize the displacement front by slowing the moving of water in the highly permeable zones and restricting the formation of water finger. These factors help to increase the sweep efficiency and oil-water displacement efficiency during flooding. Polymer flooding has been used successfully in clastic and carbonate reservoirs, as well as in low-permeability reservoirs such as a fractured basement. However, most of the current polymer gel used for control water flows are decayed by a high content of ions Ca2+ and Mg2+ in formation water or in injected water. Similarly, polymer gels lose their stability at high reservoir temperature (above 70°C). Developing water-soluble polymer, which does not change their rheological properties under high salinity and high temperature (over 100°C), is very important when producing offshore, where sea water is commonly used for flooding (high salinity of 30-40 g/L).

Network Morphology

The rheological and mechanical properties of crosslinked polymer gels arise from the structure of the gel network. In turn, the structure of the gel network results from: thermodynamically determined interactions between the polymer chain segments, the interactions of the crosslinking metal ion with the polymer, and the deformation history of the network. Interpretations of mechanical and rheological measurements on polymer gels invariably begin with a conceptual model of,the microstructure of the gel network derived from polymer kinetic theory. In the present work, we use freeze-etch replication TEM to image the polymer network morphology of titanium crosslinked hydroxypropyl guars in an attempt to directly relate macroscopic phenomena with network structure.
