In order to reduce watering of wells and equalize their injectivity profiles, the prospects introducing PPG technology in Russian fields are considered, which preformed particles polymer gel pumped into injection well. These particles, being a supersorbent based on polyacrylamide, absorb water, become elastic, allows them shrink tear narrow filtration channels. When is filtered along permeable layers saturated with accumulate waterlogged intervals thus they form plug, redistributes flows...
Due to the constant increase in number of fields entering final stage operation, oil companies are increasing their demand for integrated technologies that can simultaneously coverage formation by displacement process and reduce water cut well products. In this case, traditional technology is flooding with viscous solutions water-soluble polyacrylamide. The article provides an overview polymer technology, identifies advantages disadvantages approach, particular, lists factors influence...
One of the main oil production complications is that asphaltene-resin-paraffin deposits (ARPD) are formed during wells' operation. This an urgent problem in and gas industry, especially fields Ural-Volga region (Russia). study aimed to develop a technological solution for effective thermal treatment based on state calculation sucker rod pump In practice, effect ARPD carried out by flushing-out with hot agent (water, oil). Traditionally, flushes through casing annulus. However, this method...
The technology of conformance control using preformed particle gel was considered for oil deposits Perm kray, Russia. These are characterized by low temperature (20–30 °C) and reservoir water high level mineralization (230 g/l). absorption ability commercially available l polymers under conditions is 3–20 g/g that not enough treatment. Authors synthesized the polymer superabsorbent bloc co-polymerization method. structure made crosslinked polyacrylamide chains contain co-monomers with...
