The regularities of the reophysical behavior of polymer solutions during their flows in the model conditions of the oil seam- collector and regularities in oil and gas well that consist in observed dynamic structure formation due to the emergence of a highly molecular organization in the presence of negative feedback are established. Experimentally proved the hypothesis about the possible influence of the revealed effects of elastic deformations which arise during the flow of polymer solutions in in the entrance areas of holes porous medium and confuser and diffuser cells on a significant increase in efficiency of processes oil recovery ratio and flushing out of a well during drilling. High efficiency of the oil recovery ratio with using a non-stationary flow (the one that tighten up) of polymer solutions is theoretically substantiated and experimentally confirmed. The effects of highly dissipative mode in the oscillating mode of injection of a polymer solution in the seam play an important role in intensifying the oil recovery ratio with using polymer solutions. A new solution to the actual scientific and technical task is given, which consists in establishing the regularities of the manifestation of the effects of elastic deformations, Which arise at the filtration and confuser and diffuser flows of polymer solutions, which made it possible to develop recommendations for the intensification of oil recovery ratio and flushing out of a well with polymer solutions during drilling.
