RATIONALE FOR THE CHOICE OF THE TECHNICAL SYSTEM AT THE INTENSIFICATION OF OIL PRODUCTION IN THE KRASNODAR TERRITORY
The heterogeneity of reservoir properties both along the section and along strike, resulting in uneven oil recovery and reduce the oil recovery factor on a layer as a whole. The solution to this problem is reduced to the disclosure of cracks due to a variety of methods. In the context of this article, the solution is reduced to a set of operations, wave action, supported by the injection of polymer composites. An important feature of the narrow beam of waves (CNF) is operative to obtain results in real time. According to the results obtained by the reflected waves are studying the process of modifying the pore space at the points of wave action. This process is characterized as a random multiplier for which the fixed parameters are the mean, variance and autocorrelation function. These parameters are defined by such characteristics geomedium as stress state, stress fracture, physical and mechanical properties and the type of fluid saturation. Work on CNF technology can be divided into short-term and long-term periods. In the first case the exposure is performed for 1–2 hours to study the results of the stimulation and the cracks structure changes. Further, prolonged exposure to 5 hours with gradual pumping weakly acidic emulsion composite. So, CNF technology allows you to control the expansion of cracks in real time and stop it promptly, preventing its negative development. Turning to data dependencies, it is concluded that the knowledge of fracture parameters can be adjusting wave source parameters to achieve the maximum effect of cracks in its minor localization. Thus, the overall effect on the formation, which may lead to negative consequences, is minimized, thereby avoiding the load on the environment.
