Abstract

In this article, we analyze the existing methods for limiting water inflow in wells and the problems associated with them. The fields, their geological structure, fluid properties and geological exploration of the blocks under consideration were also considered and analyzed. To fully understand the problem, we analyzed the development status, the properties of polymers and their effect on additional production. Based on the analysis results of different articles, we made an approximate forecast until 2019 using polymer flooding. The work purpose is to analyze the methods for limiting the water inflow introduced and used today. Many researchers have also set the goal of studying the application relevance of restriction methods. To achieve this goal, it is necessary to analyze, study the application effectiveness and the economic feasibility of the proposed method for limiting water inflow in the well. As an example, we considered and analyzed different measures to limit water inflow at a late stage of development

Introduction

The purpose of this work is the forecast of additional development of deposits using geological and technical measures at a late stage [1]. To achieve this goal, it was necessary to analyze the following main issues and solve the following tasks: 1) to study the geological structure and oil content of the reservoir in question; 2) to study the geological and physical characteristics of the oil reservoir; 3) to consider and analyze the dynamics of the reagents used; 4) to study the properties of polymers; 5) to evaluate the technological efficiency of the use of polymers by the method; 6) to analyze patents on the limitation of water inflow; 7) to propose a new method of limiting water inflow based on a natural catalyst. Today, the main problem in oil production is water cut [1]. Well watering leads to large losses of oil and gas, which negatively affects production, and therefore the economy. The researchers are actively working in this direction, but the results of applying new and previously known technologies for limiting water inflow are not 100% effective. This problem occurs due to a misunderstanding of the causes of water entering the wells and an incorrect selection of materials and technologies during repair and insulation works at the wells.

Conclusion

In the work, we considered and analyzed modern methods of limiting water inflow. A competent analysis and a correct understanding of the problem of water cut contribute to an effective approach to solving the global problem. It is necessary to use the injection of reagents that contribute to a significant increase in the layer permeability at the fields [1] As a result of the analyzed work and costs, we calculated the approximate costs of isolation: • Net profit amounted to 191.10 thousand manat per day; • Economic effect amounted to 238.88 thousand manat. According to the calculated approximate results, it is assumed that the proposed operation can pay off in 2 weeks of operation along the well with an oil production rate of 210 tons/day. The data are calculated on the example of the X field. For safe and stable operation, compliance with industrial safety is also necessary, without violating the basic requirements that may entail undesirable consequences. It is also necessary to comply with the requirements to eliminate accidents that may entail environmental consequences, which can lead to environmental disaster. As we know, the violation that led to the emergency as a result of this is pollution of the soil, groundwater and environment. The environmental situation in the country is also on the verge. Therefore, observing all the requirements, the use of proven (organic) compositions, in turn, may entail consequences that reduce the negative impact on the outside world. Using the hydrodynamic model, it is possible to predict and simulate the process of pumping polymer solution
