Abstract: Many studies show that formation water is formed in gas wells during operation. This is mainly due to the watering of exploitation wells. In some cases, this occurs when an antihydrite or corrosion inhibitor is applied to the gas well.
In the indicated processes, the hydrostatic pressure and the pressure spent on losses are explained by the formation of liquid in the gas phase. As a result, some error occurs when calculating the bottomhole pressure. Therefore, treating two-phase flow as one-phase flow is a big mistake.
During hydrodynamic reports, wellhead parameters are taken as the main indicators. With the help of given parameters, riser pipe pressure distribution and well bottom pressure are determined.
In small production wells, the presence of a fluid column creates a more difficult operation technology. Therefore, the presence of a fluid column in the well causes a change in both the well bottom pressure and formation pressure. Therefore, the main reason for the change in pressure is the presence of fluid in the well.
Key words: oil fields, fountain exploitation wells, mining data, determination of well bottom pressure, reservoir pressure

1. Introduction: The movement of the gas-liquid mixture in the pipe - the hydrodynamics of two-phase flows is one of the new fields of science. It is a branch of fluid mechanics based on the laws of homogeneous liquids and gases. The conducted analyzes show that the hydrodynamics of two-phase systems is in the initial state, that is, this field is making its initial steps. However, it should be noted that such actions can often be found in nature and technology. However, in these studies, only certain separate sections of two-phase systems were reflected. One of the works shown in this direction is very different from the movement of suspensions. Thus, from the point of view of structure, the presence of five structures in the gas-liquid mixture in general, and from the point of view of the regime, the existence of four regimes is one of the necessary conditions. Therefore, differences in structure or regimes create differences in hydrodynamic laws.
