Abstract: The article analyzes organizational and technical actions when flooding the pressure tap wells on a linear section of the main pipelines. At present, only the fact of flooding is registered with fluid level indicators and the corresponding information is transferred to the control stations by means of telemechanics. It is proposed to improve the existing system for well flooding detection by expanding it with the help of the devices for identification of the surface layer fill fluid type.
The article formulates general requirements for the fluid type identification device and its operation principle, which is based on the use of the non-contact sounding method to determine the characteristic physical parameters of the fluids, the well cavity is filled with. This article considers the electrical and optical properties of oil and oil products, characterized by the dielectric constant and index of ultraviolet induced fluorescence, as image parameters. It also analyzes existing methods and modern devices for non-contact measurement of fluid parameters in order to use this information for development of the sensor for fluid type identification.
The introduction of this proposal will expand functional capabilities of the control and measuring equipment of the linear telemechanics. The information, obtained when determining the fluid type in the CI well, will allow rapid and optimal planning of the necessary means and measures to eliminate the identified violations on the main pipelines, which is especially important when increasing the length of the operated oil pipelines, as well as when there is a need to reduce unit costs.

Keywords: flooding of CI wells, fluid type identification, dielectric permittivity measurement, ultraviolet induced fluorescence, fluorescence detector of oil contamination, lidar of oil contamination.
