COMPREHENSIVE ASSESSMENT OF INFLOW PROFILE AND OIL SATURATION OF THE PRODUCTIVE HORIZON AT THE MORSKAYA FIELD

Abstract

This article presents the results of comprehensive geophysical studies of the well of the "Morskaya" field, aimed at assessing the inflow profile, the nature of saturation and the current state of productive horizons. The research was carried out using a complex of field and geophysical methods, including pulsed neutron-neutron logging, thermometry, resistivimetry, barometry and mechanical flowmetry. The use of a combination of these methods made it possible to conduct a detailed analysis of the filtration and capacitance properties of collectors, determine the nature of fluid saturation and identify the features of the individual perforation intervals.

In the process of interpreting the geophysical data, oil-saturated, residual-oil-saturated and water-saturated intervals of productive formations were identified, as well as zones of active fluid inflow. Additionally, signs of reservoir water intake were identified and the intervals of possible well flooding were determined. Based on the analysis of the distribution of temperature, pressure and flow profile, the efficiency of the perforated intervals and the nature of the interaction of the reservoir with the well during operation are estimated.

The results obtained make it possible to clarify the current state of the productive horizons of the Morskaya field, increase the reliability of the assessment of reservoir oil saturation, and substantiate recommendations for further optimizing the well operation mode and improving the efficiency of field development in modern field and geological conditions.
