The hydrocarbon reservoirs in mature regions are extremely complex, each reservoir having its own identity. The value of recoverable geological reserves depends on the data of geological and geophysical studies: determination of heterogeneity and reservoir compartmentalization. Residual oil reserves are concentrated in undeveloped clayey, poorly permeable intervals along the section, the development of which is impossible without research and development. One of such studies is the methods of lineament analysis of the territory, well to well tracer test.
The area of the traditional method of tracer studies is the establishment of macro-heterogeneity and filtration-capacitive properties and the study of real filtration flows of a productive formation by introducing a labeled fluid into an injection well, which is pushed to the producing wells by a displacing agent, sampling from production wells, their subsequent laboratory analysis and interpretation of the results. The need for this kind of research is due to the establishment of the direction and dynamics of the advance of the waterflooding front over the reservoir area. After the injection of 2 types of tracer into the injection wells of the field, samples were taken for 150 days. During this study, signals were recorded in three wells and 6 filtration channels were identified. After that, an interpretation was made, during which the velocities of the labeled liquid along the identified channels of low filtration resistance (LFR) and the filtration-capacitive properties of the channels were calculated. These channels represent the channels of morphometry associated with the tectonic activity of the South Tatar arch. As a result of the tracer studies, it turned out that the production wells No. 196 and 295 are affected by the injection wells No. 271 and 188, respectively, which was not previously taken into account in the specifics of the development. It was proposed to revise the coefficients of well interference. |
