Improving the efficiency of processing the results of reservoir filtration studies and parameters when modeling complex oil reserves

Abstract

The issues of improving the efficiency of processing the results of studies of the filtration properties of reservoirs within the oil and gas producing areas of the central part of the West Siberian oil and gas province are considered. The high degree of development of the hydrocarbon resources of the studied territory is characterized by the presence of long-term developed deposits, which determines the solution of tasks aimed at increasing the success of the search for complex deep-lying reservoirs, the efficiency of their exploration and additional exploration, since the overlying productive horizons are practically developed. This task is one of the most important at the current stage of field development in this region, in the context of falling oil production at the main large fields, and has no unambiguous solution.This article covers the issues of reservoir modeling using new scientific and methodological approaches to the processing of geophysical data and the possibility of using modern software products when grouping development objects according to criteria corresponding to a reservoir of a certain lithotype. This approach allowed us to build high-quality geological models and justify the use of the most effective complex of geophysical studies for modeling low-amplitude (no more than 15 m) and small-sized (less than 20 km2) oil deposits. In the course of research: The results of the reservoir filtration properties were processed; low-amplitude and small-size sediments of channel sediments (river valleys) were established; the industrial oil and gas content of complex sediments characterized by low-amplitude and small-size sediments (Tyumen formation, object Ю2) was proved; The interpretation of geophysical studies of wells was carried out, the results were compared with the energy characteristics of the reflected waves (seismic studies), zones saturated with water-oil-gas fluid were established (3D models were built), and the possibility of using this technique for identifying and mapping complex deep oil deposits was shown.
