Features of well hydrodynamic studies to increase the geological exploration status of hydrocarbon deposits

Abstract

The article shows the results of planning and conducting hydrodynamic studies in producing wells analysis, which states that the pressure recovery curve (PRC) is an effective tool for solving problems of increasing the informativeness and knowledge of the reservoir energy state. The high degree of equipment with telemetry systems sensors (TSS) at the pump suction makes it possible to significantly increase the coverage of the field with estimates of reservoir parameters in the zones of drilling new wells. The depth sensors employment makes it possible to better succeed in reservoir pressure estimation and, as a result, eliminate an error in pressure recalculation. A large number of TSS sensors at producing wells allows us to digitalize the deposit, reduce losses in oil production by optimizing the research program and operational data using. The technology of express reservoir pressure estimation in the production and pressure analysis according to the data from the TSS sensor is considered in the article, which does not require a stop on the level recovery curve (LRC) or PRC, which thereby eliminates oil and liquid losses. This technique of reservoir pressure estimating allows to increase the coverage of research in fields with low-permeability reservoirs and in areas with high oil debits.
