PECULIARITIES OF HYDRODYNAMIC RESEARCH OF WELLS OF DEPOSITS OF NGDU “JAMASHNEFT” AND THEIR INTERPRETATION

摘要

Currently, there are many different methods of wells research, including hydrodynamic studies, which are an integral part of the monitoring of the generation of hydrocarbon reserves.The specialist must have sufficient and accurate information about the formation of its energy capabilities, wells opportunities for reliable analysis of performance and development of forecasting when the mining project development. Most of this information can be obtained from the results of studies of wells in the stationary mode.There are various methods of research and methods of treatment, which is in the conduct of non-stationary filtration conditions (research by the pressure / level recovery, the pressure drop method, the study in the injection method of level drop in the injection well and the wells Interference) is an important part of petroleum engineering.However, the presence of significant fund marginal wells leads to the fact that most of the pressure recovery curves (HPC) are no restoring. In addition to the short duration removing KVD significant drawback is usually a small number of dots on the HPC. No restoring curves affects the accuracy of determining the filtration parameters of the reservoir and the reservoir pressure.Given the problem no restoring HPC, including due to the high heterogeneity of reservoir properties development facilities, and spread well productivity values, it is necessary to develop an individual approach to each well and improve the methodology for conducting hydrodynamic studies of wells (well testing), followed by the selection of the optimal methods of processing of results of research . This will allow better well tests and their interpretation with respect to each object, taking into account geological and physical structure of the deposit and the physicochemical properties of the saturating fluids.
