REVIEW OF MODERN METHOD OF INTERPRETATION OF WELL TEST WITH FRACTURED POROUS RESERVOIRS

摘要

Study of state and reservoir properties is possible with the laboratory, geophysical and hydrodynamic methods. Laboratory methods are based on the study of the core. Currently, there is quite wide range of laboratory equipment to study the parameters of rocks. Geophysical studies allow us to determine the average properties of the producing formation are only a short distance from the borehole wall. Hydrodynamic research methods, in turn, allow us to determine the mean values at a considerable distance from the well, which contributes to the definition of more information on the work of formation.Well test are very important because they are the only more or less reliable source of information about the permeability and porosity of the reservoir and the section as a whole.Feeling of relative well-being and some of completion reached in the direction of hydrodynamic studies of oil and gas science is somewhat misleading. Often the problem of determining the filtration characteristics of the reservoir are unstable with respect to inaccurate input data.Today, there are quite a number of commercial software products, allows us to interpret the results of field research. But often these packages are still far from perfect.Development of oil and gas deposits with carbonate reservoirs characterized by a number of specific features associated with the passage of fluid into the medium with double porosity. Development of methods of mathematical modeling fluid flow in this environment is an important task.Today there is no question of the leading roles in the filtration properties of fractured tight reservoir rocks. This is natural, because the fracture of rocks dramatically increases their permeability. Thus, the technology development of deposits with the data collectors can be effectively carried out only on the basis of a comprehensive study of filtering mechanisms in heterogeneous fractured porous reservoirs.
