Abstract
In recent years, there has been a trend of mass introduction and an increase in the share of horizontal wells including injection wells, mainly in conditions of hard-to-recover reserves. The paper compares the coefficients of horizontal wells’ pick-up and compares them with directional wells, in order to determine the area of their most effective application. For the first time in the practice of flooding with horizontal wells, the influence of such parameters as the length of horizontal wells, the number of stages and the loading of the proppant during hydraulic fracturing. Based on the results of the analysis, a new configuration of the development system is proposed.
Materials and methods
The data of the injectivity index of injection wells of more than 17 fields are analyzed, the correlation dependence of the multiplicity of the injectivity index on the permeability of the layers is constructed. The results of field geophysical studies were used: thermometry, noise measurement, flowmetry. Calculations were performed using a 3D hydrodynamic model in the PH-KIM simulator
