Abstract:
Depletion and deterioration of the structure of reserves in the fields of Western Siberia requires the involvement in the development and operation of hydrocarbon deposits represented by reservoirs with secondary filtration-volumetric properties and complex heterogeneous structure. A technology, which is successfully applied by resource companies, uses multilateral wells. Development of deposits using such wells is complicated by the choice of the optimal layout and development system for a particular field. Our goal is to propose a common approach to the creation of an optimal system for the development of oil fields.
To solve this problem, it is reasonable to develop an analytical calculation method that performs express assessment of the fluid inflow to a dual-lateral well avoiding the use of multivariate and time-consuming calculations by hydrodynamic models built in a simulator. In this work, such an analytical method is developed and verified using the actual geological and geophysical data on the productive Neocomian deposits of the Severo-Ostrovnoye field in Khanty-Mansi autonomous okrug.
