OIL DEPOSIT DEVELOPMENT METHOD Russian patent published in 2020 - IPC E21B43/30 E21B43/20 E21B47/02 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry, namely, to development of oil reservoirs using production and injection wells. Method includes construction of at least two horizontal and/or inclined wells, each of which is equipped with forcing and producing sections located at distance excluding hydrodynamic connection, and separated by through packer. Injection and production sections are built parallel in plan within one reservoir of deposit for nearby wells with provision of hydrodynamic connection, injection of displacement agent into pressure section and extraction of products from production section of each well. Wells are constructed without changing the azimuth angle along the whole length. Injection and extraction sections are subjected to secondary opening taking into account injection and withdrawal points, respectively, providing for uniform distribution of flooding front and withdrawal by increase of total area of perforated holes in direct dependence on distance of working fluid injection point and formation product extraction point accordingly.

EFFECT: simplification of well construction.
