The definition of water leakage in layer of viscous-plastic oil in edge-water and marginal floods

In the article the tasks of development of strip-like reservoirs of viscous-plastic oil are considered. In the reservoir a line of water injection wells and a line of producing oil wells are operating. With the purpose of keeping of layer pressure in deposit, the method of edge-water or marginal flooding is applied. For estimation of leak of water injected in layer in water bearing zone of the oil reservoir, hydrodynamic task is solved and the formulas of daily productivity of the line of injection wells shown. For determination of daily water discharge of the line of injection wells, inclining towards water bearing zone of the deposit, from the daily discharge of injection well line the flow rate of the line of producing wells is calculated. With the purpose of increase of this fields oil recovery coefficient, it is recommended to carry out the thermal treatment of bottom hole zone of producing wells and to conduct the injection of wastewater of oil industry by wells, located at the water bearing zone of reservoir beyond the line of injection wells to increase hydraulic resistance of this part of reservoir.
