DEVICE FOR PRODUCTIVE waterflood oil pool NATURAL chloride solution hydrogeological LOWER ZONE

摘要

The device refers to the practice of oil field development. It aims at creating conditions for the opening in the sole productive reservoir isolated from its reservoir and then blocks containing hydrocarbons (HC), and attaching them to a system of effective porosity productive horizon deposits.; It is known that aqueous solutions of chloride in a closed volume under the action of the geothermal gradient corroded hot soleplate its collector exposing isolated enclosed pores therein. In this case, the clay minerals under the influence of chloride solutions dehydrated, aggregate and open clogged passages of communication between the pores.; Lower hydrogeological zone to which the oil fields are confined, characterized by huge static inventory of highly chloro-soda-Calcium waters and brines, particularly in the deeply buried sediment complexes [1, 2]. And in the bottom portions of most productive reservoirs of hydrocarbon deposits are freshened condensing water and a dissolving isolated from "background" for gas basins chloride solutions [4, 5]. Bottom water desalination hydrocarbon deposits, as are hydrocarbons, in relation to the solid phase components are not aggressive and its collector soleplate not corrode [6].; The inventive device comprises at least one well drilled through the reservoir until the reservoir natural chloride solution. Possible to use two or more wells drilled through the opposite flanks of the deposit in order to accelerate the water exchange between the water in the reservoir and HC chloride solution.
