AN IMPROVED PROCESS FOR PRODUCING MINERAL OIL FROM STORING ROCKS CONTAINING CLAY MINERALS, SAND STONES SANDS AND MARLACEOUS SAND STONES BY INJECTING WATER INTO THE STORING ROCK
AN IMPROVED PROCESS FOR PRODUCING MINERAL OIL FROM STORING ROCKS CONTAINING CLAY MINERALS, SAND STONES SANDS AND MARLACEOUS SAND STONES BY INJECTING WATER INTO THE STORING ROCK
A method for injecting water into fluid storing rocks containing clay minerals, in particular in hydrocarbon sites formed by sandstones, sands, marlaceous sandstones, water storing rocks, geothermic circulation sites, in zones in the vicinity of wells, extending to large sites. Continuously or discontinuously compounds are introduced into the storing rocks having a hydrated cation diameter in the range between 0.13 and 0.15 nm, a coordination number 12. The compounds are preferably potassium-, and/or ammonium-, and/or zirconium salts. Depending on the clay content of the storing rock, stabilization is performed by using a solution of the enumerated salts in a concentration of 0.1-500 g/l, advantageously 0.1 to 300 g/l, and in a quantity of 0.5 to 5000 m3, preferably 50 to 3000 m3, which is related to the vertical dimension of the rock, expressed in meters.
