摘要

Process for eliminating clays from rocks and sedimentary environments, in particular rocks that are reservoirs of hydrocarbons, and/or water, and/or natural gas, or bituminous schists, or asphaltic sands, consisting in applying into the said sedimentary environments or rocks organo-silicon compounds of one of these two formulae': < IMG > (A) (B) in which : - n is a whole number between 1 and 1,000 and preferably between 1 and 50; - p,q and r are whole numbers between 0 and 1,000 and preferably between 0 to 50; - R and R' represent a group that is linear aliphatic, ramified or cyclic, saturated or not, ramified heterolinear or not, saturated cyclic or not, aromatic, heteroaromatic, aryl-aliphatlc or hetero-aryl-aliphatic, which can be equally functional, or a combination of these various possibilities; R can also be OH, OR or OSiR3; - .SIGMA. being R, or H, or SiR3; - .SIGMA.'being R, and more particularly Me, or OR, or OH, or OSiR3. Application to recovery of oil.
