摘要： A process for producing mineral oil from mineral oil deposits, in which the mineral oil yield is increased by blocking highly permeable regions of the mineral oil formation by separate injection of at least one acidic formulation which comprises water-soluble Al(III) salts, and one urea- or urea derivative-comprising formulation into the deposit, said formulations not mixing with one another until within the deposit, and the mixture forming highly viscous gels under the influence of the deposit temperature. The process can be used especially in the final stage of deposit development, when watering out in production increases, and particularly after the steam flooding of the deposits.

摘要： A process for producing mineral oil from underground mineral oil deposits. One or more flooding media is injected into an injection well and mineral oil is withdrawn from a production well. Highly permeable zones are blocked in the region between the injection well and the production well by injecting aqueous formulation F1 and aqueous formulation F2 each separately in succession through the injection well into the deposit. F1 and F2 mix with one another in the formation after injection to form viscous gels. F1 comprises water and urotropin and F2 comprises water and urea. F1 and/or F2 comprise(s) at least one further compound M selected from metal compounds and semimetal compounds, which further compound can form gels when admixed with bases, the injection well temperature before process step (2) being not more than 60° C.

摘要： A process for producing mineral oil from mineral oil deposits, in which the mineral oil yield is increased by blocking high-permeability regions of the mineral oil formation by injecting at least one formulation into the deposit, the formulation not being brought to a temperature at which the viscosity increases significantly until within the deposit, by injection of steam. The process can be used especially in the final stage of deposit development between water flooding and steam flooding of the deposits.

摘要： The present invention relates to a process for the production of mineral oil from mineral oil deposits with large temperature gradients, in which, for increasing the mineral oil yield, highly permeable regions of the mineral oil formation are blocked by injecting formulations which, after being forced into the deposit, form highly viscous gels under the influence of the deposit temperature. A plurality of portions of the formulation which in each case can form gels at different temperatures and therefore result in very complete blocking of highly permeable regions of the formation are used.
