Abstract
Acid treatments is an effective and widely used method of influence on well bottom layer zone, designed to increase or restore the productivity of production and injectivity of injection wells.
The efficiency obtained when implementing technology in the wells directly depends on the quality selection of reagents in laboratory conditions for specific geological and physical conditions of the development objects. Insufficient coverage of laboratory studies may lead to a decrease in productivity of the reservoir to be treated, and as a consequence, the loss of oil production. To improve the quality of research is needed a unified approach to laboratory simulation that includes research in the “free volume” and filtration tests on of kern material.
In this work addressed the issue of an integrated approach to the study of laboratory reagents used at carrying out acid treatments. The order of studies acid compositions, including deflecting systems and failsafe acid compositions in the “free volume” for the different collectors and methods of making filtration tests on of real kern material based on rock thermobaric layer mode.
