The article considers influence of gravitational forces on formation of replacement front and on consequent of deposit areas development during water-flooding and gas impact on condition of presence of local dome lifting and its absence. Isotropic and permeably homogeneous deposit is taken as an example. Data of numerical studies witnesses increase of oil recovery coefficient as well as prolongation of dry operation period in case of presence of local lifting under gas impact as compared with water-flooding.
Key words: isotropic collector; water-flooding; gas impact; modeling of oil recovery processes.

20, Azadlyg prospect, Baku, Azerbaijan.
High accuracy of digital-analogue converter is known to be one of basic conditions for success of iterative error correction. The algorithm with definition of initial point of iteration allows lowering requirements to accuracy of digital-analogue converter because it might substantially reduce influence of its error on measurement result.
Key words: iteration correction of error; measurement result.
