Description
Summary:The paper1 considers compatibility of formation water of the Irelyakh gas and oil field of the Republic of Sakha (Yakutia) with the highly mineralized solution used as an agent of reservoir pressure maintenance (RPM) with an allowance for factors, which influence solubility of salts, salt effect in particular. Also, possibility of concurrent reactions and specific conditions characteristic of the fields of the southwest Yakutia (by the example of the Irelyakh GOF) have been taken into account. It is shown that with the increase of the time length of wells ’ flooding with the liquid for RPM the pore space structure undergoes changes due to its calcination and sulphatization, which causes deterioration of reservoir properties and subsequently can complicate the operation of producing wells and the field in the whole. The advanced development of the national oil industry is stipulated not only by the increase in a number of production facilities but also by further improvement of technical equipment and oil production technology as well as optimization of production processes. Specific feature of the fields of the southwest Yakutia is abnormally low formation temperatures, which causes the increase in oil viscosity and brings about the
