The decisive influence on the technology of drilling wells in Eastern Siberia is exerted by a complex of components of the geological section, the absorption of flushing fluid, AAP and temperature. Experience in well construction shows that in the fields, drilling was carried out on two types of water and oil-based fluids. Due to various circumstances, each of the types of solutions used in drilling had negative aspects during the construction of wells. The use of such solutions is not effective enough to solve the problem of opening intervals of salt deposits and high-quality primary opening of reservoirs. In order to assess the effectiveness of well construction, we applied the methodology for determining the potential production rate of wells based on the Dupuit formula for an imperfect vertical well. Analysis of the potential flow rates of wells built on the terrigenous reservoir of the Vostochno-Alinskoye field using traditional technologies (saturated saline biopolymer solution) showed that more than half of the wells did not reach potential productivity. The existing technology of well completion under conditions of constant repression on the reservoir, including the secondary opening of the productive horizon, negatively affects the reservoir properties of the object. Under the conditions of Vostochno-Alinskoye field the effective opening of the reservoir should be solved by applying technologies that prevent the penetration of working fluids and their filtrates into the reservoir. The essence of such technologies should be based on the creation of conditions that do not allow the excess of bottomhole pressure over the reservoir pressure of the exposed horizon. References 1.
