Abstract

In the world practice of hydrocarbon reservoirs design there is the steady tendency of rate increasing for underground reservoirs design in impermeable rocks. Design of underground reservoirs that are created in rock-salt sediments is intensively directed by the geotechnological method. It is determined by many economic and ecological advantages. One of the main tasks during renewal works of technological wells sealness for underground reservoirs in salt-rocks is the necessity to insulate the excavation-capacity of big geometrical volume filled by saturated sodium-chloride brine from technological well. The main point of offered technology is to develop stable with brine-contact flush fluid that is delivered on the brine surface with the aim to provide a possibility to install intermediate bridge for renewal works realization of borehole annulus sealness of main casing string and cementing of addi-tional casing string using pakers and lightened drilling mud. The application of new scientific-technical developments allows providing a stable level of gas recovery from underground reser-voirs wells due to the increasing of the overhaul period of its op-eration and the reducing of repair duration.
