Abstract
Summary
To date, the acid treatment of the bottomhole formation zone is one of the most common and effective geological and technical activities on the fields of the Perm region of hydrocarbons. These geological and engineering is used as the carbonate, and in clastic reservoirs, while, as a rule, based on the acid compounds are used either hydrochloric (HCl), or “mud” (HCl + HF) acid, respectively. The acid treatment is carried out as in the old fund of wells when the filtration properties of the bottomhole formation zone significantly reduced loss of asphalt-paraffins, salt and rock particles and the newly drilled wells for cleaning the bottomhole formation zone of process fluids - mud and killing compounds. Theoretically, the acid treatment of the target range should improve hydrodynamic connection with the formation of the well, but is not uncommon after such well interventions hydrocarbon production rates, not only did not increase, but decrease. In this paper, the authors present some of the results of laboratory studies of acid treatments clastic rocks as it is timed to 38% of the reserves of hydrocarbon deposits of the Perm Prikamye.
