"ANALYSIS OF EFFECTIVENESS OF GEOLOGICAL-TECHNOLOGICAL ACTIVITIES DURING TREATMENT OF FORMATION CRITICAL ZONE (BOTTOM HOLE) OF INJECTION WELLS IN VOSTOCHNO-LENINOGORSKY FIELD OF OIL-AND-GAS PRODUCTION DEPARTMENT "AZNAKAYEVSKNEFT".
L.G. Rakhmaev
Ufa State Petroleum Technical University
The article considers efficiency of three geological-technological procedures (hydrochloric acid treatment, formation hydraulic fracturing, viscous-elastic colloid system on the basis of alkali silicate) recently performed in Vostochno-Leninogorsky territory of Romashkinsky oil field, where injection wells are located. The impact of such geophysical factors as formation thickness, porosity, permeability, oil saturation, and clayiness on incremental ultimate recovery was appraised. Limiting values of the geophysical parameters, securing economic profitability of treatment of formation critical zone (bottom hole) were determined.
Key words: well; formation; injectivity; thickness; porosity; permeability; production.

Results of the carried out investigation proved separation of gasliquid mixture inside lift into gas and liquid phases, being under the influence of diverse forces, during singlestring gas-lift well operation. This is followed by formation of a liquid column of a certain height inside lift. Presence of this liquid column quite considerably influences upon value of bottomhole pressure. Description of researches on determination of indicated liquid column height and its relationship with bottom-hole pressure is given in the article.
Key words: producing well; operation method; lift (hoist); bottomhole pressure; shoe pressure; daily production rate; depression on a formation.
