Abstract
Опыт применения технологий ограничения водопритока и ремонтно-изоляционных работ в трещиноватых карбонатных коллекторах
Highlights
Technologies are noted that showed positive technological efficiency
Experience in the development of carbonate reservoirs is already more than 60 years, which is quite extensive and successful; problem of oil production from carbonate deposits is covered in the scientific literature widely enough
In this article we present the results of works on water shut-off and remedial cementing in wells, the section of which is represented with fractured carbonate reservoirs
Summary
In operating range) based on the water-swellable rubber and urethane crumbs swell poorly in formation water; such products have a very high cost. The article (Lymar, 2011) reviewed the results of field tests in wells of oil fields of the Republic of Belarus, water shutoff compositions based on chemical reactants GPAN, OVP-1 and ACOR-BN 102, as well as a new method for the selective isolation and integrated technology. Completed pilot tests of water inflow solation technology in a horizontal wellbore confirmed the effectiveness of the proposed selective waterproofing technology in terms of oil deposits of the Republic of Belarus, and the efficiency of the developed water-isolating compositions based on chemicals GPAN and ACOR-BN 102 (Lymar et al, 2006)
