Mechanical methods of flow-diverting agents during acid treatment

An effective diversion technique is a crucial component in all acid stimulation jobs, which allows us to achieve full zonal coverage and thereby the treatment objectives. In process of acidizing heterogeneous formations, it necessary change direction fluid target interval, i.e., interval with low permeability, ensure an even distribution pumped fluids throughout formation. This because due different permeability layers, highly permeable wormholes can be treated acid, remain untreated. The article describes technological features methods flow-diverting agents (diversion methods) used flow prevent this problem, i.e. optimal placement. article, one mechanical agents, Coil tubing technology, considered its effectiveness determined by conducting quantitative experimental studies.
