摘要

The article deals with the increase of profitability of water shutoff treatment (WST), which is used to eliminate behind-the-casing flows (cross-flow) in production and injection wells. It is presented that modern technologies of water shut-off works have low efficiency (success rate), especially in liquidation of non-perforating interval. Inefficient (wasteful) injection is currently one of the main problems in the development of oil and gas fields, as it significantly reduces the oil recovery factor in addition to the huge costs for oil companies for injection (operating costs). The article presents the results of hydrodynamic research and proposes methods for determining the presence of behind-the-casing flows (BCF) and methods for detecting wasteful injection without geophysical well-logging (a non-standard approach). The article also presents equipment for the elimination of the behind-the-casing flow and technology of its implementation.
