加砂压裂用滑溜水返排液重复利用技术
Reuse technology of slick water fracturing flowback fluid
摘要
Abstract
Volume-fracturing in unconventional reservoirs needs massive fluid and brings plen-ty of flow-back fluid which contains varied ions ,residual additives ,suspending matters and so on ,so harmless disposal has great difficulties .This paper introduced the ways of disposal flow-back fluid from volume-fracturing ,and combined the actual circumstance of unconventional gas well in Sichuan .We formed the disposal flow-back fluid process .Laboratory study showed that concentration of residual additives were low in flow-back fluid ,but had a certain amount of total dissolved salts ,the drag friction of the treated flow-back fluid was the same as the fracturing flu-id produced by the freshwater .It also came to the same conclusion in field trial ,which gained ef-ficient reservoir reformation ,saved freshwater ,reduced drainage of waste water ,and achieved energy conservation and emission reduction .关键词
