摘要
压裂是低渗或特低渗油层增产的主要方法。压裂液破胶不及时、不彻底乃至在裂缝中形成滤饼,降低了油层裂缝的导流能力。采用一种专门用于降解聚合物和生物堵塞的HRS复合解堵剂于压裂工艺,提高了压裂的导流能力,达到了增油的目的。
The press-cracking technique is the main measure for increasing the output of oil layer in the condition of low pentration or lowest pentration.Due to imperfection cracking of the press-cracking liquor and even the filter-cake formed in the crack,thus the flowing ability of oil-stream in the oil layer crack will be decreased.A special antiblocking agent HRS,which is used for the degradation of the polymer and biological organism,is adopted in the press-cracking process.Not only the flowing ability of oil-stream is improved,but also the output of oil is increased.
