采用新的注入地层方式,在油层内自已产生微粒,并能大剂量作业,可以提高封堵效果的调剖技术,在现场运用一年多,已累计增油2362t,投入产出比1:5.4。采油工艺研究院与采油三厂合作,从1996年开始自生微粒调堵技术研究,同年6月在五西区现场施工1井次,观察4个月油井见较好增油降水效果。总结经验,不断改进完善技术措施,至1997年底先后在五西
Adopting a new method of injection into the stratum, generating particles in the oil layer itself, and capable of large-dose operation, the profile control technology that can improve the sealing effect. It has been used in the field for more than one year and has accumulated 2362 tons of oil, with an input-output ratio of 1:5.4. . The Oil Production Process Research Institute cooperated with the No. 3 Oil Production Plant and began to study the technique of self-adjusting particle blocking in 1996. In June of the same year, the construction of a well was performed on the site of the Wuxi District, and observation of the effect of better oil and precipitation on the oil well for 4 months was observed. Summing up experience, continuously improving and perfecting technical measures, and successively
