老井重新试油的实践与认识

全面系统地分析了胜利油田一批稠油、特稠油、疏松砂岩油藏以及低渗透油层低产的原因。利用老井复查成果对该类油层进行重新试油，相继获得工业油流，结全实际井例，结合了老井试油实践中的试油 取得的成果，进一步拓宽了勘探领域。老井重新试油，使一批原来认为没有经济价值的稠油、特稠油、疏松砂岩以及低渗透油层通过新工艺、新技术的应用逐渐被挖掘出来，具有重要的地质意义和可观的经济效益。

Practice and Knowledge of Retesting for Old-Well

This paper fully and systematically analyses the reasons for low oil yield of numbers of heavy oil,super-heavy oil,loose sand reservoir and low permeability layers in Shengli oilfield.By use of countercheck results of old-wells,the industrial oil has been got in succession after retesting to these kinds of layers and in light of actual examples,testing technique and its results in old-wells have been introduced which expanded the exploration space further.It is retesting in old-wells that has excavated the heavy oil,super-heavy oil,loose sand and low permeability layers which are thought of no economic value by application of new technology and has an important geologic sense and a good economic performance.
