摘要
从理论上分析研究了增注液态CO2 对酸化效果的影响 ,并结合现场施工实践 ,分析对比关X1井两个油层的酸化工艺和酸化结果 ,证明CO2 助排技术应用于低压、低渗油层可以有效地提高酸化效果 ,提高试油和对油层评价的准确度和可信度。
The paper analyzes and studies the influence to acidizing effect by increasing injection liquid state CO 2 through theory.Combining with field ope ra tion examples and comparing acidizing technology and its results of two oil laye rs in Guan X1 well,it proves that CO 2 clean up technology could raise acidizin g result effectively which is applied in low pressure and low permeability oil la yer,increase accuracy and liability of test and reservoir evolution.
