摘要
为了研究低渗油藏注水井深度酸化-水力脉冲增注技术的研究情况以及实验匹配性。通过对延长油田某区块真实环境下岩心进行匹配性测试,运用多重复合型配方结合现场相关经验在子长N1-N21油藏属地所在的天然岩心实验环境下进行塔架搭设下进行相关酸化解堵实验设计,综合评定相关解堵效果和实验成效,然后进行配方的升级与进一步优化。进行相关研究,最终得出相应实验结果。
In order to study the deep acidification-hydraulic pulse injection technology and experimental matching of injection wells in low permeability reservoirs.Through matching test of cores in real environment in a block of Yanchang Oilfield,the relevant acidizing plug removal experiment design was carried out under the natural core experimental environment where Zichang N1-N21 reservoir is located by using multi-repetitive formula combined with relevant field experience,and the related plug removal effect and experimental effect were evaluated comprehensively,then the formula was upgraded and further optimized.Relevant research is carried out,and the corresponding experimental results are finally obtained.
