为进一步提高靖边油田Y8Y9油井酸化效果,降低成本,增加效益,针对储层特征的实际情况,通过土酸溶蚀试验,缓蚀性能试验,从而优选出适合靖边油田Y8Y9油层的酸化用液配方:12%HCl+3%HF+2～3%甲醛+3%冰醋酸。
In order to further improve the acidizing effect of Y8Y9 oil wells in Jingbian Oilfield, reduce costs and increase benefits, according to the actual situation of reservoir characteristics, the acidification solution for Y8Y9 oil layer of Jingbian Oilfield is optimized through the test of soil acid corrosion and corrosion inhibition : 12% HCl + 3% HF + 2-3% formaldehyde + 3% glacial acetic acid.
