The Qinjiatun Oilfield,a heterogeneity bedded fault block reservior located in the southern eastern slop of Lishu Fault Depression,Songliao Basin.Analysis of reservoir properties data,injection water quality data and mineral composition of QK4 well would provide conductive guidance for the Qinjiatun Oilfield.Therefore,to carry out this QK4 Well acidizing technology construction.Profile control is mainly to solve the contradiction between layers.By acidification to ease the Note does not feed the phenomenon,and greatly improving development effect to reach the purpose of stable production.
