摘　　要：富台油田下古生界潜山油藏储层基质渗透率低、裂缝和溶蚀孔洞发育、普遍受到污染,采用酸化压裂措施改造油层以增加油井产能。根据地层测试资料和压力曲线特征,结合储层静态资料指导选择酸压井层及酸压规模,进行常规酸预处理。采用胶凝酸和压裂液交替注入的闭合酸化工艺,增产效果显著,对改善该区深井、超深井的潜山储层的裂缝导流能力、提高油层渗透率和解除油层的污染状况有明显效果。The matrix of down-Palaeozonic burial hill reservoir in futai oilfield has low permeability and the develop of crack and dissolved hole is always polluted which is needed the treatment of acid and fracture to increase production of oil well. According to feature of testing data and pressure curve and combing with static data of reservoir to induct selecting fractured layer and fracture scale and conventional pre-treatment with acid, the result is obvious by using close acid tech with alternation injection of gelling acid fracture fluid. The acid and fracture tech to this reservoir has a good result for improving fluid diversion capacity of crack in burial hill formation of deep and super deep wells in this district, raising up formation percolation and relieving polluted station of oil layer.
