| 摘 要： | 针对渤中34油田油藏孔隙度渗透率比较低、温度比较高（大于120℃）的特点，结合储层伤害原因分析，根据室内试验结果，采用多氢酸体系对渤中34油田的油井进行酸化增产作业。通过对渤中34油田5口井（均为新井，完井后基本不出液）的酸化施工，酸化成功率达到100％，酸化后各井均达到甚至超过配产要求，这表明多氢酸体系对于高温低渗砂岩地层，能够有效地解除钻完井过程中造成的污染。与常规酸液体系相比，多氢酸体系具有明显的优势且效果明显，对于类似海上油田酸化有较强的借鉴意义。

| Abstract: | Based-on the analysis of reservoir damage and the results of lab experiment, five wells in BZ34 oilfield with low permeability and high temperature are treated by multi-hydrogen acid system. All of them get successful rate of 100%, and each of then meets or exceeds the allocated oil production after being treated. The results of treatments show that the multi-hydrogen acid system can remove the damages of drilling fluid and completion fluid effectively. In contrast with the conventional acid systems, the multihydrogen acid system has enormous advantages and it will be reference for this kind of offshore oitfields. |
