摘要(Abstract)：

针对金 侧平 6井的特点 ,分析了造成水平井污染堵塞的原因。通过室内实验确定了具有综合解堵作用的酸化解堵配方。该配方由多元混合酸和多种添加剂等组成 ,主要对泥浆污染和原油乳化等堵塞具有较强的解除能力 ,另外对油污、蜡质、胶质、沥青质、机械杂质等也具有较好的溶解、降粘、溶蚀作用 ,可达到综合解堵的目的 ,同时也确定了现场实施的配套工艺技术。因该井的水平井段长 ,酸化时所需酸液量大 ,为达到最佳的解堵效果及降低酸液用量 ,采用暂堵转向技术来达到均匀酸化的目的。经过对该井的现场施工 ,取得了明显的增油效果 ,为油田今后水平井酸化施工提供了成功的经验。
According to the characteristic of Well Jin Ceping 6 and the reason of pollution and plug, this paper performs a laboratory experiment to analyze the acidizing displug formulation after pilot operation. This formulation is composed with multicomponent mixed acid. It has the capability of displugging of mud pollution and oil emulsification, and can be also used in the dissolution and viscosity reduction of wax, gel, asphaltene and mechanic impurity. it gets a stimulation effect and provides successful experience for the acidizing of horizontal wells.
