| 摘 要： | 华港104-P2水平井在钻井及完井过程中受到的污染严重，采取一系列增产措施后，效果不理想。针对上述问题，对该井堵塞原因及前期增产措施进行了总结分析。为了达到向油层不同部位渗透的酸液量基本相等的目的，在分析了泡沫酸解堵机理及室内实验的基础上，提出了酸液拌空气注入的施工方案。通过现场应用，取得了较好的效果，为水平井解堵提供了有效方法。

| Abstract: | In order to resolve the pollution of Huagang 104-P2 well which was polluted during drilling and well completion, measures have been taken, however, the result was not good. In view of the above problems, the bloicking reasons and stimulation treatment of this well are summarized and analyzed in this paper. In order to guarantee the quantity of acid seeping to different area of oil layers equally, on the basis of analyzing the plug removal mechanism of foamed acid and indoor experiment, a construction scheme of injecting acid mixed with air was promoted. This method has acquired good effect according to the field application, which provides a way to remove the block of horizontal well. |
