Abstract

本发明公开了一种二次采油法,包括如下步骤:将10-100ppm的聚乙烯基氨基双亚甲基磷酸和10-100ppm的二亚乙基三胺注入到含油地层中。本发明所述的二次采油法能有效解决由于油层堵塞而导致的采油效果差的问题。

Description

二次采油法
技术领域
本发明属于石油开采领域,具体地,涉及一种二次采油法。
背景技术
石油作为重要的矿产资源,非常珍贵。在石油开采过程中,为提高石油的采收率通常分三个阶段:一次采油,依靠地层的自然能量出油、采收率在30%以下;二次采油,采用注水、注气技术以补充油藏能量出油,采收率可提高至40-50%;三次采油,利用物理化学和生物学等强化开采剩余储量,采收率可提高至80-85%左右。而在二次采油过程中随着油层的堵塞等原因导致二次采油的效果不明显。
发明内容
本发明所要解决的技术问题是提供一种能有效解决由于油层堵塞而影响效果的二次采油法。
本发明解决上述问题所采用的技术方案是:
二次采油法,包括如下步骤:
将10-100ppm的聚乙烯基氨基双亚甲基磷酸和10-100ppm的二亚乙基三胺注入到含油地层中。
综上,本发明的有益效果是:本发明所述的二次采油法能有效解决由于油层堵塞而导致的采油效果差的问题。
具体实施方式
下面结合实施例,对本发明作进一步的详细说明,但本发明的实施方式不限于此。
实施例1
二次采油法,包括如下步骤:将100ppm的聚乙烯基氨基双亚甲基磷酸和100ppm的二亚乙基三胺注入到含油地层中。
综上,本发明所述的二次采油法能有效解决由于油层堵塞而导致的采油效果差的问题。
如上所述,可较好的实现本发明。
以上所述,仅是本发明的较佳实施例而已,并非对本发明作任何形式上的限制,依据本发明的技术实质,在本发明的精神和原则之内,对以上实施例所作的任何简单的修改、等同替换与改进等,均仍属于本发明技术方案的保护范围之内。
