据国外资料介绍,美国有很多公司从一九五二年就开始采用过油管射孔完井工艺。随着钻井和完井技术的发展,这种射孔工艺又不断地得到改进和发展。实践证明,它对提高试油速度、保护油(气)层、加快获得油(气)勘探成果,是一项重要的技术措施;对老油田查层补孔、挖掘潜力,也是一个很有效的手段。
According to foreign information, many companies in the United States have adopted pipe perforation completion technology since 1952. With the development of drilling and completion technology, this perforation process has been continuously improved and developed. Practice has proved that it is an important technical measure to improve the test oil rate, protect the oil (gas) layer, and speed up the oil (gas) exploration. It is also a very effective means.
