摘要
目前油田常用的几种封隔器结构都比较复杂,在实际应用中坐封和解封存在着一些问题。为此,研制了一种新型自封式封隔器,采用自封原理,取消了封隔器的坐封、解封机构和相应的操作。现场试验表明,这种封隔器结构简单、使用可靠,具有广泛的应用前景。
There are types of packer whose structure is complex at present. And it needs a lot of condition when the packer set and unset so there are a lot of problems in practice application. We designed a new type packer for it. It used auto set principium and it avoided the setting of packer, the structure of unsetring and so, according to the practical application, this type packer＇s effect of application is good because of its simple structure and reliable capability.
