To solve the problem of setting of hydraulic packers in horizontal holes,a ball-and-seat and a setting ball plugis designed for two setting technologies respectively.

针对水平井液压封隔器不能实现坐封 ,采用盲孔球座不但不能洗井 ,还会在打压过程于油管内形成气塞 ,影响坐封效果 ;采用盲孔球座和分流开关组合方式又存在水击和不能洗井的问题 ,提出了单流阀坐封球座和坐封球塞 2种水平井液压封隔器坐封工艺 ,并研究设计了单流阀球座和坐封球塞。

The pulg has characteristics of removable, settingprecision, preventing block and preventing adhesion,and can build multiform plugging pipe, which can solve the problem above and reduce the venture of ash squeezing and plugging,thus saving the work time.

该桥塞具有可取、坐封准确、防卡、防粘等特点,并形成了多种井下封堵管柱,能够解决挤水泥封堵过程中出现的上述问题,并且降低了挤水泥封堵风险,缩短了施工周期。

The success or failure of well testing operation is determined by settingsituation of the slip-type packer or not.

卡瓦封隔器能否坐封直接决定测试施工的成败。

Working mechanism and characteristics of both mechanical and hydraulic settingof fracturing string are introduced respectively.

根据封隔器坐封方式的不同,介绍了机械坐封、液压坐封压裂管柱的工作原理及特点;对不同坐封方式下的压裂管柱进行力学分析,建立了坐封前、坐封过程及压裂过程的力学模型。
