ＺＦ皮碗封隔器以其皮碗的金属骨架结构来提高封隔器的承压能力，密封是靠皮碗与套管内壁的过盈和井内压差来实现，所以所需零部件少，加工组装方便。修井时可直接上提起出管柱，不需要附加其它动力设备。该封隔器与洗井开关、ＳＭ水力锚、循环开关等井下工具配套可组成新颖实用的泵上洗井管柱和酸化注入管柱，这两种配套管柱经现场１６井次试验证明了其技术的可靠性。对于皮碗上部出砂严重的井，为防止起出困难，应慎用该型封隔器。
ZF Cup Bowl packer with its metal structure of the bowl to improve the packer pressure capacity, the seal is by the bowl and casing wall interference and well pressure difference to achieve, so the required parts and components less processing Easy to assemble. Workover can directly lift the column, do not need to attach other power equipment. The packer is matched with downhole tools such as well washing switches, SM hydraulic anchors and circulation switches to form a novel and practical pumping well washing well string and an acidification injection string. The two matched casing strings are verified by 16 well tests in the field The technical reliability. For the wells in the upper part of the sand well, in order to prevent the difficulties, should be used with caution.
