One end of the inner hole has a large diameter and the other end has a small diameter, and the inner hole The large-diameter end of the hole is far away from the spring, the small-diameter end of the inner hole is close to the spring, and a Ver ball is arranged in the Ver seat. The utility model is connected to the lower end of the hydraulic compression packer to run a pipe string into the well. When the packer is set, the multifunctional bottom seat is closed, and the packer is set for pressure. After the packer is set, the multifunctional The pin of the functional ball seat is cut off, and when the pressure is released, the ball seat pops out of the sealing sleeve under the elastic force of the spring, and the multifunctional ball seat is not sealed, which effectively avoids the influence on the oil well pump.
Description
技术领域 technical field
本实用新型涉及抽油泵带水力压缩式封隔器卡封采油工艺，属于油井设备技术领域。 The utility model relates to an oil production process of an oil well pump with a hydraulic compression packer clamping seal, and belongs to the technical field of oil well equipment.
背景技术 Background technique
底部球座用于抽油泵带水力压缩式封隔器卡封采油工艺中，连接在水力压缩式封隔器下端一趟管柱下入井中。目前的底部球座是单流阀，在抽油泵带水力压缩式封隔器采油工艺中，封隔器坐封后，底部球座继续单向密封，和抽油泵固定球座形成双固定球座，影响抽油泵正常工作。 The bottom ball seat is used in the oil recovery process of the oil well pump with hydraulic compression packer clamping, and is connected to the lower end of the hydraulic compression packer to run a string into the well. The current bottom ball seat is a check valve. In the production process of oil pump with hydraulic compression packer, after the packer is set, the bottom ball seat continues to seal in one direction, and forms a double fixed ball seat with the fixed ball seat of the oil well pump. , affecting the normal operation of the oil well pump.
发明内容 Contents of the invention
本实用新型的目的是为了克服现有技术的不足，提供一种多功能底部球座，即能对封隔器坐封，又能有效避免双固定阀对抽油泵的影响。 The purpose of the utility model is to overcome the deficiencies of the prior art and provide a multifunctional bottom ball seat, which can not only set the packer, but also effectively avoid the influence of the double fixed valve on the oil well pump.
本实用新型的目的是这样实现的：一种多功能底部球座，包括密封套，在密封套的一端内侧配合设置凡尔座、另一端内侧一体设置凸台，凡尔座通过销钉与密封套连接，在凡尔座与凸台之间设置弹簧，在凡尔座上轴向设置内孔，内孔的一端直径大、另一端直径小，并且内孔的大直径端远离弹簧，内孔的小直径端靠近弹簧，在凡尔座内设置凡尔球。 The purpose of this utility model is achieved in this way: a multi-functional bottom ball seat, including a sealing sleeve, a valve seat is arranged on the inner side of one end of the sealing sleeve, and a boss is integrally arranged on the inner side of the other end, and the valve seat is connected with the sealing sleeve through a pin. Connection, a spring is set between the valve seat and the boss, and an inner hole is arranged axially on the valve seat. One end of the inner hole has a large diameter and the other end has a small diameter, and the large diameter end of the inner hole is far away from the spring. The small-diameter end is close to the spring, and a Ver ball is arranged in the Ver seat.
本实用新型连接在水力压缩式封隔器下端一趟管柱下入井中，封隔器坐封时，多功能底部求座关闭，封隔器起压坐封，封隔器座封后，多功能球座销钉被剪断，泄压时凡尔球座在弹簧的弹力作用下弹出密封套，多功能球座不密封，有效避免了对抽油泵的影响。本实用新型即能对封隔器坐封，又能有效避免双固定阀对抽油泵的影响。 The utility model is connected to the lower end of the hydraulic compression packer to run a pipe string into the well. When the packer is set, the multifunctional bottom seat is closed, and the packer is pressure-set and sealed. After the packer is set, multiple The pin of the functional ball seat is cut off, and when the pressure is released, the ball seat pops out of the sealing sleeve under the elastic force of the spring, and the multifunctional ball seat is not sealed, which effectively avoids the influence on the oil well pump. The utility model can not only set and seal the packer, but also effectively avoid the influence of double fixed valves on the oil well pump.
为了保证密封性，在所述密封套与凡尔座之间设置密封圈。 In order to ensure the tightness, a sealing ring is arranged between the sealing sleeve and the valve seat.
为了便于密封套与其它部件连接，在所述密封套的一端设置外螺纹、另一端设置内螺纹。 In order to facilitate the connection of the sealing sleeve with other components, one end of the sealing sleeve is provided with an external thread, and the other end is provided with an internal thread.
