摘要： A downhole pumping assembly has a tubing string with plural barrels which are arranged in-line with the tubing. The tubing string has a seating location adjacent to each barrel. A standing valve arrangement, which includes a standing valve and a seating device, is located with the standing valve adjacent to the lower end of one of the barrels. A plunger has a traveling valve that is located for reciprocation within the one barrel. The plunger has a clearance with each of the barrels so as to form a fluid seal. The plunger reciprocates inside the barrel so as to lift fluid to the surface. Over time, the barrel will exhibit wear. Instead of pulling the entire tubing string to replace the barrel, the standing valve and the plunger are relocated to one of the other barrels located in the tubing string and reciprocation is resumed to resume pumping.

摘要翻译： 井下泵送组件具有多个管的管柱，其与管道成一直线布置。 管柱具有邻近每个筒的座位。 一个立式阀装置，其包括一个立式阀和一个就座装置，其中立式阀邻近一个桶的下端。 柱塞具有位于一个桶内往复运动的行进阀。 柱塞与每个筒具有间隙，以形成流体密封。 柱塞在筒内往复运动，以将流体提升到表面。 随着时间的推移，桶将会穿着。 代替拉动整个油管柱以更换机筒，将立式阀和柱塞重新定位在位于油管柱中的另一个管中，并且往复运动恢复以恢复泵送。
