适用人工举升的电潜泵生产管柱
摘要：
一种适用人工举升的电潜泵生产管柱，包括：套装在套管中的的油管、安装在油管上的Y接头、与Y接头相连的电潜泵、由上至下依次安装在Y接头上的带孔管或滑套、定位密封、插入密封、生产滑套、防砂封隔器，其中，在电潜泵的上部和Y接头之间安装一井下安全阀，该井下安全阀通过液控管线与地面液控站相连，由地面液控站提供压力控制。本实用新型将井下安全阀安装在电潜泵的上部，并使井下安全阀通过液控管线由地面液控站提供压力控制；由于去掉了电缆封隔器，不仅大大降低了上提管柱时的吨位重量，而且，在洗、压井时，还使液体排量通畅，提高了洗、压井的效率。
摘要（英）：

The utility model discloses an electric submersible pump production string suitable for manual lifting. The electric submersible pump production string comprises an oil pipe sleeved in a sleeve, a Y joint arranged on the oil pipe, an electric submersible pump connected with the Y joint, and a pipe or a sliding sleeve with holes, a positioning seal, an inserting seal, a production sliding sleeve and a sand control packer which are sequentially arranged on the Y joint from top to bottom, wherein an underground safety valve is arranged between the upper part of the electric submersible pump and the Y joint and is connected with a ground hydraulic control station through a hydraulic control pipeline, and the ground hydraulic control station provides pressure control. According to the electric submersible pump production string, the underground safety valve is arranged on the upper part of the electric submersible pump and the ground hydraulic control station provides pressure control on the underground safety valve through the hydraulic control pipeline; because a cable packer is eliminated, the tonnage for lifting the string is greatly reduced; moreover, during well washing and well killing, liquid is discharged smoothly and the efficiency of washing and killing a well is improved.
