一种潜油电泵同井采注管柱装置及方法
摘要：
本发明涉及一种潜油电泵同井采注管柱装置及其采注方法，其特征在于：由上至下依次设有滤砂管(2)、测试短接(4)、筛管(6)、第一封隔器(5)、倒置水泵(11)、丢手接头(13)、第二封隔器(14)、出水管(15)，其中滤砂管(2)、测试短接(4)、筛管(6)依次连接，筛管(6)穿过第一封隔器(5)，筛管(6)的出水口位于第一封隔器(5)的下方，倒置水泵(11)的吸水口(10)与环腔连通，所说的环腔为第一封隔器(5)和第二封隔器(14)之间的环腔；倒置水泵(11)的出水口接丢手接头(13)，丢手接头(13)穿过第二封隔器(14)，丢手接头(13)的出水口(15)位于第二封隔器(14)的下方。
摘要（英）：

The invention relates to an electric submersible pump same-well production-injection pipe column device and a production-injection method of the device. The device is characterized by sequentially comprising a sand filtering pipe (2), a test short connector (4), a sieve pipe (6), a first packer (5), a reverse water pump (11), a release sub (13), a second packer (14) and a water outlet pipe (15) from top to bottom, wherein the sand filtering pipe (2), the test short connector (4) and the sieve pipe (6) are sequentially connected; the sieve pipe (6) passes through the first packer (5); a water outlet of the sieve pipe (6) is positioned under the first packer (5); a water suction opening (10) of the reverse water pump (11) is communicated with an annular cavity; the annular cavity refers to an annular cavity between the first packer (5) and the second packer (14); a water outlet of the reverse water pump (11) is connected with the back-up sub (13); the back-up sub (13) passes through the second packer (14); and a water outlet (15) of the back-up sub (13) is positioned under the second packer (14).
