Embodiment Construction

[0039] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0040] The electric submersible pump inspection device without workover machine of the present invention starts from changing the pump hanging mode of the current electric submersible pump, and changes the electric submersible pump to be hung on the middle and upper part of the oil pipe instead of being screwed on the lower end of the oil pipe. The pump inspection operation can be completed by using steel wire rope to lift out from the tubing and run into the electric submersible pump.

[0041] see Figure 1a-Figure 1j , Figure 2-Figure 9 , Figure 10a-Figure 10f , Figure 11-Figure 15 , Figure 16a-Figure 16c , Figure 17-Figure 19 , a pump inspection device for an electric submersible pump without a workover rig, comprising an oil pipe 100 and a well entry string, and the well entry string is arranged in the...

Abstract

The invention discloses a non-workover pump detection device for an electric submersible pump. The detection device comprises a well-in test string and an oil pipe, wherein the well-in test string is arranged in the oil pipe and comprises a hanger and an electric submersible pump, the hanger is fixed in the oil pipe and the electric submersible pump is suspended below the hanger. The pump detection device adopts the structure that the electric submersible pump is suspended in the oil pipe, so that the electric submersible pump can be taken out from the oil pipe as long as the well-in test string is taken out from the oil pipe when the electric submersible pump is required to be repaired and maintained, without dismounting the whole oil pipe.

Description

technical field [0001] The invention relates to the field of petroleum machinery, in particular to an electric submersible pump non-workover pump inspection device. Background technique [0002] In recent years, with the development of shallow oilfields in my country, the water content of the oil well production fluid is getting higher and higher as wells are drilled deeper, which makes the oil well production volume more and more large. In order to drill fewer wells and increase single well production, directional wells and horizontal wells have become the main well types in recent years. The electric submersible pump just adapts to the development trend of oil production with deep pumping, inclined wells and large displacement. With the increasing use of electric submersible pumps, the problem of electric submersible pump inspection has become increasingly prominent. In the current electric submersible pump system, the electric submersible pump and the cable are fixed at...
