Problems solved by technology

[0002] During the operation of electric pump wells, when lifting and lowering the electric pump string, the clips of the electric pump often fall off more or less due to reasons such as casing track, dogleg degree, speed of lifting and lowering the pipe, and improper derrick. The annulus fell into the casing, some got stuck in the gap between the casing collars, some fell on the casing change, and some fell on the lower fish head. Multiple operations are bound to accumulate more and more for future measures. It brings hidden dangers and affects the salvage of fallen objects

Embodiment Construction

[0012] The present invention provides the following technology including the following processing steps:

[0013] The cable clip anti-dropping device includes the electric pump clip anti-dropping device, which is mainly composed of the upper joint, the center pipe, the salvage blue, the drain hole, and the lower joint. ①Ensure that there is enough space in the sedimentation cup. ②When the wellbore is waxed, the salvage blue will overflow from the drain hole after the scraping is full, so as to ensure the normal start of the pipe string. ③Drain the well fluid in the process of pulling up the pipe string, and there is an environmental protection operation.

[0014] (2), the upper connector: it is mainly connected to the motor, which is a 27 / 8 male buckle.

[0015] (3) Salvage blue: There are two specifications, the other is Φ112mm. ①Fix the cable clips that have fallen off from the upper part. ②The opening is an inner chamfer, which can play the role of scraping wax for the ...

Abstract

The invention discloses a cable clip anti-drop device. The cable clip anti-drop device includes an electric pump clip anti-drop device mainly composed of an upper connector, a central tube, a salvagebasket, a drainage hole and a lower connector. The anti-drop device is connected to the tail end of an electric pump motor and is driven into a well together with an electric pump production pipe string, in the process of driving the electric pump pipe string, a cable clip is unfastened and falls due to a sleeve trajectory and other reasons, the cable clip can fall to the tail of the motor along with an annular space of an oil sleeve, the annular space is increased (phi107 mm is reduced to phi60 mm) at the time, and the clip is moved and falls toward the annulus center until the clip enters the salvage basket.

Description

technical field [0001] The present invention relates to cable equipment, in particular to a cable clip preventing device. Background technique [0002] During the operation of the electric pump well, when the electric pump string is tripped, the electric pump clip is often dropped more or less due to the casing trajectory, dogleg degree, speed of tripping and tripping, and improper derrick. The annulus falls into the casing, some are stuck in the gap of the casing coupling, some fall on the change of the casing, and some fall on the lower fish head. After repeated operations, it is bound to accumulate more and more for future measures. It brought hidden dangers and affected the salvage of the lower animals. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a device for preventing cable clips from falling out. [0004] In order to achieve the above purpose, the technical scheme adopted in the present invention is: the cable clip anti-dro...
