Embodiment Construction

[0007] The present invention will be described in further detail below in conjunction with the accompanying drawings: Referring to the accompanying drawings, the present invention consists of a shaft 3 and a basket, and is installed on the bottom of the shaft 3 . Basket is made up of basket body 4 and basket seat 5, and basket body 4 is connected and fixed with basket seat 5. The basket body 4 is a tubular body, the diameter of the opening at the upper end is larger than the diameter of the basket, and the opening at the upper end is processed with a plurality of vertical slots, so that the diameter can be elastically adjusted, and can be attached to the inner wall of the casing to achieve the best capture Effect. Holes or gaps are distributed in the basket at the bottom of the vertical slit, so that the well fluid flows without resistance, and its bottom is connected and fixed with the basket seat 5. The basket seat 5 is provided with an inner hole, and the inner hole cooper...

Abstract

The invention discloses a trapper silo fallen object trapper in oil industry, applied to oil well with electric submerged pump. It also can be applied to other producing pipes of other oil well and the matching well repairing work, in order to trap the silo falling object. The invention is made up of spindle pole and basketry, the basketry is arranged under the spindle pole. It is arranged under the electric pump ground or the bottom of the silo well pipe, they are put into the well at the same time. When pulling the electric submerged pump upwards or other well pipes, the end part of basketry traps the falling small objects such as cable clamper or mantle with a large aperture diameter, in order to clean the well bottom, eliminates future trouble, reduces the production cost.

Description

technical field [0001] The invention relates to downhole oil production equipment in the petroleum industry, in particular to a downhole falling object catcher, which is suitable for wells using electric submersible pumps for oil production and used in conjunction with the electric submersible pumps. It can also be used in other oil wells to capture and collect well falling objects. technical background [0002] In the oil production process of the electric submersible pump in the petroleum industry, when the electric submersible pump is operating in the oil production well, affected by the quality of the tool, the operation reason, etc., it often encounters the problem that the cable clamp and the shield fall off the well. Since the cable clips are made of high-hardness alloy materials and have irregular shapes, it is very difficult to salvage after falling into the well, which brings great difficulties to the removal of bottom-hole grit, the extraction of downhole tools an...
