Alloy Steel Wireline GR Type Pulling Tool QLS BLQJ Connection

Ⅰ. Introduction

GR Type pulling tool is composed of GU shear up adaptor (upward shear adaptor) and GS pulling

tool (without shear pin), which can be released by upward shear. It is usually used for fishing

lock mandrel, packers ,and bridge plugs with internal fish necks.

GR Pulling tool is used to engage and pull sub surface flow control devices that are fitted with an Internal Fishing Neck

Designed to be used when downward jarring is required on the sub surface device prior to pulling

Ⅱ. Technical parameters of common specifications

Technical parameters can also be according to user requirements

III. Structural characteristics:

1. GR Type pulling tool is mainly composed of GS pulling tool (1) and GU Shear Up Adaptor (2), as

shown in the attached assembly drawing.

2. During fishing operation (refer to GS assembly drawing), when the fishing claw (8) touches the

mouth end of the inner fishing neck, it will retreat and fall into the slightly smaller diameter of

the core (9) and be retracted; When the fishing claw (8) completely enters the inner fish neck,

the fishing claw (8) is immediately opened to catch it under the thrust of the compression

auxiliary spring (5). If the tool is blocked upwards, it can be shaken off.

3. Fitted with Industry standard connections and fishing necks
4. Jar up to release functionality

5. Effective jar up release functionality

IV.Maintenance

1. After the tool is disassembled, check the damage of each component and replace the

damaged parts.

2. When assembling, apply a thin layer of grease on the thread surface.

3. After assembly, the fishing neck is attached with thread protector and marked for later use.
