Spiral Grapple - Downhole Debris/Tool Retrieval: When fishing out stuck or fallen cylindrical tools (e.g., broken drill pipes, collars) or irregular debris in the wellbore. - Milling & Fishing Combined Operations: Working with milling tools to grip and lift fragmented or partially milled objects after initial debris breaking. - Wellbore Cleaning in Complex Wells: Used in deviated or horizontal wells to retrieve objects that traditional fishing tools may struggle to secure.
The Sliding Block Spear is an internal fishing tool used for fishing fallen objects that are generally used in oil perforation process, such as drill pipe, tubing, wash pipe, liner, packer, water distributor, etc. It can also be used for the reversing of stuck fallen objects and it can be used in conjunction with other tools such as jar and back-off tool.
The gear wheel of a roller reamer is mainly used in the following scenarios: - Oil and gas well drilling: Installed on the roller reamer, it helps transmit torque during the drilling process, enabling the reamer to rotate smoothly, expand the borehole, and maintain the wellbore diameter to ensure the normal progress of drilling operations. - Underground construction engineering: Applied in underground projects such as tunnel boring, it assists the reamer in cutting and reaming the stratum, improving construction efficiency, and ensuring the stability and accuracy of the borehole.
XINRUIDE wear sub consists of a highly wear rubber sleeve,a metal stiffening liner and a sub body.The rubber sleeve is installed in the middle of sub body and some clearance is given to allow sleeve to rotate freely.The rubber sleeves are made of rubber mixtures with good wear resistance.
Application Scenarios - Retrieving Cylindrical Downhole Tools: Used to fish out stuck or broken drill pipes, collars, or stabilizers with regular outer diameters in the wellbore. - Handling Smooth-Surfaced Objects: Ideal for grabbing tools or debris with smooth, uniform surfaces that are difficult for other grapples to secure. - Wellbore Cleaning in Vertical/Moderately Deviated Wells: Efficiently operates in relatively straight or slightly deviated wells to recover fallen objects.
Drilling Roller Reamers are designed for reaming and stabilization in any type of formation.All parts of the tool are made of special alloy steel and heat treated for hardness.Drilling crews can easily replace any part in the field without using any special tools.
Kelly is main driver of the whole drill string.It transmits torsional energy from the rotary table through the drill string to the bit at the bottom of the hole.XINRUIDE Kelly is a long square or hexagonal,precision machined heavy steel bar that is supported by the swivel through the rotary table and is connected to the first joint of drill pipe in the drill string.
The Skirted Junk Mill is designed for milling tubular fish,either inside casing or in open hole.Should the fish be plugged,it is far better to use a shoe-type guide with a flat mill to avoid side tracking.
The Pilot Mill is best used for milling stuck tubular tools,such as liner,liner hanger,wash pipe,rotary shoe or drill pipe.The pilot assembly keeps the tubular tools in a centered position,while the milling blades mill the product away.
The Flat Bottom Junk Mill is the most commonly used milling tool. The Flat Bottom Junk Mill is designed to mill a wide variety of junk such as squeeze tools, packers, tubing, bridge plugs and similar objects.
Bladed Junk Mill is dressed with high-quality tungsten carbide to ensure optimal performance in all applications.They are suitable for all types of general junk milling,as well as for removing packers,retainers,and squeeze tools.
The String Mill is designed to cleancasing and whipstock windows.Its short leading and trailing angles,allow the mill to clean "bird nest"and other obstructions in the string,while thebottomhole tool is milling.This string mill assures that the milled section maintains full gage.
