Series 10 Overshot is Internal Fishing Specialist Series 10 Overshot has Dual Grapple System Series 10 Overshot has Guide-Assisted Accuracy Series 10 Overshot, Single-direction rotation streamlines operations in high-stress oil tools environments.
The Concave Junk Mill is designed for milling bit cones and other loose objects.The Concave Junk Mill keeps the fish in a centralized fix location under the mill for greater milling effectiveness.
XINRUIDE Series 150 Releasing and Circulating Overshot is an external fishing tool for engage, pack off and retrieve tubular fish, especially for fishing drill collar and drill pipe. The grapple of the overshot can be designed for different sizes of fish, so one overshot can be dressed with different size of grapple components for fishing different sizes of fish.
Float valve Sub is an important tool in petroleum exploration and drilling engineering.The float valve sub is connected at upper part of drill bit.The float valve sub is near the bit connecting thread.The float valve sub can also be used at different necessary position of drill string when required.The main application is,when connected with single piece pipe,it prevents mud from coming in and up blocking the hole.When blowout takes place,blowout in drill string will be avoided because nozzle is closed automatically by valve cap of the float valveassembly.
1. By Pass Valve is Emergency Circulation Path - Activates when "bit bore is blocked" during kicks, creating immediate fluid diversion - Restores circulation within 2-5 minutes of activation 2. By Pass Valve is Ball-Activation Mechanism - Triggered by dropping steel/nylon ball ("discharge Kelly and drop in a steel ball") - Ball retainer system guides projectile to shear assembly
1. High-Quality Materials & Standards Compliance – Our drill pipes are manufactured in strict accordance with SY/T5561 and API Spec 5DP standards, ensuring superior performance in demanding drilling operations. 2. Enhanced Durability – Featuring wear-resistant hardfacing on the box-end connection, our drill pipes minimize casing and drill pipe wear, extending service life. 3. Precision Engineering – Threads at both ends undergo phosphate coating and are fitted with thread protectors, while optional cold rolling treatment at thread roots enhances fatigue resistance. 4. Rigorous Testing – Each drill pipe undergoes makeup/breakout testing to guarantee reliable connections under high torque and pressure.
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.
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.
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.
