Understanding the Role of the Wireline Stop Ring in Drilling Operations
The Wireline Stop Ring is a crucial component in drilling operations, particularly in the oil and gas sector. This seemingly unassuming part of the machinery holds significant importance in overall operational efficiency and success.Get more news about Wireline Stop Ring,you can vist our website!
What is a Wireline Stop Ring?
A Wireline Stop Ring is used in conjunction with a core lifter. Its primary function is to prevent the core lifter from moving upwards when the core sample enters the inner tube. These stop rings are made of high-quality alloy steel and are specially heat-treated to increase strength, toughness, and wear life.
Application in the Industry
In the context of wireline fishing operations, a typical bottom hole assembly used to fish for wireline would consist of several components, including a rope spear, stop ring, safety joint (optional), bumper sub, oil jars, drill collars, accelerator jar, and fishing string.
In cased holes, it is always recommended to run a stop on top of the spear that is slightly less in outer diameter than the drift inner diameter of the casing. This is because if there is enough space, the line will get by the spear. A stop is never run in an open hole because of the possibility of the wire balling up above the spear, preventing re-entry of the spear into the casing.
Precautions and Safety Measures
Fishing for parted wireline with a spear is a dangerous operation and should only be performed by a fisherman experienced in this procedure. This is because the wireline can easily ball up so badly that it can cause the hole to be junked.
To avoid balling up the wireline, do not attempt to catch the wireline very far below the anticipated top of it. For example, if you caught the line with a spear and had a significant length of line above the spear, as you pulled the pipe up, that length of the line would ball up on top of the spear, causing it to stick.
Conclusion
The Wireline Stop Ring plays an indispensable role in drilling operations. Understanding its function and application can significantly enhance operational efficiency and success in the oil and gas industry.
