Product Name:Slip, drill pipe slip
Product Model:
Place of Origin: Shanxi, China
A drill pipe slip is a tool used to catch and suspend drill strings or casing strings during tripping in and out of the wellbore. It is placed between the drill pipe, casing, or tubing and the large square bushings to grip and hold the drill string, casing string, or tubing string inside the wellbore, preventing them from falling into the wellbore. This improves the efficiency of tripping and ensures the safety of drilling operations.
Types:
There are several types of slips, including:
•
Drill Pipe Slips: Specifically used for drill pipes.
•
Drill Collar Slips: Used for drill collars, which are the main components of the bottom hole assembly and have significant weight and rigidity.
•
Casing Slips: Used for casings, which are primarily used to stabilize the wellbore and prevent blowouts.
•
Manual Slips: Require manual operation by workers, which can be labor-intensive.
•
Semi-automatic Slips: Offer a certain degree of automation but still require manual assistance.
•
Fully Automatic Slips: Are completely automated, reducing labor intensity and improving work efficiency.
Applications:
Slips are used in various petroleum operations that require catching and suspending tubulars:
Drilling Operations: During drilling, slips are used to catch and suspend drill pipes, drill collars, powered drilling tools, casings, and other tubulars being run into the wellbore to ensure smooth drilling operations.
Well Logging Operations: In well logging operations, slip fishing tools are often used to retrieve fallen logging instruments from the wellbore. For example, the CDL slip fishing tool has been widely used in fishing operations for fallen instruments in oil and gas regions such as Sichuan-Chongqing, Changqing, Tarim, and Qinghai.
Other Operations: Slips are also used in other petroleum operations that require catching and suspending tubulars, such as completion operations and workover operations.
As an important tool in petroleum drilling operations, slips play a crucial role in drilling and well logging operations. By using slips appropriately, the efficiency of tripping can be improved, the safety of drilling operations can be ensured, and labor intensity can be reduced, thereby promoting the sustainable development of the petroleum industry.
