Description
This kind of Drill pipe casing tube is able to stabilize the borehole during the drilling process.The drill casing has two different functions: firstly, it can help to prevent the well walls from collapsing, as well as to control the formation fluids. Secondly, it enables both well control equipment and downhole equipment to more easily achieve their functions.
Besides, it suits a wide variety of well diameters as well as different material grades. It is resistant to chemical erosion, and it can withstand various external forces, like collision, bursting, tensile strength, etc.
The specifications of the casing tubes vary according to different drilling technologies. And the connection mode can be self-connection as well as connected through joints. The materials of drill pipe are generally above the DZ50 level.
Regarding the packaging, slotted steel framing is utilized. There are 30 to 40 tubes per bundle, and each bundle need one frame.
Note:
1.During the operation process, workers need to check whether there are any damages at the tread connection point of the casing tubes. If there are any damages, please replace it immediately so as to avoid tripping when using this casing tube.
2.Suitable casing tube is always required, which can prevent it from being hit or friction.
3.When connecting the casing tubes, thread oil is quite necessary.
