What is Core Barrel?
Core drilling is one of the most advanced technology equipment used in deep drilling operations worldwide. During drilling operations underground, core sampling operations from the cut formation are called core drilling, and the hardware that performs this process is called core barrel. When the drilling works are finished, the carotiders that must be kept in their original boxes must be kept regularly and cleaned, and an archive indicating which type and amount of core is taken. should be used with the system.
Core Types
a) Normal core barrels: normal core barrels are available in two types.
1) Two-tube core barrel: The two-tube core barrel is a commonly used type of rolled or laminated core barrel consisting of an outer tube to which it is attached and an inner tube that maintains the core. While the drill is progressing during the drilling process, the core taken starts to rise in the tube, there is a core holder at the lower end of the core so that the received core does not fall due to shaking. The average efficiency of this type of carotid is around 65% -70%.
2) Single tube core barrel: During the core removal, the normal progress is stopped at the desired depth and the core is released from the pipes (rod), while the core drill comes out of the gap in the middle of the actual drill and then the core is removed and is pulled up through the pipe using a special cable and small Coring is taken in sizes.
b) Horizontal core barrels: They are classified as impact, gun, hydraulic and periodic horizontal core barrels.
c) Diamond-tipped core barrels: They are used to get high efficiency in very hard formations because they are different from other normal core barrels, because they are diamond-tipped and they show up to 100% performance. Core drilling equipment, which is an important drilling equipment in drilling works, should be cleaned very well after drilling and it should be listed with which end the cores taken are from which depth.
Wireline core barrel
Wireline core barrel is a type of core barrel used in drilling work, inner tube head and inner tube are the most important parts of this equipment. The dimensions and types of threads on both sides of the inner tube are the same, and both sides of the inner tube are made of male threaded cold drawn tubing. Since the core taken during drilling will corrode the top of the inner tube much more quickly, changing the inner tube from time to time will prolong the life of the material. The ring slot where the ring holding the core taken during drilling is placed is located at the bottom of the inner tube. The ring can be placed in this slot above the area where the ring is placed in the ring seat, and the ring ring prevents the core taken with the ring from being drawn into the inner tube. The inner tube head inside the inner tube pipe is the most important part of the wireline core barrel system and contains some systems. When the inner tube is placed inside the outer tube, the latch system on the inner tube is locked to the armor on the outer tube, and its retraction is prevented when the inner tube is retracted, and when the work ends, the lance-shaped part on the head is pulled out by means of overshot and the latches are retracted and closed so that the inner tube passes through the tubes. taken with ease.
Overshot
Overshot is a drilling equipment used in the areas where drilling applications are carried out with the help of drill or cutting tools and the material obtained as a result of drilling in the region and used to pull the spearhead ends at the end of the core. There are types suitable for underground and above ground drilling applications and they are manufactured using high quality raw materials.
Flat Tool Core Barrel
This type of core barrels, which are preferred for drilling studies that require no more depth and for ground surveys, are classified as single tube core barrels, T double tube core barrels according to the core feature desired to be obtained. It is generally recommended to use T6 S type double tube core barrel to take intact samples. All materials and drilling equipment used in drilling works should be used carefully and by expert staff, as many equipment should be of high technology and precision, and maximum attention should be paid.
