Relevant description of products:
Retrieve the inner tube with an overshot without lifting out the whole rods string to obtain the core, the wireline coring system lifts the underground core sample out of the borehole through the overshot to take back the entire inner tube and conduct sampling analysis. This improves productivity of the work site and guarantees safety of core sample during drilling down.
The system is realized through a fully independent inner tube. During its working, the inner tube does not connect with the overshot but locates at the bottom of the coring Drilling Rod directly (behind the coring drilling bit). An assembly device is installed on top of the inner tube, which includes coring and recycling functions. When the inner tube is full of core sample, the overshot is placed to the bottom from the borehole through a steel wire rope and lifted out by a winch. After the inner tube assembly is lifted to the surface, an empty inner tube is placed to the bottom of the hole to recover the drilling. This improves well drilling efficiency.
Our company provides core barrel assmeblies of different diameters to meet customers' demands. The wireline coring system is applicable for most drilling conditions and standard DCDMA hole sizes (B, N, H and P).
Currently, the company provides two models of wireline coring systems: double-tube and triple-tube
Core barrel assembly: It consists of inner tube and outer tube groups.
The inner part consists of the following parts: spearhead assemly, retrival components, core sample collection component, landing shoulder, stop ring and other parts.inner tube group, independent from outer tube group, collects core sample sample during well drilling.
The outer tube part consists of parts , which includes locking coupling, adapter coupling, outer tube, etc. The outer tube group that is kept at the bottom of the hole all the time holds the inner tube assembly during drilling.
The triple tube coring system AU3 has the same components as the dual-tube. And its interior has a third tube that is known as liner tube of the inner tube.
Liner tube of the inner tube is placed in the inner tube. The triple tube system can realize overall recovery ratio of core sample when drilling stratum with coal, clay or bigger crack. The liner tube or split tube keeps the core sample at its receiving status to collect or load and store easily.
Only N, H and P sizes are available for the triple tube coring system.
