A few days ago, Shandong Rongcheng Inspection and Quarantine Bureau passed the inspection and 3 batches of tires with a value of 150,000 US dollars were exported to Sudan. This is the first time that the Weihai region has exported industrial products to the country since the pre-shipment inspection of industrial products from Sudan.
After the adjustment of the catalogue of legal inspections, the reduction of business contacts between export industrial product companies and inspection and quarantine institutions, the Rongcheng Bureau used portals and other methods to publicize the pre-shipment inspection bilateral agreements for Sudanese industrial products, and actively investigated the export of Sudanese industrial products manufacturing enterprises in the jurisdiction. , For the company to explain in detail the pre-shipment inspection inspection, inspection and inspection requirements, and remind the preparation. During this period, the Bureau organizes inspection personnel to study pre-shipment inspection regulations, collect Sudan industrial product inspection standards, and master pre-shipment inspection workflows to ensure the quality of work. The Bureau applies past classification management information for export companies, reviews the company's quality management system, audits test reports issued by CNAS accredited laboratories, insists on synchronization between production and inspection, synchronization between loading and inspection, synchronization of certificates and shipment, and before shipment The inspection work does not occupy the enterprise's logistics time, and realizes the optimization of the process and the maximization of the efficiency.
Drilling tool assembly (P, H, N and B)
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.
