Downhole tools for oilfield

The downhole tools from Tian Jin Aokai Oil Tools Co., Ltd. are mechanical and hydraulic devices designed for use in oil and gas well drilling, completion, and intervention operations. These include tools such as packers, centralizers, safety valves, and fishing tools, constructed from alloy steel and corrosion-resistant materials. Dimensions and pressure ratings vary by tool type, with standard operating pressures ranging from 5,000 psi to 20,000 psi and temperature tolerances up to 150°C.

Tool bodies are typically forged from 4140 or 4340 alloy steel, with surface treatments including nickel plating or hard chrome to resist abrasion and chemical corrosion. Thread types follow API 5CT or proprietary standards, with common configurations being 2-7/8 inch and 3-1/2 inch. Sealing elements use elastomers such as nitrile or fluorocarbon, rated for compatibility with drilling fluids and hydrocarbons. These materials and constructions are typical for tools used in both onshore and offshore environments.

These tools are used in well completion, workover, and production phases, particularly in sandstone and carbonate reservoirs. Buyers include drilling operators, well service contractors, and engineering firms in Southeast Asia, Africa, and the Caspian region. Trade terms are generally FOB Tianjin Port, with packaging in steel crates or wooden cases. MOQ varies by tool type, and custom tool designs are available upon request, but no lead time or pricing data is provided in the source.
