Manufacturer of downhole accessories for CNOOC and PetroChina

Dingding Titanium Rod allows us to achieve more accurate data and more stable instruments under the "hell" working conditions of 175 ℃ high temperature and 140MPa high pressure!

We supply core logging components to CNOOC. In the past, traditional materials were a major challenge in deep and ultra deep wells

Insufficient pressure resistance: In ultra-high pressure environments above 140MPa, the shell is prone to slight deformation, resulting in data drift of internal precision sensors;

High temperature creep: Under continuous high temperature of 175 ℃, the material strength decreases and there is a risk of failure;

Corrosion and magnetic interference: The complex sulfide and halide environment underground exacerbates corrosion, and the magnetic properties of materials directly interfere with the accuracy of electromagnetic logging signals.

Since switching to the TC18/TC11 high-strength and high toughness titanium alloy rods from Dingding Titanium Industry in all categories, these problems have been easily solved:

Strong and resilient guarantee: Its titanium rod has a critical failure pressure far exceeding 140MPa and excellent creep resistance at a high temperature of 175 ℃, ensuring the structural integrity and data stability of the instrument under extreme working conditions.

Born non-magnetic: The non-magnetic nature of titanium alloy perfectly eliminates interference with downhole electromagnetic wave signals, making logging data more accurate and reliable.

Stable corrosion resistance: In harsh environments rich in sulfides, the annual corrosion rate is less than 0.015mm, and the service life of the instrument is extended by more than three times, significantly reducing maintenance costs for customers.

In addition, its material processing performance is excellent, and our production efficiency has significantly improved. CNOOC has repeatedly praised the stability and data accuracy of our products. Dingding Titanium Industry is our trusted strategic partner!
