tungsten weight bar/sinker bar

Due to its high density, high hardness and high strength characteristics, tungsten sinker bar significantly improve the stability of drilling equipment and drilling depth, reduce equipment vibration and wear, improve drilling efficiency and safety, and promote industry technology upgrading.

Oil extraction is a complex and challenging task. Oil drilling needs to probe deeper to obtain formation characteristics. In this process, the drilling equipment must be heavy enough and strong enough to smooth out the upward resistance and increase the downward momentum. Equipment stability and drilling depth are key factors. Traditional weights are often inadequate in the face of higher stability requirements and deeper drilling depths. The tungsten weight bar successfully solves these problems by virtue of its unique physical and chemical properties.

Due to its high density (about 18.85 g/cm), high hardness (HRC35) and high strength (tensile strength of 700-1000 mpa),tungsten alloy can significantly improve the stability of drilling equipment, but also to increase the depth of drilling. For example, tungsten sinker bar are used because the self-weight is large enough to better reduce the vibration of the drilling equipment, which significantly reduces the wear and tear of the equipment and improves the accuracy of the drilling. In deep drilling, traditional materials are often unable to withstand excessive pressure and lead to performance degradation. The strength and high temperature resistance of tungsten alloy enable it to maintain stable performance in high temperature and high pressure environments.
