How the tungsten heavy alloy application for oil logging?

Usually, when it comes to environmental or geotechnical studies about groundwater, mineral, oil and gas exploitation, it is necessary to well logging for analyzing stratum situation exactly when drilling boreholes. Well logging is performed at various intervals during the drilling of the well and when the total depth is drilled, which could range in depths from 300 m to 8000 m (1000 ft to 25,000 ft) or more.

Since well logging always needs entering the earth as deeper as possible to get the characterization of wells, high-performance logging facility is required, and it should be heavy and firmer enough, so as to balance out much more upward resistance and enhance the downward impulse force. In fact, it should just work as counterweight for the whole part.Tungsten Heavy Alloy Ballast

Tungsten heavy alloy (WHA) is an excellent casing material for down-hole logging of oil wells. Casings must be sufficiently heavy to readily sink through materials such as barite mud and strong enough to withstand the hydrostatic pressure of this harsh environment. Most designs are highly machined for sensor and window positioning. Mechanical properties are very significant to the survivability of these rather large components.

1. High hardness: Tungsten Alloys have extremely high hardness (36HRC Max), which is harder than most metals. This enables tungsten alloys to maintain their strength and cutting performance under extreme high temperature and high pressure conditions, making them suitable for complex geological environments in petroleum drilling.


2. Wear resistance: Tungsten Alloy has excellent wear resistance and can resist wear and erosion in oil drilling. This allows tungsten alloys to extend the service life of drill bits and other drilling tools, reduce the frequency of maintenance and replacement, and improve work efficiency.


3. High density: Tungsten alloy has a higher density (18.5g/cc), making the drill bit more penetrating and stable. During the drilling process, tungsten alloy drill bits can better control the drilling direction and depth, improving the accuracy and efficiency of drilling.Tungsten Alloy For Oil Logging


4. Corrosion resistance: Tungsten alloy has good corrosion resistance and can resist corrosive media in oil wells, such as acidic liquids and high-temperature and high-pressure environments. This enables tungsten alloys to maintain their performance and lifespan under harsh working conditions.

Owning to high density as 18.5g/cm3 max, hardness as 36 HRC max, high wear-resistance, high impact resistance and excellent durability, tungsten heavy alloy (WHA) is quite suitable material for down-hole logging of underground water, oil and gas, etc. Special mechanical property is overweight large component in this case.Tungsten Alloy Rods For Counterweight
