WHA appliance for oil well logging

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 (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.

 

What is well 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.

Weights and Counterbalances for Aircrafts

Tungsten Heavy Alloys (WHAs) are the best choice when Designers in aerospace and defense industries require a material which combines high density, good

mechanical strength and which is easily machined.

The high density of WHAs makes it possible to significantly reduce the physical size of

components. This in turn, gives the benefit of greater control of weight distribution and

increases the sensitivity of controlling mechanisms. Where a large mass must be housed

within a restricted area, WHAs are the ideal material.

Advantages of Tungsten Alloy Fishing Weights/Sinkers

1. Small volume

High density make tungsten alloy fishing sinkers/weights smaller than the conventional lead fishing weights. It will be hung up far less with a tungsten sinker than with a lead sinker because of its smaller size.

2. Hard

It's harder than lead fishing weight. It will not be stuck in the jowl of the fish. So the shape will be maintained longer.

3. Strong wind resistance

As the high density of tungsten, the tungsten alloy fishing sinker makes your fishing easier. It is extremely sensitive and can actually help you "feel" what the bottom is made of and what your bait is bumping into, such as brush, rocks, mud, etc.

Tungsten fishing weights/eyes are an ideal, environment-friendly alternative to lead weights, which are toxic and increasingly being labeled an environmental hazard.

The main specifications are: drop type, bullet type, Circular tube type, ball type.

Tungsten Alloy Fishing Sinkers

The Fishing Sinkers are large proportion (> 18g/cc), small size. They are against strong wind, light into the water, sinking fast, and are the best alternative to lead sinkers. The Fishing Sinkers are best-selling in Europe, the United States and other developed countries.
Tungsten heavy alloy fishing sinker or tungsten alloy fishing weight is a weight used to force a lure or bait to increase its sink rate , anchoring ability, and casting distance. Tungsten heavy alloy fishing sinkers may be as small as 1/32 of an ounce for applications, even smaller for fly-fishing applications. They can get as large as several pounds or considerably more for deep-sea fishing. They are formed into nearly innumerable shapes for diverse fishing applications.Unlike lead, environmental concerns do not surround the usage of tungsten alloy fishing weight materials.

Tungsten Counterweight Grams

Tungsten Counterweight 25 grams - These Compact High Quality Counterweights are much smaller than lead counterweights of the same weight. - The small size and shape reduces chance of hookups and improves the look of your boat.
This counterweight is generally used on IOM B & C Rigs and all rigs on Marblehead, 10 Rater, A Class, EC12 etc.

Tungsten Alloy Counterweight Facts

Tungsten alloy counterweight is used in applications such as yacht, sailboat, submarine and other vessels crank camshafts, holders for well logging, racing eights, vibration damping and dynamic balancing.
Counterweights made from tungsten alloy
Due to its special properties, tungsten heavy alloy is usually used in the counterweight of yacht, sailboats, submarines, etc.
Chinatungsten bears abundant experience in supply of tungsten alloy counterweights to different overseas yachts’ manufacturers, up to the most specific designs requirement.
Brick-shape counterweights are the typical one we have ever been supplying in bulk quantities. By their own, our client designs and machines the bricks into the integrated counterweight parts with tungsten alloy pins’ connecting function.
