Aluminum Polishing Sheet is a special Aluminum Sheet.Its surface has been polished hence gives good performance in surface condition.The advantage of aluminum sheet is as follows:
1. Easy to process.

Zhanghai 502KH well is located in Zhangjuhe Village, Huangpi City, Hebei Province. The designed well depth is 5246 meters. The drilling depth is 5387 meters, the horizontal displacement is 4218.56 meters, and the horizontal well section is 602 meters long. The well began to drill sideways from 3454 meters in Zhanghai 502 well on December 26, 2005. The well was successfully delivered on February 5, with an average monthly drilling speed of 942.68 meters per month and a mechanical drilling rate of 7.03 meters per hour. .
It is reported that due to the deep side drilling depth, large displacement, large casing level and small borehole of Zhanghai 502KH well, the construction is very difficult. Dagang Drilling Company has developed scientific and rigorous technical measures such as anti-collision, anti-jamming and anti-spraying. The construction uses the MATRABAIL water-based drilling fluid to strengthen the management and use of solid control equipment and maintain the low solid phase low sand drill. Advance, adjust the mud performance before entering the oil layer, reduce the pollution of the oil layer by the filtrate, and effectively protect the oil and gas reservoir.
The team also boldly adopts new drilling technology and new technologies such as measurement while drilling + guiding motor + high-efficiency drill bit, which greatly improves the drilling speed. The well has adopted advanced screen completion technology and achieved good results.
The results show that the casting aluminum alloy with good casting property or deformation aluminum alloy with good processing plasticity can be obtained by adding certain Ba Au Du element.
2. Good conductivity and thermal conductivity.
The electrical and thermal conductivity of aluminum is second only to silver, copper and gold.
3. The density is small.
The density of aluminum and aluminum alloy is close to 2.7 g / about 1 / 3 of that of iron or copper.
4. High strength.
The strength of aluminum and aluminum alloy is high. The matrix strength can be strengthened by cold working to a certain extent, and some brands of aluminum alloy can also be strengthened by heat treatment.
5. Good corrosion resistance.
The surface of aluminum is easy to produce a dense and firm protective film of Al2O3, which can protect the substrate from corrosion.
Domestic onshore horizontal displacement maximum side drilling
On February 5th, the Zhanghai 502KH well constructed by the Dagang Oilfield Drilling Company 70152 team was successfully drilled. This well is the largest side-level drilling in the country with the highest level of land displacement, and it is also a high-difficult and ultra-deep horizontal well.
