On September 25, 2015, China's internal combustion engine industry development summit forum was held at the Nanling Campus of Jilin University. Xing Min, executive vice president and secretary-general of China Internal Combustion Engine Industry Association, elaborated on the development status, existing problems and solutions of the internal combustion engine industry. He specifically mentioned that “internal combustion engines are the most potential and most intuitively effective Products, as a mainstream power machinery for a long period of time, cannot be shaken."
China Internal Combustion Engine Industry Development Summit Forum
As the host of the summit, Li Yuanyuan, academician of the Chinese Academy of Engineering and president of Jilin University, stated that as a large exporter of internal combustion engines, the transformation of China into a manufacturing powerhouse for internal combustion engines still needs a process, and industry associations, universities, research institutes, and manufacturing companies must work together. This summit forum is a good platform for full communication and exchange in all aspects of the industrial chain.
He Guangyuan, the former Minister of China's Ministry of Machinery Industry, who has been concerned about the development of the internal combustion engine industry, has been at the summit forum despite his high age. As a witness to the development of China's machinery industry, He Guangyuan recalled the years of first-line work such as foundry and forging at the factory. Memories of the past are even more important for development. "The internal combustion engine industry has the potential to be tapped, especially in respect of energy saving and emission reduction." He Guangyuan pointed out that it was summed up in three sentences: First, the internal combustion engine is not a substitute in a short time, and it is still the dominant driving force in decades; Second, the internal combustion engine industry, energy-saving emission reduction, alternative fuels is the direction of efforts; Third, from the manufacturing of large-scale internal combustion engine to a manufacturing powerhouse, internal combustion engine technology advancement, we must start from the key components.
At the same time, around the sustainable development of the internal combustion engine industry in China, Jiang Deming, former president of Xi’an Jiaotong University, put forward three requirements: Continuous improvement of product quality is the core of sustainable development. The China-Internet Association strongly supports conditional parts manufacturers to set up laboratories. Conditional factories should strive to open up foreign markets and occupy overseas markets of their products as soon as possible. The China Association for Internal Cooperation must assist relevant departments in the strict enforcement of laws and impose heavy penalties on fraud.
According to the current status of automobile development, it is expected that the auto sector will dominate the domestic market by 2025, with a global market share of 15%. At the same time, the overall competitiveness of vehicle companies will increase significantly, forming 2-3 global competitiveness. The world famous brand.
Drilling tool assembly (P, H, N and B)
Relevant description of products:
Retrieve the inner tube with an overshot without lifting out the whole rods string to obtain the core, the wireline coring system lifts the underground core sample out of the borehole through the overshot to take back the entire inner tube and conduct sampling analysis. This improves productivity of the work site and guarantees safety of core sample during drilling down.
The system is realized through a fully independent inner tube. During its working, the inner tube does not connect with the overshot but locates at the bottom of the coring Drilling Rod directly (behind the coring drilling bit). An assembly device is installed on top of the inner tube, which includes coring and recycling functions. When the inner tube is full of core sample, the overshot is placed to the bottom from the borehole through a steel wire rope and lifted out by a winch. After the inner tube assembly is lifted to the surface, an empty inner tube is placed to the bottom of the hole to recover the drilling. This improves well drilling efficiency.
Our company provides core barrel assmeblies of different diameters to meet customers' demands. The wireline coring system is applicable for most drilling conditions and standard DCDMA hole sizes (B, N, H and P).
Currently, the company provides two models of wireline coring systems: double-tube and triple-tube
Core barrel assembly: It consists of inner tube and outer tube groups.
The inner part consists of the following parts: spearhead assemly, retrival components, core sample collection component, landing shoulder, stop ring and other parts.inner tube group, independent from outer tube group, collects core sample sample during well drilling.
The outer tube part consists of parts , which includes locking coupling, adapter coupling, outer tube, etc. The outer tube group that is kept at the bottom of the hole all the time holds the inner tube assembly during drilling.
The triple tube coring system AU3 has the same components as the dual-tube. And its interior has a third tube that is known as liner tube of the inner tube.
Liner tube of the inner tube is placed in the inner tube. The triple tube system can realize overall recovery ratio of core sample when drilling stratum with coal, clay or bigger crack. The liner tube or split tube keeps the core sample at its receiving status to collect or load and store easily.
Only N, H and P sizes are available for the triple tube coring system.
