Analysis of production capacity and technical level of high

(1) Production capacity

The production of petroleum machinery in China began in the 1950s and in the early 1980s.

The development of China's petroleum machinery industry has entered a climax.

At present, China has 416 enterprises engaged in the production of heavy oil pumps, including state-owned enterprises, township enterprises and professional research institutes, about 120,000 employees, the annual industrial output value of 15 billion yuan.

It has formed a development system composed of production enterprises, scientific research institutes, colleges and universities and user units.

From the situation of heavy oil pump, China's earliest production and maintenance of heavy oil pump manufacturers is built in 1939 Longmen Oil Pump Factory.

With the continuous discovery and development of oil fields, the consumption of heavy oil pumps is growing rapidly. In order to meet the needs, the repair factories of each oil field have entered the production field of heavy oil pumps.

Because the production and processing of the oil pump is very high and the process is complex, the earliest manufacturers to enter the heavy oil pump industry are mainly some state-owned large and medium-sized enterprises and some military enterprises.

Since the reform and opening up, the rapid development of township enterprises, strength gradually enhanced, a number of powerful township enterprises optimistic about the heavy oil pump industry of high profits have also joined, and with its flexible marketing model has been rapid development.

In recent years, with the continuous improvement of China's machinery manufacturing level, oil fittings are produced, many small businesses cannot produce the original parts can be purchased in a through professional manufacturers, the individual private enterprises to seize the favorable opportunity, increasing investment, into the industry, and gain a foothold on the part of the market.

Now formed in dagang, shengli oilfield company factory in the new century, the 388 factory and so on more than a dozen large state-owned enterprises as a representative of heavy oil pump factory is the leading domestic production, research and development, leading the development direction of heavy oil pump, dozens of smaller companies imitate the production, the assembly and develop some special products for heavy oil pump production pattern.

From the production capacity and varieties, China is specialized in heavy oil pump production manufacturers have reached dozens of, only the annual output of more than 3000 manufacturers have nearly 20, can produce more than 20 varieties of more than 100 specifications of domestic products, the total output in more than 100,000 sets.

And China's current domestic pump capacity will not exceed 76000, living capacity is far more than needed, many manufacturers have been in a state of starvation.

However, the huge attraction brought by the profits of heavy oil pumps makes the manufacturers before A not easily withdraw from the market. It can be predicted that in the future, the situation of heavy oil pump market supply exceeds demand will continue for a longer period of time.

(2) Technical level

China's heavy oil pump production technology after decades of development, technology has been greatly improved.

The first generation of heavy oil pump produced in China is a combination pump with multiple sections and short bushings, which is characterized by single function, poor reliability, limited processing capacity and technology.

This kind of pump processing technology is simple, can only meet the well condition is not complex shallow well needs, but its short life, large loss, can not be suitable for deep well production shortcomings affect the development of China's petroleum exploitation industry.

In the 1970s, simplified heavy oil pump was developed abroad. The emergence of simplified heavy oil pump overcame the performance defects of the first generation of NYP high viscosity pump, and the well was well applied in production and quickly promoted in the world.

In the 1980s, China began to produce heavy oil pump with cylinder type, and in 1984, the first production line of simple pump was introduced from abroad, which started the research and development of heavy oil pump and the localization of production line.

In 1994, the first domestic simplified pump production line was born in Dagang Oil.

This marks the high precision processing capacity of our country has been greatly promoted.

With the continuous improvement of processing technology and material, the wear-resisting and anti-corrosion performance of the home-made simplifying pump has been greatly improved, and the market share has gradually increased.

At present, more than 95% of heavy oil pumps used in our country are whole cylinder pumps, and domestic brands account for almost 10%.

With the continuous progress of technology, the whole cylinder pump is also in continuous improvement and evolution, more and more functions, there are sand control, wax prevention, gas prevention, pumping thick, pumping, mining, double action and other heavy oil pump.

China's heavy oil pump production enterprises through efforts, not only can produce a variety of heavy oil pumps in the world at present, and can develop new special pumps according to the needs of users, and in accordance with API standards or other special standards production.

China's heavy oil pump industry has formed a complete set of production process system including design and development, raw material production, spare parts processing and finished product processing, and the overall technical level has reached the international level in the mid-late 1990s.
