In order to meet the urgent needs of the oil industry for top drive, the country has solved the dilemma of relying on imports from top drive. Since the 1990s, it has organized domestic research forces to carry out research and development work, and listed the project as the 863 Torch Plan, but more than ten The research of the year only completed some of the results and failed to achieve industrial production.
In 2003, Tianyi Company seized this opportunity, borrowed foreign wisdom, boldly introduced the top drive scientific research results, and began comprehensive independent research and development. The company has invested more than 10 million yuan to train and reorganize enterprises through the introduction of experts and technicians. Internal technical strength, stubborn tackling, quickly mastered the key technology of top drive, and relying on domestic advanced processing and manufacturing capabilities and oilfield advantages, manufacturing and testing, strict control of the quality of top drive products, after three years of hard work, finally developed China The first 225-ton top drive unit. The success of the device not only broke the monopoly of a few countries in this field, but also filled a gap in China's top drive manufacturing technology, and also met the urgent needs of the oil industry for domestic top drive. The advancement of technology in the petroleum industry is of great significance.
The top drive unit independently developed by Tianyi Company has made many breakthroughs in key technologies such as main motor, back clamp, reduction gearbox, single guide rail and rotary head, and won 5 national patents. At the same time, the company's "Top Drives (Enterprise) Standards" has completely independent intellectual property rights. In 2005, Tianyi Company produced and sold 5 top drives and achieved sales revenue of more than 37 million yuan. This year the company plans to produce 10 top drives. It is understood that the demand situation of the top drive market is very good. According to the company's “Eleventh Five-Year†development plan, at least 30 top drive units can be produced per year by 2010, and 100 units will be produced during the five-year period. The cumulative output value will be Reached 700 million yuan.
The DQ-40DB top drive unit independently developed by Liaoning Tianyi Industrial Co., Ltd. was successful. This device with independent intellectual property rights successfully filled a gap in China's top area and drive manufacturing technology, and won 5 national patents. It was awarded the “World Productivity (China) Scientific Achievement Award†by the World Productivity Association China Chapter. . At present, it has successfully passed the factory acceptance and expert appraisal of China National Petroleum Corporation and has been put into mass production and application.
