[China Instrument Network Instrument R&D] Recently, Wang Xinya, a member of the North East Oil Production Production Plant's Langdong operation area, successfully developed a new type of pressure gauge antifreeze device. When checking the use of self-developed wellhead pressure gauge anti-freeze device, it was found that the indicator data is accurate, the rotation is sensitive, and the use effect is good. It has solved the problem that the pressure gauges in the past were prone to freezing and improved the company’s effectiveness.


The North China Petroleum Administration has five drilling engineering companies, and there are 97 types of drilling rigs of various types. The downhole operation companies are equipped with advanced construction equipment such as world-class well logging equipment, and can complete all types of oil and gas wells in accordance with international standards. Perforation, oil testing, testing, acid fracturing, and workover, sidetracking and other construction tasks, is a company that integrates innovative large-scale equipment. The company also pays constant attention to innovation when it comes to cultivating talents, ensuring that everyone in the company dares to think and dare to do it. The research and development of the new pressure gauge anti-freeze device successfully validated the company's training philosophy.

In winter, the pressure gauges of the injection wells are often frozen. After the replacement of new pressure gauges, they are frozen and re-used, resulting in higher costs and affecting the correct admission of data. In response to this problem, Wang Xinya, Gao Jingtong and other technical innovation backbones used their brains to apply the antifreeze effect of the car, and developed a pressure gauge anti-freeze device, which solved the freezing problem of the water injection wellhead pressure gauge in winter and achieved safe production and cost reduction. Synergies serve two purposes.

Since the device was successfully applied, the wellhead pressure gauge anti-freezing device for water injection wells in Huabei Oilfield has been widely applied in 19 injection wells in the operation area, and there has been no case of frozen freezing of pressure gauges. A small device with a cost of less than 200 yuan, while ensuring safe production, reduced operating costs by nearly 100,000 yuan for the operation area in winter. While providing the company with high profits, it also demonstrates the importance of corporate innovation.
