Dongying Jiuli Petroleum Technology Co., Ltd. was established in 2014 and has passed the certifications of ISO9001, ISO14000, and ISO18000 management systems. The company is mainly engaged in the production and construction of coiled tubing equipment, the research and development of downhole tools, and technical services.

The company has established a high-quality scientific research and technical team, developed and produced a series of new products, which have been well applied on-site and received unanimous praise from users. All components of the coiled tubing equipment have been localized. In recent years, the coiled tubing equipment of our company has embarked on a difficult entrepreneurial path of transformation from "Made in China" to "Intelligently Made in China". Especially, the lightweight coiled tubing equipment has reached the domestic advanced level and has obtained a number of national patents. It has been widely applied and promoted in the Shengli Oilfield and has been affirmed by users.

The company has independently developed and produced new types of coiled tubing and supporting operation equipment, including 5 sets of coiled tubing workover trucks. The equipment integrates gas, liquid, and electrical technologies, with a high degree of automation and good reliability, and can complete a variety of oilfield operations. Its application scope covers various fields of oilfield operations such as oilfield drilling (slim hole wells, directional wells, sidetrack horizontal wells, underbalanced drilling, etc.), oil production, workover, and gathering and transportation, and has solved many problems that are difficult to solve by conventional operation technologies and methods. The operating depth of the coiled tubing unit can reach 6,000 meters, and the coiled tubing, injector head, drum, and other equipment have all been serialized.

Up to now, the coiled tubing operation equipment independently developed by our company has completed more than 600 well operations such as sand flushing and blockage removal, and tubing cutting in various oil production plants of the Shengli Oilfield, including Binnan, Gudong, and Gudao, and has successfully completed the construction tasks with high quality.

The company keeps pace with the times, seeks truth and innovation, and adheres to the development policy of "technology innovation driven, joint market development", insisting on promoting enterprise development through science and technology and constantly innovating. By leveraging our new technologies and products, we strive to collaborate with various sectors to expand and strengthen oilfield service equipment, and provide users with higher quality products and technical services.
