The Chongqing Natural Gas Purification Plant of PetroChina Southwest Oil & Gasfield Company will build a natural gas purification base of China as its developing strategic goal. To clarify the basic framework and work approaches and promote the construction process, based upon all the related data and information in this plant since 2008, we made clear the intension of base construction, six structural elements including technologies, services, pilot tests & technology popularization, technical training, skill appraisal, and culture system, according to which the corresponding six sub-bases were thus classified. In light of the present status, we put forward the following implementation proposals. (1) To build a base is not only a self-positioning and strategic objective, but a challenge and an opportunity for the plant. (2) Relevant standards, regulations and norms should be continuously compiled and promulgated to accumulate experiences for the standardized management of the plant and the standardized construction of new plants. (3) Technical and skilled talents should be constantly trained to strive for frontier leads and technological innovation, and in the state advocates of the integration of information and industrialization and "Made in China 2025", an intelligent purification plant should be constructed. (4) The overall inspection and maintenance service level should be enhanced to strengthen both soft and hard power of the training base. (5) The goal of "Factory Standardization, Talents Elite and Business Specialization" should be a driven force to achieve the great-leap-forward development and construction of a real purification base in China.
