Research on the evaluation method of customer satisfaction index and its improvement in drilling engineering technology

this paper focused on the petroleum engineering services and the data of path and regression analysis from users of each drilling engineering company were calculated by the partial least squares method. Based on the whole comparison, This paper has achieved the evaluation of the existing user satisfaction evaluation system of drilling engineering services, and mainly illustrates key factors and effects of user satisfaction and provides analysis on its observed variables and structural variables. Through the contrast, assessment and recommendations were made for the current level of each company in the industry by synchronic and diachronic comparisons. And from a micro perspective, improvements of structural variables within the companies were suggested by calculating the weight and scores of each observed variable. The results indicate: Although some structural variables are occupied in the advanced level companies in terms of the oil drilling engineering and technical services, these also have some disadvantages. This means that leading not only a leader in integrated comprehensive leading enterprises should be made based on the structure of the observed variables corresponding to the variable improvements. And company should achieve high customer satisfaction and customer loyalty for companies to bring more economic value and social value. And also they should achieve comprehensive evaluation of the oil industry drilling engineering and technical services companies, customer satisfaction and business practices satisfaction balanced development. A comprehensive evaluation of companies in the petroleum drilling engineering service industry was madden, promoting the balanced development of the mutual satisfaction of users and companies.
