Technical Study On Cementing Quality Evaluation And Statistical Analysis Of Adjusting Well In Daqing

Cementing Quality Evaluation Model and Evaluation Method of Daqing Oil Field is the internal adjustment of the characteristics of well developed research trial. The main study is to establish the impact of the factors cementing operation acquisition system to collect large amounts of data, including drilling, geological drilling, cementing operation, as well as cementing quality parameters such as description; the use of fuzzy gray relational theory and cementing quality Multivariate statistical methods; the use of orthogonal wavelet neural network and multi-factor theory of differential equations cementing quality evaluation model, the impact of various factors in a comprehensive evaluation. Research on the impact of the relationship between factors and the impact of factors on the combined effect of cementing quality in order to improve the quality of cementing.Daqing Oilfield adjustment well drilling and completion technology has been more mature, with the mid-and late into the oil field development and production plant for further cementing quality requirements, it is necessary to affect the quality of the factors cementing more sophisticated, comprehensive, systems analysis, Acquisition parameters affect the quality of cementing, the classification of statistical parameters, optimization parameters, to improve the quality of cementing. Cementing the past to improve the quality of the study also is limited to scattered, localized, single-factor studies, failed to form a comprehensive and integrated system under the influence of multiple factors to improve the quality of cementing. With the cementing technology, the impact from various factors to achieve improve cementing quality, and ensure the success of cementing operations, the normal follow-up projects, and the formation of a set of intelligent software quality evaluation cementing particularly important. Are therefore required to study the impact of the relationship between factors and the impact of factors on the combined effect of cementing quality in order to improve the quality of cementing. Oil has accumulated a wealth of information about the design and construction cementing data, experience. Use of these existing data and experience to establish factors affected the quality of cementing the relationship between the model and evaluation model for the establishment of cementing quality, reduce labor intensity of the statistical analysis, statistical analysis to improve the efficiency and accuracy to improve the district Block cementing quality, statistical analysis, forecasting and control, can be designed in cementing the main factors for the problems caused by the corresponding solutions to improve the quality of cementing, cementing the prevention of accidents and the complexity of the project took place.
