This paper introduces the basic principles of the gray system theory and the GM(1, N) model, and analyzes the factors affecting of the cementing quality. This paper selects nine major factors and dimension reduction by principal component analysis. Using the data after dimension reduction to establishment of gray system model to predict the quality of cementing, the simulation and prediction of the oil cementing the actual data is carried out by this method. The results show that the algorithm is stable, fast, and accurate forecasting, suitable for real-time requirements are relatively high occasions
