The TL seismic attribution analysis technique is growing with TL Seismic monitoring technique development from the late '80s in 20th century. It is a key technique that exerts an important influence on the TL seismic monitoring techniques. In the past nearly 20 years, it is mainly used for acquiring dependable TL seismic difference to provide dependable basis for follow-up developing plan. But it exists many shortcomings, so continuely enriching and perfecting the technique will helpful for promoting the TL seismic monitoring technique development, and have an important meaning on enhancing oilfield recovery ratio.This paper discusses the TL seismic attribution analysis technique by the numbers, including two main contents; the first part is the reservoir prediction, including static reservoir prediction and the remaining oil saturation prediction. All of them, sensitive attribution optimizing selection, typical sample selection and reservoir prediction methods play an important role on predicting reservoir.This paper puts forward a sensitive attribute optimization method with three steps, a typical sample selection method that based on relevant method, a combining prediction method that combines linear prediction with RBF prediction method, and their combination can obtain good predict result. On condition of lack of secondary logging data, the paper brings forward a method that combines first logging data with dynamic data to simulate secondary logging data, and lay foundation for predicting remaining oil saturation successfully.The second part is TL seismic difference analysis technique. The paper sums up the TL seismic difference analysis technique, points out their applicability, at the same time points out the attribution minus can be suitable to explain the TL seismic difference, and researchs the TL seismic difference law on average enery difference from model.The paper applies all kinds of techniques of the time-lapse attributes analysis techniques on SuiZhong 36-1 oil field. The result shows the TL seismic attribution analysis techniques obtain successful application in SuiZhong 36-1 oil field.
