The invention relates to a method for predicting a low-porosity and low-permeability clasolite effective reservoir at a high-diagenesis stage and belongs to the technical field of oil and gas exploration and development. The method is characterized in that a geological process response relationship is established through carrying out analysis, simulation and quantitative evaluation on a geological process affecting porosity, the original pore preservation and induced pore increase / decrease conditions of a reservoir are determined, thus, the current porosity of a low-porosity and low-permeability reservoir at the high-diagenesis stage is quantitatively evaluated, the development of the effective reservoir is predicted, and a basis is provided for reservoir evaluation. The method for predicting the low-porosity and low-permeability clasolite effective reservoir at the high-diagenesis stage has the advantages that the predictability is strong, the distribution of various clasolite effective reservoirs at different stages of high-diagenesis can be accurately predicted, the fine prediction on the distribution of effective reservoirs of a research target section can be achieved, and the predicted unit plane can reach a hectometer level; the theoretical basis is solid, and the condition of over reliance on the data of sampled points in the traditional method is avoided; the quantitative performance is good, the applicability is wide, and the information requirements are relatively low; and the evaluation, with different information foundations, on different exploration and development stages is facilitated.

The invention relates to a seismic robustness method based on interstory displacement. The story is used as the link of the column relative to the importance coefficient of the overall frame, and the story importance coefficient of the column based on the interstory displacement is proposed; the coefficient combines the traditional column to The overall importance of the frame is changed to be quantified to a specific floor, and its value reflects the impact of the column on the floor, especially a negative value means that setting the column has a negative effect on the seismic performance of the storey; The damage coefficient is used to establish specific indicators and methods for evaluating the seismic robustness of frame structures. The conclusion obtained based on the method of the present invention can truly reflect the robustness of actual engineering under different intensity earthquakes, and can point out the layers and columns that control the overall seismic robustness of the frame, and guide the FRP reinforcement design of the frame's seismic robustness effect.
