| 摘 要： | 四川的地震勘探以山地地震勘探为其主要特点。四十年来，基本基本形成了四大技术系列，即：山地地震采集技术系列；高陆复杂构造资料处理技术系列；碳酸夺储层横向预测技术系列；人机联作综合解释技术系列。针对山区资料特点，采用叠后深度偏移技术、山区静校正技术、去炕席干扰技术、高分辨率处理技术等，使构造成果精度大幅度提高。在新的处理解释技术推广区，地震解释的构造目的层深度与实钻结果的相对误差小于３％，其中７６％左

| Abstract: | Seismic exploration in Sichuan features seismic exploration in hilly area. Four major technical series have been developed and formed in the past 40 years. They are seismic data acquisition, data pro- cessing in high-steep complicated structures, lateral prediction in carbonate rock reservoirs and interactive interpretation. Based on hilly seismic data characteristics, a series techniques of depth-mi- gration after stack, static correction in hilly area, desheet interfer- ence, high resolutioin processing have been taken to improve the precision of the structural interpretation. In the areas where the new techniques have been popularly used, the relative errors of the tar- get layer depth got by the seismic interpretation compared with that made by drilling are less than 3%, and? 6% of them are less than 1.5%. Besides that, the Carboniferous reservoir prediction in the East Sichuan, such as prediction of thickness, Zones developed withporosity and permeability, well fractured zones in carbonate rock reservoirs, reef, etc., also has made obvious achievement. |
