摘　　要：目前虽然有许多种方法可以进行构造裂缝预测,但由于碳酸盐岩发育区裂缝发育的复杂性,需要综合研究构造裂缝定量预测的新方法.本文以哈萨克斯坦扎纳若尔碳酸盐岩凝析油田为研究和应用对象,提出了基于GIS系统的构造裂缝综合分析技术,通过构造DEM滤波分析、综合曲率分析、裂缝地形因子分析以及DEM构造应力场分析,提取与裂缝有关的构造起伏变化和侵蚀程度指标,对于碳酸盐岩储层利用DEM进行古水文地质条件分析,研究古地貌侵蚀和沉积的空间分布情况.根据构造应力场信息,综合分析不同构造部位岩层发生破裂的可能性及破裂程度,预测区域裂缝和局部构造裂缝发育带、发育程度及发育方向,并取得了不错的预测效果.Although there are several approach to prediction of structure cracks, but complexity of the fracture zone of carbonate rocks, need to study and solve new method of quantitative prediction of structure fractures. In this paper Zhanazhol condensate oilfield at Kazakhstan for research and application object, proposed analytic technology of structure fracture, By means of filtering analysis, structural curvature method, terrain factor analysis based on DEM with fracture, analysis of tectonic stress field and information synthesis, can be extracted index of changes in structure and erosion with the fracture, especially for carbonate reservoir using DEM can be analyzed ancient hydrological and geological conditions, to study spatial distribution of erosion for ancient landscape and deposition. Comprehensive study of information of tectonic stress field, GIS as a software platform for analysis of the possibility and the of the degree rupture for different structural parts, forecast regional and local structural fracture zone, the degree of development and developmental orientation. Purchase right predetermination effect.
