摘要：克拉苏构造带盐下超深层储层属于裂缝性低孔砂岩储层，构造裂缝普遵发育，分布复杂且对单井产量影响较大。目前针对该地区储层裂缝的研究已投人大量的工作，主要体现在裂缝的捕述、表征和预测等方面，但由于该地区地震资料分辨率低、岩心资料少、成像测并多解性强，裂缝的研究受到一定程度的限制，生产中仅应用了裂缝密度、开度等统计数据。笔者综合野外露头、岩心和测并等资料，从裂缝组合的角度出发，

Abstract: The ultra-deep reservoirs beneath salt in the Kelasu structural belt belong to low porosity and fractured sandstone reservoir. Tectonic fractures are common in this area and show a complex distribution pattem. These: widely distributed tectonie fractures have large influence on single-well production of Kelasu structural belt. At present, research on reservoir fracture in this area is mainly focused on description, characterization, and prediction of fractures. However, due to low resolution of seismic data, limited core data and uncertainties in interpretation of images of well logging, the study of is limited. Only some statistical data such as fracture density and fracture opening are applied in the proxcess of hydrocarbon exploration. Outerop, core, and well logging data were used. In this stuxdy. research on reservoir fracture and combinations of fractures is carried out in this area. It is found that there are primary and secondary cracks. The scale of main cracks is larger than that of the secondary crarks. The primary eracks are generally perpendieular to the strata, and are mostly tension cracks or tensionshear cracks. The secondary cracks are generally associated the main cracks, There are many different contacts between the eracks, mainly in "T", " > ", “v", “y", and “ " shapes. According to the distribution of contacts
