| 摘 要： | 裂缝是塔里木盆地奥陶系碳酸盐岩沉积的重要渗流通道和储集空间，因此裂缝研究对油气藏开发具有重要意义。利用岩心、测井等资料对裂缝识别，选择裂缝相关参数（如线密度及充填性等）予以统计，研究塔中地区裂缝发育垂向及平面分布规律。结合裂缝发育规律，研究裂缝发育受岩性、层厚、断层及岩溶的影响关系。主要基于地质统计方法，预测塔中地区奥陶系裂缝发育的有利区带集中在主要断裂带附近及断裂带交汇处。预测的有利区带与其他方法如三维有限元数值模拟方法预测的区带一致。

| Abstract: | Fracture is an important percolation flow passage and oil-gas reservoir space in Ordovician carbonate sedimentary in Tarim Basin.The research of structural fracture is significant to oil-gas reservoir development.Applying to the analysis of rock cores and well-logging data,this paper chooses some related parameters(such as orientation,attitude,linear density and different types of fillings) and aims to find vertical development and distribution regulation in Ordovician of Tazhong Area.Furthermore,this study... |
