1KaV6Y5r7i$g0【中文摘要】 碳酸盐岩油藏的裂缝描述和油藏数值模拟技术研究一直是国内外碳酸盐岩油藏研究的热点和前缘,也是制约碳酸盐岩油藏开发的关键问题之一。本文针对Oseil油田碳酸盐岩油藏特性,利用地质建模和裂缝建模软件、物理模拟实验、油藏工程方法和数值模拟方法对Oseil油田碳酸盐岩油藏裂缝分布特征和开发问题进行系统研究,取得了以下一些新认识:1、利用Petrel和FracMan软件来建立Oseil油田碳酸盐岩油藏地质模型和裂缝模型,并应用蚂蚁追踪技术,给出裂缝密度的空间分布,为新井部署井位提供地质基础。2、利用物理模拟实验,设计了符合碳酸盐岩储层特征的平面物理实验模型、剖面二维可视化模型和类三维模型。在此基础上进行了裂缝和水平井不同配置和不同水平段长度对开发效果影响的研究。3、利用油藏工程方法,研究了Oseil油田油藏驱动能量、产量递减规律和各井含水变化规律。利用Newman乘积法推导建立了底水油藏水平井势分布公式,并结合实际生产资料分析了Oseil油田水平井避水高度。4、利用Eclipse软件对Oseil油田进行了历史拟合和对水平井水平段与裂缝夹角进行了研究,并在考虑了地质构造、单井控制储量、井间干扰等因素...更多后,优选了最佳的新井井位。  还原

【英文摘要】 The describing the fracture of carbonate reservoirs and technical research of numerical reservoir simulation has been the focus studied in carbonate reservoirs and foreordained affinity both at home and abroad all the time, restricts one of the key problems of the development in carbonate reservoirs too. This text directs against the characteristic of carbonate reservoirs in Oseil field, goes on systematic research of the characteristic of fracture distribution and development of carbonate reservoirs in Oseil field by utilizing geologic modeling and fractured modeling software, experiment of physical analogy, methods of petroleum reservoirs engineering and numerical simulation. The new research results we get are as following:1. We used Petrel and FracMan build geological model and fracture model of carbonate reservoirs in Oseil field, and applyed ant-tracking thchnology to offerd geologic basement to disposition of new wells, with spatial distribution of fracture density.2. Utilizing ...更多experiment of physical analogy, we designed experimental model of level physics, 2D visual model of level and 3D model according with characteristic of carbonate reservoirs. On this basis, we studied on the influence of development affect by carrying on fracture and horizontal well with different allocation and different length of level sections.3. Developing petroleum reservoir method, we developed drive energy of reservoirs, law of decline of production and regular pattern of containing water of wells in Oseil field. Then using Newman arithmetic method establish the formula about potential distribution of horizontal well of bottom water reservoir, and analyse the avoiding water height by actual means of production in Oseil field.4. Using Eclipse proceed history matching to Oseil field and research on level section of horizontal drainhole and included angle of fracture. Optimizing optimal new well location throug consdering geological structure, single well controlled reserves, interference of wells.  还原水利论文KMc~+K|)cd
