Chunhua oil field is characterized by the features of complicated fracture, low permeability and interbed thin layers. The complexity of fracture is typical i n Jiyan g depression. On the basis of early structural style and delicate structural sty le and for the purpose of reducing interlayer and lateral conflicts and increasi ng the reserves and oil production, a system engineering was used successively i n Chunhua oil field through more than 30 years of development, which includes pr oducing oil by elastic drive, waterflooding development, infill drilling, zonal production, progressive delineation, sporadic development, improvement, modifica tion of injectionproduction pattern and so on. And has got a good result in th e development of reservoirs with complicated fractures, low permeability and int erbed thin layers. The oil produc tion was more than 4×10~6t in 1980, and then from 1981 to 2000 this production was stably increased. Studies on the distribution rule of remaining oil in Chun hua oil field indicate that remaining oil enrichment region is virtually a lower potential close region formed by static shelter and dynamic potential of water. In practice, wells newly drilled in the lower structural region with high water cut did not produce water in early days. This maybe provides a new type and reg ion of potential tapping that is different from the socalled "potential regio n", which is the positive microstructures, and also have theoretic and practica l significance in guiding the direction of tapping potenti al old fields like Chunhua from 2001 to 2005.  纯化油田断裂的复杂性在济阳坳陷具有典型性 ,油藏储集层为低渗透、薄互层 ,因此油田开发 3 0年中的主要矛盾是平面与层间矛盾。以早期构造模型和精细构造模型为基础 ,以增储上产为核心 ,先后进行了弹性开发、注水开发、加密完善、分层开采、滚动探边、零星完善及注采结构调整等 ,很好地解决了油田平面矛盾并缓解了层间矛盾。近年来油田剩余油分布规律研究表明 :剩余油富集区实质上位于静态遮挡与动态水势控制而形成的低势闭合区 ,在构造低部位特高含水区的更低部位钻井 ,仍可获得不含水井的显著效果 ,这是与正向型微构造区不同的新类型与新潜力领域 ,对注水老油田的进一步挖潜具有重要的理论与实际意义。  It is hard to describe the scale and geometry of fracture and heterogeneous reservoirs because of their complicated structures.A new approach is presented to model natural fracture networks of hydrocarbon reservoirs especially,emphasized to check reservoir behaviors,to generalize the geometry structure of natural fracture networks on scales.The main ideal are to generalize the ideal fracture models using the method of Iterated Function System,to set up the fluid flowing models based on the Finite Element Method,to...

It is an effective tool for initiation and development of fractal geometry to investigate the prosperity of Euclid system. We describe characteristic of oil and gas flow and welltest analysis by this tool. On the conditions which are the supposes and definitions in the classic seepage flow dynamics are suitable to fractal oil and gas reservoir, and the mechanic laws in the fractal oil and gas reservoir are same formally with those in the classic seepage flow dynamics, based on the resolution of fractal oil and gas reservoir for single media, infinite strata and unstable flow by Tong dengke, we take use of Laplace transformation and attain the resolution for Laplace space. Then according to Stephest's numerical inversion, we get the numerical resolution for time domain of fractal oil and gas reservoir for single media, infinite strata and unstable flow. Depending on the mapping principle of traditional model curves and thinking about combining parameters and transforming coordination of typical curves, we get fractal Mckinley curves, investigate the character of these fractal Mckinley curves and use the practical test data of well A, The parameters we get are more reasonable, which is instruction for oil and gas exploration. In accordance with the above results, we concluded that the reservoir connected to well A is a complicated fracture network and has poor connectivity. What's more, fluid flow into well A not only from horizontal plane but also from direction paralleled to wellbore. Therefore we can see the flow of well A is not so simple. In additional, the well A is highly polluted. All of these results are consistent with those from the analysis of core and explanation for welllog.  分形几何理论的产生和发展为刻画非欧几里得几何系统(即分维系统)的性质提供了有效手段,使用这一工具对油气渗流规律进行重新认识,对传统描述油气运动的数学模型加以改进,并应用于试井分析中.根据传统模型图版制作原理,作出分形麦金利图版,可以看出:与传统模型拟和很差的实际数据,与分形麦金利图版的匹配效果却很好.说明油气藏更接近分维系统,所求得的各种参数更接近地下真实复杂情况,这对于油气田开发工作有重要的指导意义.   << 更多相关文摘
