| 摘 要： | 在三维模型表达中,相对于PEBI、径向(Radial)网格而言,角点网格是目前油气田开发研究比较通用的一种三维模型。它在表达复杂断块、油藏非均质性上较为突出。在油气勘探研究中,一般使用常规的面模型来进行各种定量模拟评价,这对于精度要求越来越高的油气成藏过程定量模拟与分析而言,显得精度不够。因此,基于角点网格模型的油气成藏过程的算法研究和应用在勘探评价中显得尤为重要。探讨了角点网格模型的空间信息与属性信息的管理与表达优势,讨论了如何将传统的面模型模拟算法改进成新的角点模型,研究了相应的算法,分析了其中的主要难点及解决方案,其中包括多尺度空间加密、角点网格结构及表达模型的优势、各单元网格岩性属性提取与使用、烃源岩厚度分配、运移网格间的匹配关系等问题,从三维表达、五史(构造史、热史、生烃史、排烃史及运聚史)所遇到的主要问题及解决方案进行了剖析。 |

| Abstract: | In the expression of 3D model and in terms of several grids like PEBI、Radial, corner point grid was one of the popular 3D models used in present research of oil and gas exploitation for its outstanding behavior in the expression of complex fault block and reservoir heterogeneity. In the research of oil and gas exploitation, routine surface model was generally used to conduct all kinds of quantitative simulation evaluation; it was hard to meet the precision requirements of quantitative simulation and analysis for hydrocarbon accumulation process as they had more and more higher requirement on precision; so the algorithm research and application of hydrocarbon accumulation process based on corner point grid model played an important role. The authors discussed the management and expression advantages for the spatial information and attribute information of corner point grid model. Based on the corner point grid model, the authors discussed the related algorithm, the main difficulties and solution plans on how to transfer the conventional surface model simulation algorithm into corner point grid model. The authors studied the corner point grid structure and its advantages in expressing model, lithologic attribute extraction and application of each unit grid, hydrocarbon source rock thickness distribution, matching relationship of the transporting grid. The authors analyzed the problems of 3D expression and five histories （tectonic history, geothermal history, hydrocarbon generation history, expulsion history and accumulation history） and their solution plans. |
