对裂缝型油藏来说,裂缝既是有效的储集空间又是重要的渗流通道,但裂缝发育情况复杂,具有很强的非均质性,常规的地质建模方法并不适用于裂缝建模。以中东地区某裂缝型碳酸盐岩稠油油藏为例,融合地质、测井、地震、动态等多种信息,将裂缝分为断裂破碎带、中等级别裂缝和小级别裂缝3个级别,首次提出确定性建模和随机建模相结合的方法建立裂缝储集相模型,在其约束下建立各级别缝的发育强度体,最后通过离散裂缝网络(DFN)模拟和参数场等效,得到各个级别缝的离散裂缝网络模型和裂缝属性模型,探索了一套针对复杂裂缝型储层的多信息融合的分级裂缝建模方法。
對裂縫型油藏來說,裂縫既是有效的儲集空間又是重要的滲流通道,但裂縫髮育情況複雜,具有很彊的非均質性,常規的地質建模方法併不適用于裂縫建模。以中東地區某裂縫型碳痠鹽巖稠油油藏為例,融閤地質、測井、地震、動態等多種信息,將裂縫分為斷裂破碎帶、中等級彆裂縫和小級彆裂縫3箇級彆,首次提齣確定性建模和隨機建模相結閤的方法建立裂縫儲集相模型,在其約束下建立各級彆縫的髮育彊度體,最後通過離散裂縫網絡(DFN)模擬和參數場等效,得到各箇級彆縫的離散裂縫網絡模型和裂縫屬性模型,探索瞭一套針對複雜裂縫型儲層的多信息融閤的分級裂縫建模方法。

For the fractured carbonate reservoir,fractures are effective reservoir space and primary channels. But the de-velopment of fractures is complex and the reservoir has strong heterogeneity. The normal geological modeling methods are not applicable to the fracture modeling. This paper takes X Oilfield in the Middle East Region as an example and establishes the technology of fracture modeling on a scale of fracture zones,medium-size fractures,and small-size fractures based on convergent multi-source information including geology,well-logging,seismic,and dynamic data. It is first proposed by the authors that the fracture reservoir facies model is established on the combination of the deterministic model and stochastic model method. Under the constraints of facies model,the development intensity bodies at different scale of fractures are established. Finally,a discrete fracture network(DFN)model and fracture property model are generated by means of DFN modeling and parameter field equivalence. In general,this paper discusses and studies a set of fracture modeling method converging with multi-source information on the basis of different scale of fractures for the complex carbonate reservoir.
