慕迪礁灰岩油田储层特征研究

Reservoir characteristics of Mudi reef limestone oilfield

构造内幕复杂的礁灰岩块状底水油田的研究目前是世界范围内的一个难题,根据测井、三维地震资料提出按储层类型进行井间对比的方法,得出了慕迪油田的地质格架。针对地质上的不确定问题,应用CMG数值模拟软件,利用双孔、双渗模型拟合了慕迪礁灰岩油田的生产动态历史,得出了比较确定的结论,进一步深化了对该礁灰岩储层的认识。

Study on block bottom water oilfield of reef limestone with complex structural inside story is a global challenge at present.Based on logging and 3D seismic data,this paper proposes interwell correlation method according to reservoir types,and obtains geologic framework of Mudi Oilfield.Facing the problem of uncertainty,it uses CMG numerical simulation software and dual-porosity and dual-permeability model to match production dynamic history of Mudi reef limestone oilfield,and draws a qualitative conclusion.
