特殊人造岩心的类型及应用

Type and Application of Special Artificial Cores

介绍了石英砂环氧树脂胶结人造岩心的技术及优点以及特殊人造岩心的类型和应用,包括含黏土或砾岩颗粒人造岩心、特低渗岩心和带裂缝岩心以及加长的方形岩心和平面岩心的不同井网部署,平面可视胶结和填砂模型。石英砂环氧树脂胶结制备的人造岩心可以模拟砂岩油藏,在非均质性、渗透率、孔隙度方面模拟度高。实验的可对比性好,外观形状具备任意性。

The technology of making artificial cores is introduced by the cementation of quartzite and colophony and the type and application of special artificial cores,including the following type：mixing clay soil or conglomerate granule,particular low permeable sublayer and extension quadratic cores,fractured cores,areal cores with different well network,visualization areal cemented model or sand filling model.The artificial cores of making artificial cores by the cementation of quartzite and colophony can well simulate the aeolotropism,permeability,porosity and aeolotropism.Good chronotaxis in experiments and arbitray character are advantages of it.
