| 摘 要： | 作者用自行研制的铸入剂和灌注设备,制作了四川地区多个层位具有代表性的好、中、差、极差四类碳酸盐岩储集岩的孔隙铸体。对其特征按分类进行观察研究,综合了储集性能优劣的标志。孔隙铸体直观地展示了不同类型孔(裂)隙之间的组合关系,它与孔隙结构参数相配合,可为评价储层以及分析储集性优劣的原因提供有力的依据。

| Abstract: | The authors of this paper use their own made porosity casting filler and filling equipment and prepare four types of porosity casts represent-ing good, ordinary, poor and very poor carbonate rocks from some typical sequences in Sichuan Area. Subsequently, the observations and analysis are carried out on reservoir rocks and integrated studies are made on the quality markers of the reservoir rocks. The direct observations of the porosity castings can illustrate the assemblage between the different porosites. Combined with the data of porous texture, it can evaluate the quality of reservoir rocks and provide scientific basis for reservoir analysis. |
