孔隙铸体能够提供贮集岩的有关孔隙和渗滤方面的特征,是研究岩石孔隙结构的一种直观方法。通过对岩石孔隙铸体的观察,可研究致密砂岩和碳酸盐岩中的孔隙形状和它们的分布连通状况,为研究油(气)层的物理模型和数学模型提供直接依据。 孔隙空间复制技术,国外在50年代以前早有研究。随着科学的发展,各种浸染剂的问世,复制技术不断改进。目前岩石孔隙结构的复制技术有了飞速的发展。 我国这方面的研究开展得较晚。50—60
Porosity castings provide the relevant pore and diafiltration characteristics of reservoir rocks and are an intuitive way to study the pore structure of rocks. Through the observation of rock pore castings, the pore shapes and their connectivity in tight sandstone and carbonate rock can be studied, providing a direct basis for studying the physical model and mathematical model of oil and gas layers. Pore space replication technology abroad in the early 50 years before long. With the development of science, the advent of various kinds of immersion agents, replication technology continues to improve. At present the rock pore structure replication technology has been rapid development. Research in this area in our country was carried out later. 50-60
