Experimental method for simulating actual fracture-vuggy carbonate rock through preparation of water-soluble material
The invention discloses an experiment method for simulating actual fracture-vug type carbonate rocks by preparing a water-soluble material, which is applied to the technical field of preparation of carbonate rocks and aims to solve the problem that the actual condition of carbonate rocks prepared in the prior art is still different from that of carbonate rock fractures and vugles in an actual stratum. According to the method, water-soluble particles wrapping oil or fluid in carbonate rock fractures and cavities in other actual strata are adopted, the water-soluble particles are randomly placed in a cement sample in the cement sample preparation process, the water-soluble particles can occupy a certain volume in a cement cube, and in the cement cube drying and forming process, the water-soluble particles are separated from the water-soluble particles; a small amount of water can cause the water-soluble particles to be dissolved, one part of fluid in the particles slowly permeates into a surrounding cement sample, and the other part of the fluid in the particles is left in the fracture cavity, so that the irregular fracture cavity capable of simulating the actual condition of the carbonate rock fracture cavity in the actual stratum is formed.
本发明公开一种水溶材料制备模拟实际缝洞型碳酸盐岩实验方法，应用于碳酸盐岩的制备技术领域，针对现有技术中所制备的碳酸盐岩与实际地层中碳酸盐岩缝洞实际情况仍旧存在差距的问题，本发明采用包裹油或其他实际地层中碳酸盐岩缝洞内的流体的水溶性颗粒，水泥试样制备过程中随机置于水泥试样内部，水溶性颗粒会在水泥立方体内部占据一定的体积，在水泥立方体干燥成形的过程中，少量的水分会导致水溶性颗粒发生溶解，颗粒中的流体一部分慢慢渗入周围水泥试样中，一部分则会留在缝洞内，形成能够模拟实际地层中碳酸盐岩缝洞实际情况的不规则缝洞。
