Preparation method of natural gas hydrate artificial rock core
The invention relates to a preparation method of a natural gas hydrate artificial rock core, and belongs to the field of natural gas hydrate artificial rock cores. The preparation method comprises the following steps: mixing rock and soil minerals with cement and water to obtain a cement paste mixture, and carrying out pressing treatment, demolding and coring, water vapor curing and drying on the cement paste mixture to obtain the artificial rock core, the mass ratio of the rock and soil minerals to the cement is (98.5-99): (1-1.5); the rock and soil mineral is prepared from 35 to 40 percent of calcite, 30 to 35 percent of quartz and 28 to 33 percent of clay mineral; the clay mineral is prepared from 24 to 28 percent of illite, 14 to 18 percent of kaolinite, 10 to 14 percent of chlorite and 44 to 48 percent of illite smectite mixed layer. According to the preparation method, a natural gas hydrate reservoir can be well reduced, the characteristics of the natural gas hydrate reservoir can be simulated, and the performance of the obtained artificial rock core is very close to that of a natural rock core.
本发明涉及一种天然气水合物人造岩心的制备方法，属于天然气水合物人造岩心领域。该制备方法包括以下步骤：将岩土矿物与水泥、水混合后得到水泥浆混合物，将所述水泥浆混合物进行压制处理、脱模取芯、水蒸气固化、烘干，得到人造岩心；所述岩土矿物与水泥的质量比为(98.5～99):(1～1.5)；所述岩土矿物由35～40％方解石、30～35％石英和28～33％粘土矿物组成；所述粘土矿物由24～28％伊利石、14～18％高岭石、10～14％绿泥石和44～48％伊蒙混层组成。本发明的制备方法可以较好地还原天然气水合物的储层，模拟天然气水合物储层的特点，获得的人造岩心与天然岩心的性能非常接近。
