Artificial rock core for unconsolidated formation damage evaluation and manufacturing method of artificial rock core

The invention discloses an artificial rock core for unconsolidated formation damage evaluation and a manufacturing method of the artificial rock core. The artificial rock core comprises a steel cylinder, wherein rock core powder is filled and pressed into the steel cylinder; screens respectively cover two ends of the steel cylinder; ring sleeves which are fixedly connected with the ends of the steel cylinder are pressed outside the screens. The artificial rock core for the unconsolidated formation damage evaluation has the advantages that a natural rock core is crushed, ground and sieved, and is filled and pressed into the steel cylinder; the two ends of the steel cylinder are fixed by the screens and the ring sleeves; the artificial rock core is pressed at normal temperature without an adhesive, the original components of the natural rock core can be stored and keep active, a natural reservoir can be actually simulated, and the damage situation of the reservoir is truly reflected; the accuracy of an unconsolidated formation damage evaluation experiment and the accuracy of an evaluation result can be ensured.
