Rock Physical and Digital Simulation with Verification

In recent years, with the development of earth science, the position of rock physics is improving in oil and gas exploration and rock analysis, meanwhile rock assay is necessary means to know the oil and gas geological features. This paper designs nine rock physics models, these models are divided into three groups, and every three in cement chips were added to different contents. By testing rock samples, then analyze the results to obtain variation between them. Because the largest density is iron, graphite followed when adding density larger than its own material in artificial rock samples, after mixing with a density greater than the density itself, and with the increase in volume when the content of the material, the density gradually increased to approaching the density of the material, on the contrary, the addition is smaller than its own density, mixed density smaller; the volume resistivity of the conductive particles content increases with the resistivity decreases, when adding to a high-impedance particles, the overall resistivity will increase; in short, the media contents on the particle composition and petrophysical properties of the rock sample in a great extent.
