Description

technical field [0001] The invention relates to a reservoir pore evolution simulation experiment device, and belongs to the technical field of reservoir pore evolution simulation experiment equipment. Background technique [0002] Studying the pore structure of reservoirs and revealing the internal structure of oil and gas reservoirs is of great significance to the exploration and development of oil and gas fields. The physical properties of reservoirs are the result of the joint control of structural pattern, depositional environment and diagenesis. Due to the joint action of sedimentation and diagenesis, the distribution of reservoirs results in various pore types, complex pore structures and strong heterogeneity. Sedimentation has obvious control effects on the mineral composition, structure, sorting, rounding and matrix content of clastic rocks, and these factors have varying degrees of influence on the physical properties of the reservoir. With the increase of burial de...

Problems solved by technology

[0003] The vivid and diverse analysis of the formation and evolution process of reservoir pores plays a vital role in the study of reservoir pores. However, the current simulation of reservoir pore evolution is generally only realized by simple compaction. However, due to the During compaction, its edge cannot slip or move, and in the actual formation process, the rock samples of the reservoir will slide around after being stressed, and the size of the sample box cannot be regarded as infinite, which means This leads to inaccurate simulations, large deviations from reality, and the inability to simulate the effects of water pressure, dissolution, and cementation at water depths
