Abstract:

Reservoir microscopic pore structure directly affects the reservoir storage and permeability, so the research on reservoir microscopic pore structure characteristics can help to carry out reasonable classification evaluation of reservoir, and find out reservoir distribution law, improve the productivity and recovery ratio of oil and gas. Based on a large number of relevant literatures, this paper summarized and expounded the origin, test methods, theory research progress and comprehensive evaluation of reservoir microscopic pore structure, analyzed the main existing problems in the research of domestic reservoir microscopic pore structure, and pointed out that the research of the domestic micro structure is mainly based on traditional methods, having the problem of insufficient combination with domestic actual geological condition and lack of quantitative research.
