Influence of Microscopic Pore Structure on Reservoir Producing Status Analysis by Mercury Injection

Abstract:

To guide the potential tapping and carry out adjustment plan, the conventional mercury injection experimental data in coring well X is analyzed by Logistic Regression analysis in SPSS 18 software. The main influence factors on reservoir producing status in the data are screened, which are the main factors from the data on microscopic pore structure; the relationship between microscopic pore structure and producing status is analyzed by capillary pressure curve and water-washing data. The result shows that, the influence of microscopic pore structure on producing status of un-tabulated reservoir is more powerful than its influence on that of tabulated reservoir; the main factor on producing status in mercury injection data of tabulated reservoir is average pore radius, the main factors on producing status in mercury injection data of un-tabulated reservoir is pore distribution peak position, permeability distribution peak value and maximum withdrawal efficiency.
