Abstract

The invention relates to a rock wettability evaluating method used for petroleum drilling and exploration, which utilizes the frequency dispersion character of rock electrical parameter to conduct reservoir rock wettability evaluating. The dispersion information of phase has closer relationship with the wettability comparing with the resistivity; therefore the evaluating result is more accurate and reliable. The method has the characters of being simple, visual and convenient, which doesn't need special experiment device and the experiment period is short, the maneuverability is strong, the experiment process is simple, and can be conducted under normal temperature and pressure, and which also can be conducted under stimulating the high temperature and pressure of reservoir condition.

Description

Technical field: [0001] The invention relates to a process method for measuring and evaluating the wettability of reservoir rocks during oil drilling and exploration. Background technique: [0002] In the process of oil drilling and exploration, it is necessary to evaluate and measure parameters such as reservoir rock wettability through coring. These tasks are of great significance to oil reservoir exploration and even future development. At present, among the methods for determining rock wettability in the laboratory, quantitative measurement methods include contact angle measurement, Amott method, USBM method, automatic imbibition method, NMR relaxation method, etc., and qualitative measurement methods include Cryo-SEM method , Wilhelmy dynamic plate method, microporous membrane determination method, relative permeability curve method, etc. The measurement methods of these methods are complicated, and require the experimenters to have high experimental skills and strong ...
