Abstract: front page image
(EN) The present invention relates to a method for measuring porosity utilizing electron microscopic images of rock samples reacted with a gadolinium compound. The method for measuring porosity according to the present invention comprises the steps of: (a) capturing a first image by performing electron microscopic imaging on a rock sample to be measured for porosity; (b) determining, from the first image, a first area of a part to be understood as heavy minerals; (c) immersing the rock sample in an aqueous solution, in which a gadolinium compound is dissolved, so that the aqueous solution flows into pores inside the rock sample to precipitate in the pores; (d) capturing a second image by performing electron microscopic imaging on the rock sample after the precipitation of the gadolinium compound; and (e) determining, from the second image, a second area of a part to be understood as heavy materials and pores, and then subtracting the first area from the second area to determine a pore area of the rock sample.
(FR) La présente invention concerne un procédé de mesure de porosité utilisant des images d'étude microscopique d'échantillons de roche mis à réagir avec un composé de gadolinium. Le procédé de mesure de porosité selon la présente invention comprend les étapes consistant à : (a) capturer une première image par réalisation d'une imagerie d'étude microscopique sur un échantillon de roche dont la porosité doit être mesurée ; (b) déterminer, à partir de la première image, une première zone d'une partie devant être considérée comme étant des minéraux lourds ; (c) immerger l'échantillon de roche dans une solution aqueuse, dans laquelle est dissous un composé de gadolinium, de telle sorte que la solution aqueuse s'écoule dans des pores à l'intérieur de l'échantillon de roche pour se précipiter dans les pores ; (d) capturer une seconde image par réalisation d'une imagerie d'étude microscopique sur l'échantillon de roche après la précipitation du composé de gadolinium ; et (e) déterminer, à partir de la seconde image, une seconde zone d'une partie devant être considérée comme étant des matières lourdes et des pores, puis soustraire la première zone de la seconde zone pour déterminer une zone de pore de l'échantillon de roche.
(KO) 본 발명은 가도리니움 화합물을 반응시킨 암석 시료의 전자현미경 이미지를 활용한 공극률 측정방법에 관한 것이다. 본 발명에 따른 공극률 측정방법은, (a)공극률 측정의 대상이 되는 암석 시료에 대하여 전자 현미경 촬영을 수행하여 제1이미지를 촬영하는 단계; (b)제1이미지에서 중광물로 파악되는 부분의 제1면적을 파악하는 단계; (c)가도리니움 화합물이 용해되어 있는 수용액에 암석 시료를 침지시켜 암석 시료 내부의 공극에 수용액이 유입되어 침전되도록 하는 단계: (d)가도리니움 화합물이 침전된 후 암석 시료에 대하여 전자 현미경 촬영을 수행하여 제2이미지를 촬영하는 단계; 및 (e)제2이미지에서 중광물 및 공극으로 파악되는 부분의 제2면적을 파악한 후, 제2면적으로부터 제1면적을 제하여 암석 시료의 공극 면적을 파악하는 단계;를 포함하여 이루어진다.
