THE PREPARATION OF THIN SECTION FOR OIL-SATURATED ROCK SAMPLES
-
摘要: 通过对储集砂岩、砾岩和生物碎屑灰岩等饱含油岩心样品薄片磨制表明,针对不同类型的饱含油岩心样品,在薄片磨制过程中为了保持岩样原始结构和原油原始分布,需要采取不同的磨制过程,其关键是岩样固结技术。制作饱含油岩石薄片可在真空常压下或常温常压下浸透环氧树脂进行固结;饱含油胶结程度低松散状砂岩样品,需先用502胶或环氧树脂胶在载物片上进行固定和固结,并制成平面,然后再进行制片。Abstract: Preparation of thin section of oil saturated rock sections of different reservoirs,such as sandstone,conglomerate and carbonate rock,must adopt different technologies to maintain original structure of rock samples and original distribution of oil.The key is how to make rock samples concrete.Usually samples may be soaked and concreted in epoxy resin under the conditions of normal pressure and vacuum or normal temperature and normal pressure.For the incompact and oil saturated rock samples,it is necessary to concrete and fix them on the slide glass by glue 502 or epoxy resin and grind them flat at first,then the thin sections can be made.
