摘要: It has been found that the existence of chlorite and illite will lead to the rock wettability of oil affinity. Chlorite and illite are developed in shaly sandstone of Yingcheng Formation in Longfengshan area, the saturation index n of 7 rock samples is very high, with the highest of 14.57, whereas the cementation index m is low. The X-ray diffraction of clay and whole rock analysis of 7 shaly sandstone samples are carried out, and the relationship between chlorite and illite content vs. m and n is established. It is concluded that the low m value and high n value are caused by the wettability of rock. In order to verify the influence of wettability on the parameters of rock electricity, this paper discusses the method of making artificial shaly sandstone and the control of wettability. This study provides certain reference for determining the saturation model of shaly sandstone and improving the logging interpretation accuracy of shaly sandstone reservoirs.
