【Abstract】 Reservoir heteroneity of E 2S 6 1 oil bearing formation and the division standard of the uncontinuous intercalations in it were studied based on the geologic data and logging data from 40 wells in Duo Ⅰ member. Four stable shale intercalations were determined, thus the oil bearing formation is divided into five sandbody units by them. The distribution of the four intercalations was also studied. The space distribution of the impermeable intercalations in the five units were described by distribution frequency and distribution density. The great the distribution frequency and density, the worse the quality of a sandbody unit, and in a unit, there may be remaining oil distribution enrichment where the values of the distribution frequeucy and density are great.更多还原
