Abstract

According to the detailed description of the carrier bed Daqing delta fluvioglacial deposits, channel the sand package of the oil field is intermittently developed and the forecasting function is not sufficient with the expansion of the oil field to find suitable blocks, the principle of high-resolution stratigraphic sequence and the re-examination of the sedimentary system and characteristics of the sediments of the oil field have been introduced. By accurately comparing the strata, a sequence structure of 12 sediment units of the P oil reservoir of a given oil field was established, and sediment microfacies were subdivided. Through a study of the sediment characteristics of the oil reservoir P of the oil field come to be more continuous and extended than previously thought. Moreover, it is essential for the gradual development capacity of irreducible oil.
