Since the production test of Beizhong Block began in 1965, due to the need of development and adjustment, multiple sets of well patterns have been encrypted, such as primary encryption, secondary encryption, and triple encryption well patterns. Some new knowledge can be obtained on the distribution of the body. In order to improve the development effect of the oil field and further increase the recoverable reserves, in 2015, the reservoir was encrypted in the Beizhong block, and 163 wells were supplemented. The prediction accuracy and the analysis of the changes have made clear the changing laws of different types of sand bodies, and improved the understanding of the sand bodies.
