Optimization study of encrypted deployment for dense well network

Abstract

At present, there are some problems in a certain block, such as the high ratio of oil and water wells, the high ratio of unconnected and unidirectional connectivity, the prominent plane contradiction, the great difference in the development effect between wells, the rapid rise of water cut, the large decline rate, and the small measure area. Based on the analysis of reservoir production status and remaining oil, well pattern encryption adjustment is carried out for a certain block. The three proposed encryption adjustment schemes are analyzed by numerical simulation, and the optimal scheme is selected. After field implementation, the encrypted well pattern has achieved good production results.
